Accounting Policies [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION:
	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with instructions to Form 10-Q and Rule 10-01 of Regulation S-X. In accordance with Rule 10-01, the accompanying unaudited condensed consolidated financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete consolidated financial statements. The accompanying year-end condensed consolidated balance sheet was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. In management's opinion, all adjustments, including normal recurring accruals and adjustments, necessary for a fair statement of the Authority's operating results for the interim period, have been included. In addition, certain amounts in the accompanying 2014 supplemental condensed consolidating financial statements have been reclassified to conform to the 2015 presentation.
	The gaming market in the Northeastern United States is seasonal in nature, with peak gaming activities often occurring at Mohegan Sun and Mohegan Sun Pocono during the months of May through August. Accordingly, the Authority's operating results for the three months and six months ended March 31, 2015 are not necessarily indicative of operating results for other interim periods or an entire fiscal year.
	The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Authority's Annual Report on Form 10-K for the fiscal year ended September 30, 2014.
	Principles of Consolidation
	The accompanying condensed consolidated financial statements include the accounts of the Authority and its majority and wholly-owned subsidiaries and entities. In accordance with authoritative guidance issued by the Financial Accounting Standards Board (the “FASB”) pertaining to consolidation of variable interest entities, the accounts of Salishan-Mohegan are consolidated into the accounts of Mohegan Ventures-NW and the accounts of NEBW are consolidated into the accounts of Mohegan Lacrosse as Mohegan Ventures-NW and Mohegan Lacrosse are deemed to be the primary beneficiaries. In consolidation, all inter-company balances and transactions were eliminated.
	Long-Term Receivables
	Long-term receivables consist primarily of receivables from affiliates and others and were primarily included in other assets, net, in the accompanying condensed consolidated balance sheets. The following table presents a reconciliation of long-term receivables, including current portions, and the related reserves for doubtful collection of these long-term receivables (in thousands):

	Fair Value of Financial Instruments
	The fair value amounts presented below are reported to satisfy disclosure requirements pursuant to authoritative guidance issued by the FASB pertaining to disclosures about fair values of financial instruments and are not necessarily indicative of amounts that the Authority could realize in a current market transaction.
	The Authority applies the following fair value hierarchy, which prioritizes the inputs utilized to measure fair value into three levels:
	•	Level 1 - Quoted prices for identical assets or liabilities in active markets;
	•	Level 2 - Quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in inactive markets or valuations based on models where the significant inputs are observable or can be corroborated by observable market data; and
	•	Level 3 - Valuations based on models where the significant inputs are unobservable. The unobservable inputs reflect the Authority's estimates or assumptions that market participants would utilize in pricing such assets or liabilities.
	The Authority's assessment of the significance of a particular input requires judgment and may affect the valuation of financial assets and liabilities and their placement within the fair value hierarchy.
	The carrying amount of cash and cash equivalents, receivables, trade payables and promissory notes and certain credit facilities approximates fair value. The estimated fair value of the Authority's financing facilities and notes were as follows (in thousands):
		March 31, 2015
		Carrying Value		Fair Value
	Senior Secured Credit Facility - Revolving	$	50,000	$	48,813
	Senior Secured Credit Facility - Term Loan A	$	115,960	$	114,078
	Senior Secured Credit Facility - Term Loan B	$	713,569	$	714,567
	2013 9 3/4% Senior Unsecured Notes	$	500,000	$	532,500
	2012 11% Senior Subordinated Notes	$	272,044	$	274,502
	The estimated fair values of the Authority's financing facilities and notes were based on Level 2 inputs (quoted market prices or prices of similar instruments) on or about March 31, 2015.
	Impairment of Project Horizon
	In September 2008, the Authority suspended certain elements of its Project Horizon expansion due to a slowdown in business volumes and uncertainties in the financial markets. Costs incurred on the suspended elements related to excavation and foundation work for a planned podium and new hotel tower, as well as professional fees for design and architectural work. During its fourth quarter ended September 30, 2010, the Authority re-evaluated its plans with respect to the development of the new hotel element of the project, and based on a modified plan, which encompassed a smaller hotel to be located closer to the existing hotel, determined that certain assets related to the suspended elements did not have any future benefit to the Authority. Accordingly, in fiscal 2010, the Authority recorded a related $58.1 million impairment charge. During its fourth quarter ended September 30, 2014, the Authority further re-evaluated its modified plan, which included a hotel to be developed and owned by an instrumentality of the Tribe, as well as a third-party developed and owned retail center, and, based on new design plans, including the final location of the planned hotel, determined that certain design and earthwork related assets did not have any future benefit to the Authority. Accordingly, in fiscal 2014, the Authority recorded an additional $5.0 million impairment charge.
	In March 2015, the Mohegan Tribal Finance Authority (“MTFA”), a wholly-owned instrumentality of the Tribe, agreed to develop the planned hotel. The Authority received approximately $1.3 million as payment for the carrying value of the remaining hotel related assets which were transferred to MTFA. Concurrent with this transaction, the Authority re-evaluated the planned third-party developed and owned retail center, including master planning costs, and determined that these elements of the project were no longer feasible at this time. Accordingly, the Authority determined that the related assets did not have any future benefit, and, during its second quarter ended March 31, 2015, the Authority recognized a related $2.5 million impairment charge, which was recorded in the accompanying condensed consolidated statements of income for the three months and six months ended March 31, 2015. As of March 31, 2015, there were no assets remaining related to the suspended elements of Project Horizon.
	New Accounting Standards
	In May 2014, the FASB issued an accounting standard update on revenue recognition that will be applied to all contracts with customers. The update requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. It also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. This guidance will be required to be applied on a retrospective basis, using one of two methodologies, and will be effective for annual reporting periods beginning after December 15, 2016, with early application not being permitted. However, in April 2015, the FASB issued proposed guidance that would defer the effective date by one year. The Authority is currently evaluating the impact that this guidance will have on its financial position and results of operations.
	In August 2014, the FASB issued an accounting standard update which provides guidance on determining when and how to disclose going concern uncertainties in the financial statements. The update requires management to perform interim and annual assessments of an entity's ability to continue as a going concern within one year of the date the financial statements are issued. It also requires management to provide certain disclosures if conditions or events raise substantial doubt about the entity's ability to continue as a going concern. This guidance will be required for annual reporting periods ending after December 15, 2016, and interim reporting periods thereafter, with early application permitted. The Authority is currently evaluating the impact that this guidance will have on its financial position and results of operations.
	In February 2015, the FASB issued an accounting standards update which amends existing requirements applicable to reporting entities that are required to evaluate whether certain legal entities should be consolidated. This guidance will be required to be applied either on a retrospective or modified retrospective basis and will be effective for annual reporting periods beginning after December 15, 2015, and interim reporting periods thereafter, with early application permitted. The Authority is currently evaluating the impact that this guidance will have on its financial position and results of operations.
In April 2015, the FASB issued an accounting standard update to clarify the required presentation of debt issuance costs. The update requires that debt issuance costs be presented in the balance sheet as a direct reduction from the carrying amount of the related debt liability rather than as an asset. This guidance will be required to be applied on a retrospective basis and will be effective for annual reporting periods beginning after December 15, 2015, and interim reporting periods thereafter, with early application permitted. The Authority is currently evaluating the impact that this guidance will have on its financial position and results of operations.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION	ORGANIZATION:
	The Mohegan Tribe of Indians of Connecticut (the “Mohegan Tribe” or the “Tribe”) established the Mohegan Tribal Gaming Authority (the “Authority”) in July 1995 with the exclusive authority to conduct and regulate gaming activities for the Tribe on Tribal lands and the non-exclusive authority to conduct such activities elsewhere. The Tribe is a federally-recognized Indian tribe with an approximately 544-acre reservation situated in Southeastern Connecticut, adjacent to Uncasville, Connecticut. Under the Indian Gaming Regulatory Act of 1988, federally-recognized Indian tribes are permitted to conduct full-scale casino gaming operations on tribal lands, subject to, among other things, the negotiation of a compact with the affected state. The Tribe and the State of Connecticut entered into a compact (the “Mohegan Compact”), which was approved by the United States Secretary of the Interior. The Authority is primarily engaged in the ownership, operation and development of gaming facilities. In October 1996, the Authority opened Mohegan Sun, a gaming and entertainment complex situated on an approximately 185-acre site on the Tribe's reservation. The Authority is governed by a nine-member Management Board, whose members also comprise the Mohegan Tribal Council, the governing body of the Tribe. Any change in the composition of the Mohegan Tribal Council results in a corresponding change in the Authority's Management Board.
	As of March 31, 2015, the following subsidiaries were wholly-owned by the Authority: Mohegan Basketball Club, LLC (“MBC”), Mohegan Golf, LLC (“Mohegan Golf”), Mohegan Lacrosse, LLC (“Mohegan Lacrosse”), Mohegan Commercial Ventures-PA, LLC (“MCV-PA”), Mohegan Ventures-Northwest, LLC (“Mohegan Ventures-NW”), Mohegan Ventures Wisconsin, LLC (“MVW”), MTGA Gaming, LLC (“MTGA Gaming”), Downs Lodging, LLC ("Downs Lodging") and Mohegan Gaming Advisors, LLC ("Mohegan Gaming Advisors").
	MBC owns and operates the Connecticut Sun, a professional basketball team in the Women's National Basketball Association (the “WNBA”). MBC currently owns a 4.2% membership interest in WNBA, LLC.
	Mohegan Golf owns and operates the Mohegan Sun Golf Club in Southeastern Connecticut.
	In October 2014, the Authority formed Mohegan Lacrosse as a wholly-owned unrestricted subsidiary. Mohegan Lacrosse holds a 50% membership interest in New England Black Wolves, LLC (“NEBW”), which was formed with an unrelated third-party to own and operate the New England Black Wolves, a professional indoor lacrosse team in the National Lacrosse League.
	MCV-PA holds a 0.01% general partnership interest in each of Downs Racing, L.P., Backside, L.P., Mill Creek Land, L.P. and Northeast Concessions, L.P. (collectively, along with MCV-PA, the “Pocono Subsidiaries”), while the Authority holds the remaining 99.99% limited partnership interest in each entity. Downs Racing, L.P. (“Downs Racing”) owns and operates Mohegan Sun Pocono, a gaming and entertainment facility situated on an approximately 400-acre site in Plains Township, Pennsylvania, and several off-track wagering facilities located elsewhere in Pennsylvania (collectively, the “Pennsylvania Facilities”). The Authority views Mohegan Sun and the Pennsylvania Facilities as two separate operating segments.
	Mohegan Ventures-NW and a subsidiary of the Tribe hold 49.15% and 10.85% membership interests in Salishan-Mohegan, LLC (“Salishan-Mohegan”), respectively.

	Senior Secured Credit Facilities
	In November 2013, the Authority entered into a loan agreement among the Authority, the Tribe, the Guarantors as defined below, RBS Citizens, N.A. as Administrative and Collateral Agent and the other lenders and financial institutions party thereto, providing for $955.0 million in aggregate principal amount of senior secured credit facilities (the “Senior Secured Credit Facilities”), comprised of a $100.0 million senior secured revolving credit facility (the “Revolving Facility”), a $125.0 million senior secured term loan A facility (the “Term Loan A Facility”) and a $730.0 million senior secured term loan B facility (the “Term Loan B Facility"). The Senior Secured Credit Facilities mature on June 15, 2018, subject to extension based on the satisfaction of certain conditions to November 19, 2018 (in the case of the Revolving Facility and the Term Loan A Facility) and November 19, 2019 (in the case of the Term Loan B Facility).
	The Term Loan A Facility amortizes in equal quarterly installments in an aggregate annual amount equal to 5.0% of the original principal amount for the first year after the closing date, 7.5% of the original principal amount for the second year after the closing date and 10.0% of the original principal amount in each year thereafter, with the balance payable on the maturity date of the Term Loan A Facility. The Term Loan B Facility amortizes in equal quarterly installments in an aggregate annual amount equal to 1.0% of the original principal amount. Amortization of the Term Loan A Facility and Term Loan B Facility began with the first full fiscal quarter after the closing date.
	As of March 31, 2015, amounts outstanding under the Revolving Facility, Term Loan A Facility and Term Loan B Facility totaled $50.0 million, $116.4 million and $720.9 million, respectively. As of March 31, 2015, letters of credit issued under the Revolving Facility totaled $3.0 million, of which no amount was drawn. Inclusive of letters of credit, which reduce borrowing availability under the Revolving Facility, and after taking into account restrictive financial covenant requirements, the Authority had approximately $46.6 million of borrowing capacity under its Revolving Facility and Line of Credit as of March 31, 2015.
	Borrowings under the Senior Secured Credit Facilities incur interest as follows: (i) for base rate loans under the Revolving Facility and Term Loan A Facility, a base rate equal to the highest of (a) the prime rate, (b) the federal funds rate plus 50 basis points and (c) the one-month LIBOR rate plus 100 basis points (the highest of (a), (b) and (c), the “base rate”), plus a leverage-based margin of 250 to 350 basis points; (ii) for Eurodollar rate loans under the Revolving Facility and Term Loan A Facility, the applicable LIBOR rate plus a leverage-based margin of 350 to 450 basis points; (iii) for base rate loans under the Term Loan B Facility, the base rate (subject to a 2.0% floor) plus 350 basis points; and (iv) for Eurodollar rate loans under the Term Loan B Facility, the applicable LIBOR rate (subject to a 1.0% floor) plus 450 basis points. The Authority also is required to pay a leverage-based commitment fee of between 37.5 and 50 basis points for unused commitments under the Revolving Facility. Interest on base rate loans is payable quarterly in arrears. Interest on Eurodollar rate loans of three months or less is payable at the end of each applicable interest period and for Eurodollar rate loans of more than three months, interest is payable at intervals of three months duration after the beginning of such interest period.
	As of March 31, 2015, the $50.0 million outstanding under the Revolving Facility was comprised of a $9.0 million base rate loan based on a base rate of 3.25% plus 325 basis points and $41.0 million in Eurodollar rate loans based on a Eurodollar rate of 0.18% plus 425 basis points. The commitment fee was 0.50% as of March 31, 2015. As of March 31, 2015, the $116.4 million outstanding under the Term Loan A Facility was based on a Eurodollar rate of 0.28% plus 425 basis points. As of March 31, 2015, the $720.9 million outstanding under the Term Loan B Facility was based on the Eurodollar rate floor of 1.0% plus 450 basis points. As of March 31, 2015 and September 30, 2014, accrued interest, including commitment fees, on the Senior Secured Credit Facilities was $230,000 and $212,000, respectively.
	The Authority's obligations under the Senior Secured Credit Facilities are fully and unconditionally guaranteed, jointly and severally, by the Pocono Subsidiaries, MBC, Mohegan Golf, Mohegan Ventures-NW, MVW, WTG and MTGA Gaming (collectively, the “Guarantors”). The Senior Secured Credit Facilities are collateralized by a first priority lien on substantially all of the Authority's property and assets and those of the Guarantors (other than MBC), including the assets that comprise Mohegan Sun Pocono and a leasehold mortgage on the land and improvements that comprise Mohegan Sun (the Authority and the Guarantors, other than MBC, are collectively referred to herein as the “Grantors”). The Grantors also are required to pledge additional assets as collateral for the Senior Secured Credit Facilities as they and future guarantor subsidiaries acquire them.
	The Senior Secured Credit Facilities contain customary covenants applicable to the Authority and its restricted subsidiaries, including covenants governing: incurrence of indebtedness, incurrence of liens, payment of dividends and other distributions, investments, asset sales, affiliate transactions, mergers or consolidations and capital expenditures. Additionally, the Senior Secured Credit Facilities include financial maintenance covenants pertaining to total leverage, secured leverage and minimum fixed charge coverage.
	As of March 31, 2015, the Authority and the Tribe were in compliance with all respective covenant requirements under the Senior Secured Credit Facilities.
	The Authority continues to monitor revenues and manage expenses and enhance operating efficiencies to ensure continued compliance with its financial covenant requirements under the Senior Secured Credit Facilities. While the Authority anticipates that it will remain in compliance with all covenant requirements under its Senior Secured Credit Facilities for all periods prior to maturity, it may need to increase revenues or offset any future declines in revenues by implementing additional cost saving and other initiatives to ensure compliance with these financial covenant requirements. If the Authority is unable to satisfy its financial covenant requirements, it would need to obtain waivers or consents under the Senior Secured Credit Facilities; however, the Authority can provide no assurance that it would be able to obtain such waivers or consents. If the Authority is unable to obtain such waivers or consents, it would be in default under its Senior Secured Credit Facilities, which may result in cross-defaults under its other outstanding indebtedness and allow its lenders and creditors to exercise their rights and remedies as defined under their respective agreements, including their right to accelerate the repayment of the Authority's outstanding indebtedness. If such acceleration were to occur, the Authority can provide no assurance that it would be able to obtain the financing necessary to repay such accelerated indebtedness.
	Senior Unsecured Notes
	2013 9 3/4% Senior Unsecured Notes
	In August 2013, the Authority issued $500.0 million Senior Unsecured Notes with fixed interest payable at a rate of 9.75% per annum (the “2013 Senior Unsecured Notes”). The 2013 Senior Unsecured Notes mature on September 1, 2021. The Authority may redeem the 2013 Senior Unsecured Notes, in whole or in part, at any time prior to September 1, 2016 at a price equal to 100% of the principal amount plus a make-whole premium and accrued interest to the date of redemption. On or after September 1, 2016, the Authority may redeem the 2013 Senior Unsecured Notes, in whole or in part, at specified redemption prices, together with accrued interest to the date of redemption. If the Authority experiences specific kinds of change of control triggering events, the Authority must offer to repurchase the 2013 Senior Unsecured Notes at a price equal to 101% of the principal amount thereof, plus accrued interest to the purchase date. In addition, if the Authority undertakes certain types of asset sales and does not use the related sale proceeds for specified purposes, the Authority may be required to offer to repurchase the 2013 Senior Unsecured Notes at a price equal to 100% of the principal amount, plus accrued interest. Interest on the 2013 Senior Unsecured Notes is payable semi-annually on March 1st and September 1st. On March 11, 2014, the Authority completed an offer to exchange the 2013 Senior Unsecured Notes for a new issue of substantially identical debt securities registered under the Securities Act of 1933, with all outstanding notes being exchanged. As of March 31, 2015 and September 30, 2014, accrued interest on the 2013 Senior Unsecured Notes was $4.1 million.
	The 2013 Senior Unsecured Notes are uncollateralized general obligations of the Authority and are effectively subordinated to all of the Authority’s and the Guarantors' and future guarantor subsidiaries' senior secured indebtedness, including the Senior Secured Credit Facilities, to the extent of the value of the collateral securing such indebtedness. The 2013 Senior Unsecured Notes also are effectively subordinated to any indebtedness and other liabilities (including trade payables) of the Authority’s subsidiaries that do not guarantee the 2013 Senior Unsecured Notes. The 2013 Senior Unsecured Notes rank equally in right of payment with the Authority’s other unsecured, unsubordinated indebtedness, including trade payables. The 2013 Senior Unsecured Notes are fully and unconditionally guaranteed, jointly and severally, by the Guarantors.
	The 2013 Senior Unsecured Notes indenture contains certain covenants that, subject to certain significant exceptions, limit, among other things, the Authority’s and Guarantors’ ability to incur additional debt, pay dividends or distributions, make certain investments, create liens on assets, enter into transactions with affiliates, merge or consolidate with another company or transfer and sell assets. The 2013 Senior Unsecured Notes indenture includes customary events of default, including, but not limited to, failure to make required payments, failure to comply with certain agreements or covenants, failure to pay certain other indebtedness, the occurrence of which is caused by a failure to pay principal, premium or interest or results in the acceleration of such indebtedness, certain events of bankruptcy and insolvency and certain judgment defaults.
	Senior Subordinated Notes
	2005 6 7/8% Senior Subordinated Notes
	In February 2005, the Authority issued $150.0 million Senior Subordinated Notes with fixed interest payable at a rate of 6.875% per annum (the “2005 Senior Subordinated Notes”). In March 2012, the Authority completed a private exchange offer and consent solicitation for any or all of its outstanding 2005 Senior Subordinated Notes. As part of the exchange offer, the Authority solicited and received consents from tendering holders to certain amendments to the indentures governing the 2005 Senior Subordinated Notes, which eliminated certain covenants under the notes and related indenture. The aggregate principal amount of 2005 Senior Subordinated Notes tendered and exchanged was $140.3 million. Subsequent to the Authority's March 2012 private exchange offer, $9.7 million of the 2005 Senior Subordinated Notes remained outstanding, which amount, including accrued interest, was repaid at maturity on February 15, 2015 with cash on hand and drawings under the Revolving Facility.

	2012 11% Senior Subordinated Notes
	In March 2012, the Authority issued $344.2 million Senior Subordinated Toggle Notes with fixed interest payable at a rate of 11% per annum (the “2012 Senior Subordinated Notes”) in exchange for $203.8 million of the Authority's then outstanding 2004 7 1/8% Senior Subordinated Notes and $140.3 million of 2005 Senior Subordinated Notes. The 2012 Senior Subordinated Notes mature on September 15, 2018. The Authority may redeem the 2012 Senior Subordinated Notes, in whole or in part, at any time, at a price equal to 100% of the principal amount plus accrued interest. If a change of control of the Authority occurs, the Authority must offer to repurchase the 2012 Senior Subordinated Notes at a price equal to 101% of the principal amount, plus accrued interest. In addition, if the Authority undertakes certain types of asset sales or suffers events of loss, and the Authority does not use the related sale or insurance proceeds for specified purposes, the Authority may be required to offer to repurchase the 2012 Senior Subordinated Notes at a price equal to 100% of the principal amount, plus accrued interest. Interest on the 2012 Senior Subordinated Notes is payable semi-annually on March 15th and September 15th. The initial interest payment on the 2012 Senior Subordinated Notes was payable entirely in cash. For any subsequent interest payment period through March 15, 2018, the Authority may, at its option, elect to pay interest on the 2012 Senior Subordinated Notes either entirely in cash or by paying up to 2% in 2012 Senior Subordinated Notes (“PIK Interest”). If the Authority elects to pay PIK Interest, such election will increase the principal amount of the 2012 Senior Subordinated Notes in an amount equal to the amount of PIK Interest for the applicable interest payment period to holders of 2012 Senior Subordinated Notes on the relevant record date.
	In August 2013, the Authority repurchased an aggregate principal amount of $69.0 million 2012 Senior Subordinated Notes.

	The 2012 Senior Subordinated Notes and guarantees have not been and will not be registered under the Securities Act of 1933 or the securities laws of any other jurisdiction and may not be offered or sold in the United States absent registration or an applicable exemption from such registration requirements.
	The Authority's senior subordinated notes are uncollateralized general obligations of the Authority and are subordinated to borrowings under the Senior Secured Credit Facilities and 2013 Senior Unsecured Notes. The senior subordinated notes are fully and unconditionally guaranteed, jointly and severally, by the Guarantors.
	The senior and senior subordinated note indentures contain certain non-financial and financial covenant requirements with which the Authority and the Tribe must comply. The non-financial covenant requirements include, among other things, reporting obligations, compliance with laws and regulations, maintenance of licenses and insurances and continued existence of the Authority. The financial covenant requirements include, among other things, subject to certain exceptions, limitations on the Authority's and the Guarantors' ability to incur additional indebtedness, pay dividends or distributions, make certain investments, create liens on assets, enter into transactions with affiliates, merge or consolidate with another company, transfer or sell assets or impair assets constituting collateral.
	As of March 31, 2015, the Authority and the Tribe were in compliance with all respective covenant requirements under the senior and senior subordinated note indentures.
	The Authority or its affiliates may, from time to time, seek to purchase or otherwise retire outstanding indebtedness for cash in open market purchases, privately negotiated transactions or otherwise. Any such transaction will depend on prevailing market conditions and the Authority's liquidity and covenant requirement restrictions, among other factors.
	Line of Credit
	In November 2013, the Authority entered into a $16.5 million revolving credit facility with Bank of America, N.A. (the “Line of Credit”). The Line of Credit is coterminous with the Senior Secured Credit Facilities. Pursuant to provisions of the Senior Secured Credit Facilities, under certain circumstances, the Line of Credit may be converted into loans under the Senior Secured Credit Facilities. Under the Line of Credit, each advance accrues interest on the basis of a one-month LIBOR Rate plus an applicable margin based on the Authority's total leverage ratio, as each term is defined under the Line of Credit. As of March 31, 2015, amounts outstanding under the Line of Credit totaled $413,000. Borrowings under the Line of Credit are uncollateralized obligations. The Line of Credit contains negative covenants and financial maintenance covenants that are substantially the same as those contained in the Senior Secured Credit Facilities. As of March 31, 2015, the Authority was in compliance with all covenant requirements under the Line of Credit. As of March 31, 2015 and September 30, 2014, accrued interest on the Line of Credit was $22,000 and $23,000, respectively.

For each 12-month period commencing July 1, 1995, Slot Win Contribution payments shall be the lesser of: (1) 30% of gross revenues from slot machines or (2) the greater of (a) 25% of gross revenues from slot machines or (b) $80.0 million.
	In September 2009, the Authority entered into a settlement agreement with the State of Connecticut regarding contribution payments on the Authority's free promotional slot play program. Under the terms of the settlement agreement, effective July 1, 2009, the State of Connecticut agreed that no value shall be attributed to free promotional slot plays utilized by patrons at Mohegan Sun for purposes of calculating monthly contribution payments, provided that the aggregate amount of free promotional slot plays during any month does not exceed a certain threshold of gross revenues from slot machines for such month. In the event free promotional slot plays granted by the Authority exceed such threshold, contribution payments are required on such excess face amount of free promotional slot plays at the same rate as Slot Win Contribution payments, or 25%. The threshold before contribution payments on free promotional slot plays are required is currently 11% of gross revenues from slot machines.
	The Authority reflected expenses associated with the combined Slot Win Contribution and free promotional slot play contribution totaling $34.3 million and $34.7 million for the three months ended March 31, 2015 and 2014, respectively, and $70.8 million and $71.0 million for the six months ended March 31, 2015 and 2014, respectively. As of March 31, 2015 and September 30, 2014, the combined outstanding Slot Win Contribution and free promotional slot play contribution totaled $12.8 million and $11.6 million, respectively.
	Pennsylvania Slot Machine Tax
	Downs Racing holds a Category One slot machine license issued by the Pennsylvania Gaming Control Board (the “PGCB”) for the operation of slot machines at Mohegan Sun Pocono. This license permits Downs Racing to install and operate up to 3,000 slot machines at Mohegan Sun Pocono, expandable to up to a total of 5,000 slot machines upon request and approval of the PGCB.
	The Pennsylvania Race Horse Development and Gaming Act stipulates that holders of Category One slot machine licenses must pay a portion of revenues from slot machines to the PGCB on a daily basis (“Pennsylvania Slot Machine Tax”), which includes local share assessments to be paid to the cities and municipalities hosting Mohegan Sun Pocono and amounts to be paid to the Pennsylvania Harness Horsemen's Association, Inc. (the “PHHA”). The Pennsylvania Slot Machine Tax is currently 55% of gross revenues from slot machines, 2% of which is subject to a $10.0 million minimum annual threshold to ensure that the host cities and municipalities receive an annual minimum of $10.0 million in local share assessments. Downs Racing maintains a $1.5 million escrow deposit in the name of the Commonwealth of Pennsylvania for Pennsylvania Slot Machine Tax payments, which was included in "Other assets, net" in the accompanying condensed consolidated balance sheets.
	The Authority reflected expenses associated with the Pennsylvania Slot Machine Tax totaling $28.4 million and $30.6 million for the three months ended March 31, 2015 and 2014, respectively, and $57.6 million and $60.4 million for the six months ended March 31, 2015 and 2014, respectively. As of March 31, 2015 and September 30, 2014, outstanding Pennsylvania Slot Machine Tax payments totaled $1.9 million and $4.6 million, respectively.
	Pennsylvania Table Game Tax
	In January 2010, the Commonwealth of Pennsylvania amended the Pennsylvania Race Horse Development and Gaming Act to allow slot machine operators in the Commonwealth of Pennsylvania to obtain a table game operation certificate and operate certain table games, including poker. Under the amended law, holders of table game operation certificates must pay a portion of revenues from table games to the PGCB on a weekly basis (“Pennsylvania Table Game Tax”). The Pennsylvania Table Game Tax is currently 12%, plus the 2% local share assessments.
	The Authority reflected expenses associated with the Pennsylvania Table Game Tax totaling $1.8 million and $1.5 million for the three months ended March 31, 2015 and 2014, respectively, and $3.4 million and $3.0 million for the six months ended March 31, 2015 and 2014, respectively. As of March 31, 2015 and September 30, 2014, outstanding Pennsylvania Table Game Tax payments totaled $198,000 and $156,000, respectively.
	Pennsylvania Regulatory Fee
	Slot machine licensees in the Commonwealth of Pennsylvania are required to reimburse state gaming regulatory agencies for various administrative and operating expenses (“Pennsylvania Regulatory Fee”) at a rate of 1.5% of gross revenues from slot machines and table games.
	The Authority reflected expenses associated with the Pennsylvania Regulatory Fee totaling $1.1 million and $1.2 million for the three months ended March 31, 2015 and 2014, respectively, and $2.2 million and $2.3 million for the six months ended March 31, 2015 and 2014, respectively. As of March 31, 2015 and September 30, 2014, outstanding Pennsylvania Regulatory Fee payments to the PGCB totaled $171,000 and $147,000, respectively.
	Pennsylvania Gaming Control Board Loans
	The PGCB was initially granted $36.1 million in loans to fund start-up costs for gaming in the Commonwealth of Pennsylvania, which are to be repaid by slot machine licensees (the "Initial Loans"). The PGCB was subsequently granted an additional $63.8 million in loans to fund ongoing gaming oversight costs, which also are to be repaid by slot machine licensees (the "Subsequent Loans"). Repayment of the Initial Loans will commence when all 14 authorized gaming facilities are opened in the Commonwealth of Pennsylvania. Currently, 12 of the 14 authorized gaming facilities have commenced operations. As of March 31, 2015, the Authority has concluded that a repayment contingency for the Initial Loans is probable but not reasonably estimable since the PGCB has not yet established a method of assessment of repayment for the Initial Loans and, as such, the Authority has not recorded a related accrual for such repayment. In June 2011, the PGCB adopted a method of assessment of repayment for the Subsequent Loans pursuant to which repayment commenced on January 1, 2012 and will continue over a 10-year period in accordance with a formula based on a combination of a single fiscal year and cumulative gross revenues from slot machines for each operating slot machine licensee.
	The Authority reflected expenses associated with this repayment schedule totaling $156,000 and $160,000 for the three months ended March 31, 2015 and 2014, respectively, and $313,000 and $320,000 for the six months ended March 31, 2015 and 2014, respectively.
	Horsemen’s Agreement
	Downs Racing and the PHHA are parties to an agreement that governs all live harness racing and simulcasting and account wagering at the Pennsylvania Facilities through December 31, 2015. As of March 31, 2015 and September 30, 2014, outstanding payments to the PHHA for purses earned by horsemen, but not yet paid, and other fees totaled $6.7 million and $8.1 million, respectively.
	Priority Distribution Agreement
	In August 2001, the Authority and the Tribe entered into an agreement (the “Priority Distribution Agreement”), which stipulates that the Authority must make monthly payments to the Tribe to the extent of the Authority's Net Cash Flow as defined under the Priority Distribution Agreement. The Priority Distribution Agreement was amended as of December 31, 2014. As amended, the Priority Distribution Agreement, which has a perpetual term, limits the minimum aggregate priority distribution payments in each calendar year to $40.0 million. Payments under the Priority Distribution Agreement: (1) do not reduce the Authority's obligations to reimburse the Tribe for governmental and administrative services provided by the Tribe or to make payments under any other agreements with the Tribe, (2) are limited obligations of the Authority and are payable only to the extent of the Authority's Net Cash Flow as defined under the Priority Distribution Agreement and (3) are not secured by a lien or encumbrance on any of the Authority's assets or properties.
	The Authority reflected payments associated with the Priority Distribution Agreement totaling $6.6 million and $4.9 million for the three months ended March 31, 2015 and 2014, respectively, and $11.5 million and $9.7 million for the six months ended March 31, 2015 and 2014, respectively.
	Litigation
	The Authority is a defendant in various litigation matters resulting from its normal course of business. In management's opinion, the aggregate liability, if any, arising from such litigations will not have a material impact on the Authority's financial position, results of operations or cash flows.

RELINQUISHMENT AGREEMENT	6 Months Ended

RELINQUISHMENT AGREEMENT [Abstract]
RELINQUISHMENT AGREEMENT	RELINQUISHMENT AGREEMENT:
	In February 1998, the Authority and Trading Cove Associates (“TCA”) entered into a relinquishment agreement (the “Relinquishment Agreement”). Effective January 1, 2000, the Relinquishment Agreement superseded a then-existing management agreement with TCA requiring, among other things, that the Authority make certain payments to TCA out of, and determined as a percentage of, Revenues, as defined under the Relinquishment Agreement, generated by Mohegan Sun over a 15-year period. The Authority, in accordance with authoritative guidance issued by the FASB pertaining to the accounting for contingencies, recorded a $549.1 million relinquishment liability at September 30, 1998 based on the estimated present value of its obligations under the Relinquishment Agreement. The Relinquishment Agreement expired on December 31, 2014. As of March 31, 2015, no amount was outstanding under the Relinquishment Agreement. As of September 30, 2014, the carrying amount of the relinquishment liability was $25.2 million. The decrease in the relinquishment liability during the six months ended March 31, 2015 was due to $25.2 million in relinquishment payments and a $243,000 relinquishment liability reassessment credit. This reduction in the relinquishment liability was offset by $227,000 representing the accretion of discount to the relinquishment liability.
	Relinquishment payments consisted of the following (in millions):
		For the Six Months Ended
		March 31, 2015		March 31, 2014
	Principal	$	24.4	$	23.5
	Accretion of discount	0.8		1.8
	Total	$	25.2	$	25.3
	The accretion of discount to the relinquishment liability reflects the accretion of the discount to the present value of the relinquishment liability for the impact of the time value of money. As of March 31, 2015, no relinquishment payment was earned but unpaid. As of September 30, 2014, relinquishment payments earned but unpaid were $13.2 million.

COWLITZ_PROJECT

COWLITZ PROJECT (Cowlitz Project)	6 Months Ended

Cowlitz Project
Schedule of Long-term Development Projects [Line Items]
COWLITZ PROJECT	COWLITZ PROJECT:
	In September 2004, Salishan-Mohegan entered into development and management agreements with the Cowlitz Tribe in connection with the Cowlitz Project, which agreements have been amended from time to time. Under the terms of the development agreement, Salishan-Mohegan will assist in securing financing, as well as administer and oversee the planning, designing, development, construction and furnishing of the proposed casino. The development agreement provides for development fees of 3% of total project costs, as defined under the development agreement. Under the terms of Salishan-Mohegan's operating agreement, development fees will be distributed to Mohegan Ventures-NW. In 2006, pursuant to the development agreement, Salishan-Mohegan purchased an approximately 152-acre site for the proposed casino.
	Under the terms of the management agreement, Salishan-Mohegan will manage, operate and maintain the proposed casino for a period of seven years following its opening. The management agreement provides for management fees of 24% of net revenues, as defined under the management agreement, which approximates net income earned from the Cowlitz Project. Under the terms of Salishan-Mohegan’s operating agreement, management fees will be allocated to the members of Salishan-Mohegan based on their respective membership interests. The management agreement is subject to approval by the National Indian Gaming Commission. On August 7, 2014, the Cowlitz Tribe’s Class III Tribal-State gaming compact with the State of Washington became effective with notice of federal approval published in the Federal Register. According to the notice, the compact allows for two gaming facilities, allocates 975 gaming machines for leasing, authorizes the operation of up to 3,000 gaming machines and 125 table games, and is in effect until terminated by written agreement of both parties.
	Under the terms of the development agreement, certain receivables contributed to Salishan-Mohegan and amounts advanced by Salishan-Mohegan on behalf of the Cowlitz Tribe are reimbursable to Salishan-Mohegan by the Cowlitz Tribe, subject to appropriate approvals defined under the development agreement. Reimbursements are contingent and are to be distributed upon: (1) the receipt of necessary financing for the development of the proposed casino and (2) the related property being taken into trust by the United States Department of the Interior. The Authority currently accrues interest on the Salishan-Mohegan receivables at an annual rate of 10.0%.
	In March 2013, two lawsuits challenging a December 2010 decision of the Assistant Secretary - Indian Affairs of the Department of the Interior to take the Cowlitz Project site into trust were dismissed on procedural grounds. In April 2013, pursuant to judicial directive, the Department of the Interior issued a new Record of Decision to take the Cowlitz Project site into trust, determining for a second time that the site will serve as the initial reservation of the Cowlitz Tribe and that the tribe may conduct gaming on such lands under the Indian Gaming Regulatory Act. In June 2013, the plaintiffs in the earlier litigation filed two new lawsuits challenging the new Record of Decision, and, in July 2013, those lawsuits were consolidated. By Notice of Trust Acquisition filed with the court on October 22, 2014, while motions for summary judgment filed by the plaintiffs and the defendants were pending, the federal defendants provided the court notice of the United States Department of the Interior’s planned trust acquisition of the Cowlitz Project site, which was the subject of the litigation, on the earlier of: (1) January 21, 2015 and (2) 30 days after a court order granting summary judgment in favor of the federal defendants. On December 12, 2014, a U.S. District Court for the District of Columbia judge entered an order granting summary judgment in favor of the federal defendants, thereby upholding the Record of Decision and denying the federal plaintiffs’ motion. In December 2014 and February 2015, the plaintiffs filed separate appeals to the Court of Appeals for the District of Columbia Circuit. In February 2015, those appeals were consolidated by the Court of Appeals.
	On March 10, 2015, the Cowlitz Project site was taken into trust by the United States Department of the Interior for the benefit of the Cowlitz Tribe. In connection with this event, the Cowlitz Tribe leased a substantial portion of the Cowlitz Project site back to Salishan-Mohegan for a nominal rental fee. The initial term of the lease is 25 years with an option to extend the term for two additional 25-year periods. Under the lease, upon financing of the Cowlitz Project, Salishan-Mohegan shall assign the lease to the Cowlitz Tribe. If the Cowlitz Project does not proceed due to a final court determination that the site is not eligible for gaming, upon payment of certain consideration, the Cowlitz Tribe may purchase the leasehold interest in the premises and terminate the lease.
	The carrying value of the land totaling approximately $20.0 million, which was included in property and equipment, net, in the accompanying condensed consolidated balance sheet as of September 30, 2014, was transferred to the Cowlitz Tribe at the time the site was taken into trust. This transfer resulted in an additional long-term receivable due from the Cowlitz Tribe as permitted under the development agreement, and was included in other assets, net, in the accompanying condensed consolidated balance sheet as of March 31, 2015.
	Development of the Cowlitz Project remains subject to certain remaining governmental and regulatory approvals and agreements. The Authority can provide no assurance that the remaining steps and conditions for the Cowlitz Project site to be approved for gaming will be satisfied or that necessary financing for the development of the proposed casino will be obtained. Furthermore, the Authority can provide no assurance as to the outcome of the pending federal court appeal or any future litigation relating to the Cowlitz Project. Please refer to the Authority’s Annual Report on Form 10-K for the fiscal year ended September 30, 2014 and its other reports and filings with the SEC for further information and details regarding the Cowlitz Project.

Segment Reporting [Abstract]
SEGMENT REPORTING	SEGMENT REPORTING:
	As of March 31, 2015, the Authority owns and operates, either directly or through wholly-owned subsidiaries, Mohegan Sun, the Connecticut Sun franchise and the Mohegan Sun Golf Club, and has partnered with an unrelated third-party to own and operate the New England Black Wolves franchise (collectively, the “Connecticut Facilities”), and the Pennsylvania Facilities. Substantially all of the Authority's revenues are derived from these operations. The Connecticut Sun franchise, the Mohegan Sun Golf Club and the New England Black Wolves franchise are aggregated with the Mohegan Sun operating segment because these operations all share similar economic characteristics, which is to generate gaming and entertainment revenues by attracting patrons to Mohegan Sun. The Authority's executive officers review and assess the performance and operating results and determine the proper allocation of resources to the Connecticut Facilities and the Pennsylvania Facilities on a separate basis. Accordingly, the Authority has two separate reportable segments: (1) Mohegan Sun, which includes the operations of the Connecticut Facilities and (2) Mohegan Sun Pocono, which includes the operations of the Pennsylvania Facilities. The Authority's operations related to investments in unconsolidated affiliates and certain other Corporate and management operations have not been identified as separate reportable segments; therefore, these operations are included in Corporate and other in the following segment disclosures to reconcile to consolidated results.

BASIS_OF_PRESENTATION_Policies

BASIS OF PRESENTATION (Policies)	6 Months Ended
	Mar. 31, 2015
Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with instructions to Form 10-Q and Rule 10-01 of Regulation S-X. In accordance with Rule 10-01, the accompanying unaudited condensed consolidated financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete consolidated financial statements. The accompanying year-end condensed consolidated balance sheet was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. In management's opinion, all adjustments, including normal recurring accruals and adjustments, necessary for a fair statement of the Authority's operating results for the interim period, have been included. In addition, certain amounts in the accompanying 2014 supplemental condensed consolidating financial statements have been reclassified to conform to the 2015 presentation.
	The gaming market in the Northeastern United States is seasonal in nature, with peak gaming activities often occurring at Mohegan Sun and Mohegan Sun Pocono during the months of May through August. Accordingly, the Authority's operating results for the three months and six months ended March 31, 2015 are not necessarily indicative of operating results for other interim periods or an entire fiscal year.
	The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Authority's Annual Report on Form 10-K for the fiscal year ended September 30, 2014.
Principles of Consolidation	Principles of Consolidation
	The accompanying condensed consolidated financial statements include the accounts of the Authority and its majority and wholly-owned subsidiaries and entities. In accordance with authoritative guidance issued by the Financial Accounting Standards Board (the “FASB”) pertaining to consolidation of variable interest entities, the accounts of Salishan-Mohegan are consolidated into the accounts of Mohegan Ventures-NW and the accounts of NEBW are consolidated into the accounts of Mohegan Lacrosse as Mohegan Ventures-NW and Mohegan Lacrosse are deemed to be the primary beneficiaries. In consolidation, all inter-company balances and transactions were eliminated.
Fair Value of Financial Instruments	Fair Value of Financial Instruments
	The fair value amounts presented below are reported to satisfy disclosure requirements pursuant to authoritative guidance issued by the FASB pertaining to disclosures about fair values of financial instruments and are not necessarily indicative of amounts that the Authority could realize in a current market transaction.
	The Authority applies the following fair value hierarchy, which prioritizes the inputs utilized to measure fair value into three levels:
	•	Level 1 - Quoted prices for identical assets or liabilities in active markets;
	•	Level 2 - Quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in inactive markets or valuations based on models where the significant inputs are observable or can be corroborated by observable market data; and
	•	Level 3 - Valuations based on models where the significant inputs are unobservable. The unobservable inputs reflect the Authority's estimates or assumptions that market participants would utilize in pricing such assets or liabilities.
	The Authority's assessment of the significance of a particular input requires judgment and may affect the valuation of financial assets and liabilities and their placement within the fair value hierarchy.
New Accounting Pronouncements	New Accounting Standards
	In May 2014, the FASB issued an accounting standard update on revenue recognition that will be applied to all contracts with customers. The update requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. It also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. This guidance will be required to be applied on a retrospective basis, using one of two methodologies, and will be effective for annual reporting periods beginning after December 15, 2016, with early application not being permitted. However, in April 2015, the FASB issued proposed guidance that would defer the effective date by one year. The Authority is currently evaluating the impact that this guidance will have on its financial position and results of operations.
	In August 2014, the FASB issued an accounting standard update which provides guidance on determining when and how to disclose going concern uncertainties in the financial statements. The update requires management to perform interim and annual assessments of an entity's ability to continue as a going concern within one year of the date the financial statements are issued. It also requires management to provide certain disclosures if conditions or events raise substantial doubt about the entity's ability to continue as a going concern. This guidance will be required for annual reporting periods ending after December 15, 2016, and interim reporting periods thereafter, with early application permitted. The Authority is currently evaluating the impact that this guidance will have on its financial position and results of operations.
	In February 2015, the FASB issued an accounting standards update which amends existing requirements applicable to reporting entities that are required to evaluate whether certain legal entities should be consolidated. This guidance will be required to be applied either on a retrospective or modified retrospective basis and will be effective for annual reporting periods beginning after December 15, 2015, and interim reporting periods thereafter, with early application permitted. The Authority is currently evaluating the impact that this guidance will have on its financial position and results of operations.
	In April 2015, the FASB issued an accounting standard update to clarify the required presentation of debt issuance costs. The update requires that debt issuance costs be presented in the balance sheet as a direct reduction from the carrying amount of the related debt liability rather than as an asset. This guidance will be required to be applied on a retrospective basis and will be effective for annual reporting periods beginning after December 15, 2015, and interim reporting periods thereafter, with early application permitted. The Authority is currently evaluating the impact that this guidance will have on its financial position and results of operations.
