LETTER FROM THE CHAIRMAN

Dear Shareholder:

This  semiannual  report  for  Dreyfus  BASIC  U.S. Government Money Market Fund
covers the six-month period from March 1, 2003, through August 31, 2003. Inside,
you'll  find  valuable  information  about  how the fund was managed during the
reporting  period,  including  a  discussion  with the fund's portfolio manager,
Thomas S. Riordan.

After a prolonged period of sluggish growth, the U.S. economy has shown signs of
sustainable  improvement.  Estimates of economic growth in 2003's second quarter
recently  were revised upward to 3.3%, and many economists expect another strong
showing  for  the third quarter. At the same time, the Federal Reserve Board has
reaffirmed  its  commitment  to keeping interest rates near today's historically
low levels. Therefore, we expect money market yields to remain relatively stable
for the foreseeable future.

We  believe  that  it  is  important for investors to remember that money market
funds  have  continued  to  achieve  their primary objective of preserving their
shareholders'  capital. For emergency reserves and money earmarked for near-term
needs,  we believe that money market funds remain a sound investment. As always,
we encourage you to talk with your financial advisor about investment challenges
and opportunities as market conditions evolve.

Thank you for your continued confidence and support.

Sincerely,


/S/STEPHEN E. CANTER
Stephen E. Canter
Chairman and Chief Executive Officer
The Dreyfus Corporation

DISCUSSION OF FUND PERFORMANCE

Thomas S. Riordan, Portfolio Manager

How did Dreyfus BASIC U.S. Government Money Market Fund perform during the
period?

For  the six-month period ended August 31, 2003, the fund produced an annualized
yield  of  0.82%  and,  taking  into  account  the  effects  of  compounding, an
annualized effective yield of 0.82%.(1)

WHAT IS THE FUND'S INVESTMENT APPROACH?

The  fund  seeks  as  high  a  level of current income as is consistent with the
preservation  of capital and the maintenance of liquidity. The fund invests only
in  securities  issued  or  guaranteed  as to interest and principal by the U.S.
government, its agencies and instrumentalities, as well as repurchase agreements
backed by such obligations.

When  managing  the fund, we closely monitor the outlook for economic growth and
inflation,  follow overseas developments and consider the posture of the Federal
Reserve  Board  (the  "Fed" ) in  our decisions as to how to structure the fund.
Based  upon our economic outlook, we actively manage the fund's average maturity
in  looking  for  opportunities that may present themselves in light of possible
changes in interest rates.

WHAT OTHER FACTORS INFLUENCED THE FUND'S PERFORMANCE?

The U.S. economy  continued to struggle when the reporting period began, as
evidenced  by the first  quarter of 2003's  annualized  GDP growth  rate of just
1.4%.  Previous hopes of a more robust economic  rebound faded as mounting fears
of war caused  consumer  confidence  to fall to new lows.  In fact, at its March
meeting,  the Fed indicated that uncertainty  regarding the war with Iraq was so
great that it could not adequately assess prevailing  economic risks. Later that
month, however, investors became more optimistic as it became clearer that major
combat in Iraq  would be over  quickly.  Yields of  short-term  U.S.  government
securities began to rise at the longer end of the curve as investors'  attention
returned to the prospects for the U.S. economy.

                                                             The Fund


DISCUSSION OF FUND PERFORMANCE (CONTINUED)

In  May,  the  economy  began  to  show  signs of sustainable improvement. A key
purchasing  index  rose  significantly,  suggesting  better  conditions  in  the
manufacturing sector, and consumer confidence rebounded. These encouraging signs
were  supported  by  gains  in  the  stock market, low inflation, moderating oil
prices,  rising  productivity  and  pending tax cuts. However, at its meeting in
early  May,  the Fed adopted a relatively cautious stance, saying economic risks
were "weighted toward weakness for the foreseeable future."

Economic  indicators  continued  to improve in June, including stronger consumer
confidence  and  robust existing and new home sales. It was later estimated that
U.S.  GDP expanded at a higher than expected 2.4% annualized rate for the second
quarter  of  2003. On the other hand, the unemployment rate climbed to 6.4%, its
highest  level  in nine years, suggesting that the impending recovery might be a
relatively    jobless    one.

Because  of  the  remote  possibility  that  deflationary  forces might derail a
potential  economic recovery, most investors expected the Fed to reduce interest
rates  further  at  its  meeting  in late June. The Fed did not disappoint them,
lowering  the federal funds rate another 25 basis points to 1%. However, because
the  Fed  did  not  cut rates by 50 basis points as some investors had expected,
money market yields rose in the wake of the Fed's announcement.

In  July, the ISM Manufacturing Index expanded for the first time since February
2003,  rising  to  a  point  that  most  analysts consider to be an indicator of
economic  expansion.  However,  prices of longer-term U.S. government securities
plunged  amid  concerns  that  higher  mortgage  rates  might constrain consumer
spending  and  stall the economic recovery, and a rising supply of U.S. Treasury
securities put additional downward pressure on prices.


In August, it became clearer that business investment and consumer spending were
rebounding,  even  as inflation remained well under control. Other data released
in  August  indicated  that  the  pace  of layoffs was stabilizing, and consumer
confidence  was  rising.  In  the  money  markets,  yields  rose  modestly among
securities  with  very  short  maturities,  but  longer-term  yields  came under
pressure following the month's positive economic news.

WHAT IS THE FUND'S CURRENT STRATEGY?

We  believe  that the Fed will most likely keep short-term interest rates at the
benchmark  rate  of  1%  for  some  time. In addition, the yield curve steepened
during  the summer after being inverted at times during the spring. Accordingly,
we  generally  have  maintained  the fund's weighted average maturity toward the
long end of its range. This strategy is designed to capture incrementally higher
yields  at  the  longer  end  of  the curve should those opportunities arise. Of
course,  we  intend  to monitor economic and market trends carefully, and we may
make changes to our strategies as conditions evolve.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1--SIGNIFICANT ACCOUNTING POLICIES:

Dreyfus BASIC U.S. Government Money Market Fund (the "fund") is registered under
the  Investment  Company  Act  of 1940, as amended (the "Act"), as a diversified
open-end  management  investment  company. The fund's investment objective is to
provide  investors  with as high a level of current income as is consistent with
the  preservation  of  capital  and  the  maintenance  of liquidity. The Dreyfus
Corporation (the "Manager") serves as the fund's investment adviser. The Manager
is  a  wholly-owned  subsidiary  of  Mellon  Bank, N.A., which is a wholly-owned
subsidiary   of   Mellon  Financial  Corporation  (" Mellon" ). Dreyfus  Service
Corporation  (the  "Distributor"), a wholly-owned subsidiary of the Manager, is
the  distributor  of  the  fund's shares, which are sold to the public without a
sales charge.

It  is  the  fund's policy to maintain a continuous net asset value per share of
$1.00; the fund has adopted certain investment, portfolio valuation and dividend
and distribution policies to enable it to do so. There is no assurance, however,
that  the  fund  will  be able to maintain a stable net asset value per share of
$1.00.

The  fund' s  financial  statements  are  prepared in accordance with accounting
principles generally accepted in the United States, which may require the use of
management  estimates  and  assumptions.  Actual results could differ from those
estimates.

(A)  PORTFOLIO VALUATION: Investments in securities are valued at amortized cost
in accordance with Rule 2a-7 of the Act, which has been determined by the fund's
Board of Trustees to represent the fair value of the fund's investments.

(B)  SECURITIES  TRANSACTIONS AND INVESTMENT INCOME: Securities transactions are
recorded  on  a  trade  date  basis.  Realized  gain  and  loss  from securities
transactions  are  recorded  on  the  identified  cost  basis.  Interest income,
adjusted for amortization of discount and premium on investments, is earned from
settlement  date  and  is  recognized  on the accrual basis. Cost of investments
represents  amortized  cost.  Under the terms of the custody agreement, the fund
receives net earnings credits based on available cash balances left on deposit.

                                                             The Fund

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

The  fund  may  enter  into  repurchase  agreements, with financial institutions
deemed  to  be  creditworthy  by  the  fund' s  Manager, subject to the seller's
agreement  to repurchase and the fund's agreement to resell such securities at a
mutually   agreed   upon  price.  Securities  purchased  subject  to  repurchase
agreements are deposited with the fund's custodian and, pursuant to the terms of
the  repurchase  agreement,  must have an aggregate market value greater than or
equal  to  the repurchase price plus accrued interest at all times. If the value
of  the underlying securities falls below the value of the repurchase price plus
accrued  interest,  the  fund  will  require  the  seller  to deposit additional
collateral by the next business day. If the request for additional collateral is
not met, or the seller defaults on its repurchase obligation, the fund maintains
the  right  to  sell the underlying securities at market value and may claim any
resulting loss against the seller.

(C) DIVIDENDS TO SHAREHOLDERS: It is the policy of the fund to declare dividends
daily  from  investment  income-net.  Such dividends are paid monthly. Dividends
from net realized capital gain, if any, are normally declared and paid annually,
but  the fund may make distributions on a more frequent basis to comply with the
distribution  requirements of the Internal Revenue Code of 1986, as amended (the
" Code" ). To the extent that net realized capital gain can be offset by capital
loss carryovers, it is the policy of the fund not to distribute such gain.

On  September 2, 2003, the fund declared a cash dividend of approximately $.0001
per  share  from  undistributed  investment income-net which includes investment
income-net for Saturday August 30, 2003 and for Sunday August 31, 2003.

(D) FEDERAL INCOME TAXES: It is the policy of the fund to continue to qualify as
a  regulated  investment company, if such qualification is in the best interests
of  its  shareholders,  by complying with the applicable provisions of the Code,
and  to  make  distributions  of  taxable  income  sufficient to relieve it from
substantially all federal income and excise taxes.

The  fund  has an unused capital loss carryover of $29,815 available for federal
income tax purposes to be applied against future net securitie

profits,  if any, realized subsequent to February 28, 2003. If not applied, $496
of the carryover expires in fiscal 2007, $429 expires in fiscal 2008 and $28,890
expires in fiscal 2011.

The  tax  character of distributions paid to shareholders during the fiscal year
ended  February  28, 2003 were all ordinary income. The tax character of current
year distributions will be determined at the end of the current fiscal year.

At  August 31, 2003, the cost of investments for federal income tax purposes was
substantially  the  same  as  the cost for financial reporting purposes (see the
Statement of Investments).

NOTE 2--MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES:

(A)  Pursuant  to  a  management  agreement  ("Agreement") with the Manager, the
management  fee  is computed at the annual rate of .50 of 1% of the value of the
fund' s  average  daily  net  assets  and  is  payable  monthly. The Manager has
undertaken, until such time as it gives shareholders at least 90 days' notice to
the  contrary,  to  reduce  the  management  fee paid by the fund, if the fund's
aggregate  expenses,  exclusive of taxes, brokerage fees, interest on borrowings
and  extraordinary  expenses, exceed an annual rate of .45 of 1% of the value of
the  fund's average daily net assets, the fund may deduct from the payment to be
made  to  the Manager under the Agreement, or the Manager will bear, such excess
expense.  The reduction in management fee, pursuant to the undertaking, amounted
to $582,791 during the period ended August 31, 2003.

(B)  Under the Shareholder Services Plan, the fund reimburses the Distributor an
amount  not  to  exceed  an  annual rate of .25 of 1% of the value of the fund's
average  daily  net  assets for certain allocated expenses of providing personal
services  and/or  maintaining  shareholder  accounts.  The services provided may
include  personal  services  relating to shareholder accounts, such as answering
shareholder inquiries regarding the fund and providing reports and other informa
The    Fund

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

tion,  and  services  related to the maintenance of shareholder accounts. During
the  period ended August 31, 2003, the fund was charged $193,093 pursuant to the
Shareholder Services Plan.

The  fund  compensates  Dreyfus Transfer, Inc., a wholly-owned subsidiary of the
Manager,   under  a  transfer  agency  agreement  for  providing  personnel  and
facilities  to  perform transfer agency services for the fund. During the period
ended  August  31,  2003,  the fund was charged $48,410 pursuant to the transfer
agency agreement.

(C)  Each  Board  member also serves as a Board member of other funds within the
Dreyfus  complex  (collectively, the "Fund Group"). Each Board member who is not
an  "affiliated person" as defined in the Act receives an annual fee of $25,000,
an  attendance  fee  of $4,000 for each in-person meeting and $500 for telephone
meetings.  The  Chairman  of  the  Board  receives  an  additional  25%  of such
compensation.  Subject to the fund's Emeritus Program Guidelines, Emeritus Board
members, if any, receive 50% of the annual retainer fee and per meeting fee paid
at  the time the Board member achieves emeritus status. These fees are allocated
among  the  funds  in  the  Fund Group in proportion to each fund's relative net
assets.
