MuniYield
California
Fund, Inc.


www.mlim.ml.com


MuniYield California Fund, Inc. seeks to provide shareholders with
as high a level of current income exempt from Federal and California
income taxes as is consistent with its investment policies and
prudent investment management by investing primarily in a portfolio
of long-term municipal obligations the interest on which, in the
opinion of bond counsel to the issuer, is exempt from Federal and
California income taxes.

This report, including the financial information herein, is
transmitted to shareholders of MuniYield California Fund, Inc. for
their information. It is not a prospectus. Past performance results
shown in this report should not be considered a representation of
future performance. The Fund has leveraged its Common Stock and
intends to remain leveraged by issuing Preferred Stock to provide
the Common Stock shareholders with a potentially higher rate of
return. Leverage creates risks for Common Stock shareholders,
including the likelihood of greater volatility of net asset value
and market price of shares of the Common Stock, and the risk that
fluctuations in the short-term dividend rates of the Preferred Stock
may affect the yield to Common Stock shareholders. Statements and
other information herein are as dated and are subject to change.

The Benefits
And Risks of
Leveraging


MuniYield California Fund, Inc. utilizes leveraging to seek to
enhance the yield and net asset value of its Common Stock. However,
these objectives cannot be achieved in all interest rate
environments. To leverage, the Fund issues Preferred Stock, which
pays dividends at prevailing short-term interest rates, and invests
the proceeds in long-term municipal bonds. The interest earned on
these investments is paid to Common Stock shareholders in the form
of dividends, and the value of these portfolio holdings is reflected
in the per share net asset value of the Fund's Common Stock.
However, in order to benefit Common Stock shareholders, the yield
curve must be positively sloped; that is, short-term interest rates
must be lower than long-term interest rates. At the same time, a
period of generally declining interest rates will benefit Common
Stock shareholders. If either of these conditions change, then the
risks of leveraging will begin to outweigh the benefits.

To illustrate these concepts, assume a fund's Common Stock
capitalization of $100 million and the issuance of Preferred
Stock for an additional $50 million, creating a total value of
$150 million available for investment in long-term municipal bonds.
If prevailing short-term interest rates are approximately 3% and
long-term interest rates are approximately 6%, the yield curve has a
strongly positive slope. The fund pays dividends on the $50 million
of Preferred Stock based on the lower short-term interest rates. At
the same time, the fund's total portfolio of $150 million earns the
income based on long-term interest rates. Of course, increases in
short-term interest rates would reduce (and even eliminate) the
dividends on the Common Stock.

In this case, the dividends paid to Preferred Stock shareholders are
significantly lower than the income earned on the fund's long-term
investments, and therefore the Common Stock shareholders are the
beneficiaries of the incremental yield. However, if short-term
interest rates rise, narrowing the differential between short-term
and long-term interest rates, the incremental yield pickup on the
Common Stock will be reduced or eliminated completely. At the same
time, the market value of the fund's Common Stock (that is, its
price as listed on the New York Stock Exchange) may, as a result,
decline. Furthermore, if long-term interest rates rise, the Common
Stock's net asset value will reflect the full decline in the price
of the portfolio's investments, since the value of the fund's
Preferred Stock does not fluctuate. In addition to the decline in
net asset value, the market value of the fund's Common Stock may
also decline.

As a part of its investment strategy, the Fund may invest in certain
securities whose potential income return is inversely related to
changes in a floating interest rate ("inverse floaters"). In
general, income on inverse floaters will decrease when short-term
interest rates increase and increase when short-term interest rates
decrease. Investments in inverse floaters may be characterized as
derivative securities and may subject the Fund to the risks of
reduced or eliminated interest payments and losses of invested
principal. In addition, inverse floaters have the effect of
providing investment leverage and, as a result, the market value of
such securities will generally be more volatile than that of fixed-
rate, tax-exempt securities. To the extent the Fund invests in
inverse floaters, the market value of the Fund's portfolio and the
net asset value of the Fund's shares may also be more volatile than
if the Fund did not invest in these securities.



Swap
Agreements


The Fund may also invest in swap agreements, which are over-the-
counter contracts in which one party agrees to make periodic
payments based on the change in market value of a specified bond,
basket of bonds, or index in return for periodic payments based on a
fixed or variable interest rate or the change in market value of a
different bond, basket of bonds or index. Swap agreements may be
used to obtain exposure to a bond or market without owning or taking
physical custody of securities.



MuniYield California Fund, Inc., April 30, 2003


DEAR SHAREHOLDER


For the six months ended April 30, 2003, the Common Stock of
MuniYield California Fund, Inc. had a net annualized yield of 6.31%,
based on a period-end per share net asset value of $15.52 and $.486
per share income dividends. Over the same period, the total
investment return on the Fund's Common Stock was +6.00%, based on a
change in per share net asset value from $15.14 to $15.52, and
assuming reinvestment of $.486 per share ordinary income dividends.

For the six-month period ended April 30, 2003, the Fund's Auction
Market Preferred Stock had an average yield of 2.43% for Series A,
1.04% for Series B and .74% for Series C.

For a description of the Fund's total investment return based on a
change in the per share market value (as measured by the trading
price of the Fund's shares on the New York Stock Exchange), and
assuming reinvestment of dividends, please refer to the Financial
Highlights section of the Financial Statements included in this
report. As a closed-end fund, the Fund's shares may trade in the
secondary market at a premium or discount to the Fund's net asset
value. As a result, total investment returns based on changes in the
Fund's market value can vary significantly from total investment
return based on changes in the Fund's net asset value.


The Municipal Market Environment
During the six-month period ended April 30, 2003, amid considerable
weekly and monthly volatility, long-term fixed income interest rates
generally declined. Geopolitical tensions and volatile equity
valuations continued to overshadow economic fundamentals as they
have for most of the last 12 months. Reacting to the strong U.S.
equity rally that began last October, fixed income bond yields
remained under pressure in November 2002, as U.S. equity markets
continued to strengthen. During November, the Standard & Poor's 500
(S&P 500) Index rose an additional 5.50%. Equity prices were
supported by further signs of U.S. economic recovery, especially
improving labor market activity. In late November, third-quarter
2002 U.S. gross domestic product growth was 4%, well above the
second-quarter 2002 rate of 1.30%. Financial conditions were also
strengthened by a larger-than-expected reduction in short-term
interest rates by the Federal Reserve Board in early November. The
Federal Funds target rate was lowered 50 basis points (0.50%) to
1.25%, its lowest level since the 1960s. This action by the Federal
Reserve Board was largely viewed as being taken to bolster the
sputtering U.S. economic recovery. Rebounding U.S. equity markets
and the prospects for a more substantial U.S. economic recovery
pushed long-term U.S. Treasury yield levels to 5.10% by late
November.

However, into early 2003, softer equity prices and renewed investor
concerns about U.S. military action against Iraq and North Korea
again pushed bond prices higher. Reacting to disappointing holiday
sales and corporate managements' attempts to scale back analysts'
expectation of future earnings, the S&P 500 Index declined more
than 10% from December 2002 to February 2003. Fearing an eventual
U.S./Iraq military confrontation in 2003, investors again sought the
safety of U.S. Treasury obligations and the prices of fixed income
issues rose. By the end of February 2003, U.S. Treasury bond yields
had declined approximately 40 basis points to 4.67%.

Bond yields continued to fall into early March. Once direct U.S.
military action against Iraq began, bond yields quickly rose. Prior
uncertainty surrounding the Iraqi situation was obviously removed
and early U.S. military successes fostered the hope that the
conflict would be quickly and positively concluded. Concurrently,
the S&P 400 Index rose over 6% as investors, in part, sold fixed
income issues to purchase equities in anticipation of a strong
U.S. economic recovery once the Iraqi conflict was resolved. By
mid-March, U.S. Treasury bond yields again rose to above 5%.
However, as there was growing sentiment that hostilities may not be
resolved in a matter of weeks, U.S. Treasury bond yields again
declined to end the month at 4.81%.

For the six months ended April 30, 2003, long-term U.S. Treasury
bond yields ratcheted back to near 5% by mid-April, as U.S. equity
markets continued to improve and the safe-haven premium U.S.
Treasury issues had commanded prior to the beginning of the Iraqi
conflict continued to be withdrawn. However, with the quick positive
resolution of the Iraqi war, investors quickly resumed their focus
on the fragile U.S. economic recovery. Business activity in the
United States has remained sluggish, especially job creation.
Investors have also been concerned that the recent SARS outbreak
would have a material, negative impact on world economic conditions,
especially in China and Japan. First quarter 2003 U.S. gross
domestic product was released in late April initially estimating
U.S. economic activity to be growing at 1.60%, well below many
analysts' assessments. These factors, as well as the possibility
that the Federal Reserve Board could again lower short-term interest
rates to encourage more robust U.S. economic growth, pushed bond
prices higher during the last two weeks of the period. By April 30,
2003, long-term U.S. Treasury bond yields had declined to almost
4.75%. Over the past six months, long-term U.S. bond yields fell
more than 20 basis points.

For the six months ended April 30, 2003, long-term tax-exempt bond
yields also fell modestly. Yield volatility was reduced relative to
that seen in U.S. Treasury issues, as municipal bond prices were
much less sensitive to worldwide geopolitical pressures on a daily
and weekly basis. Tax-exempt bond yields generally followed their
taxable counterparts higher, responding to a more positive U.S.
fixed income environment and continued slow economic growth. After
rising approximately 10 basis points in November 2002 to 5.30%,
municipal bond yields generally declined through February 2003. At
February 28, 2003, long-term tax-exempt revenue bond yields, as
measured by the Bond Buyer Revenue Bond Index, fell to approximately
5.05%. However, similar to U.S. Treasury bond yields, once military
action began in Iraq, municipal bond yields rose sharply to nearly
5.20% before declining to approximately 5.10% by the end of April.
Over the past six months, long-term tax-exempt bond yields fell
approximately 11 basis points, slightly less than U.S. Treasury
obligations.

A number of factors have combined to generate consistently strong
demand for municipal bonds throughout the six-month period ended
April 30, 2003. Generally weak U.S. equity markets have supported
continued positive demand for tax-exempt products as investors have
sought the relative security of fixed income issues. Also, with tax-
exempt money market rates near 1%, the demand for longer maturity
municipal issues has increased as investors have opted to buy longer
maturity issues rather than remain in cash reserves. Additionally,
investors received approximately $30 billion in January 2003 from
bond maturities, coupon income and proceeds from early redemptions.
However, these positive demand factors were not totally able to
offset the increase in tax-exempt new-issue supply, preventing more
significant declines in tax-exempt bond yields. This modest
underperformance has served to make municipal bonds a particularly
attractive purchase relative to their taxable counterparts.
Throughout most of the yield curve, municipal bonds have been able
to be purchased at yields near or exceeding those of comparable
Treasury issues. Compared to their recent historical averages of
82% - 88% of U.S. Treasury yields, municipal bond yield ratios in
their current 95% - 105% range are likely to prove attractive to
long-term investors.

Declining U.S. equity markets and escalating geopolitical pressures
have resulted in reduced economic activity and consumer confidence.
It is important to note that, despite all the recent negative
factors impeding the growth of U.S. businesses, the U.S. economy
still grew at an approximate 2.50% rate for all of 2002, twice that
of 2001. Similar expansion is expected for early 2003. Lower oil
prices, reduced geopolitical uncertainties, increased Federal
spending for defense, and a likely Federal tax cut are all factors
which should promote stronger economic growth later this year.
However, it is questionable to expect that business and investor
confidence can be so quickly restored as to trigger dramatic,
explosive U.S. economic growth and engender associated, large-scale
interest rate increases. The resumption of solid economic growth is
likely to be a gradual process accompanied by equally graduated
increases in bond yields. Moderate economic growth, especially
within a context of negligible inflationary pressures, should not
greatly endanger the positive fixed income environments tax-exempt
products currently enjoy.



MuniYield California Fund, Inc., April 30, 2003


Specific to California, the state's financial condition has
continued to deteriorate over the past six months. A weakened
national economy and its effect on the once powerful technology
sector led to a significant decline in income tax revenues,
resulting in a large state budget deficit. Prior to the state's
January budget revision, there was an approximate $35 billion budget
shortfall projected during the following 18-month period. One of the
efforts to close the gap was the issuance of tobacco revenue-backed
securities. California executed the largest single sale of municipal
bonds backed by revenues from the Master Settlement Agreement with
the four largest tobacco producers. California intended to come to
market with another transaction, effectively attempting to monetize
this future revenue stream, but a weakened demand for these
securities drove up borrowing costs. This second transaction, which
would total nearly $3 billion, has been postponed indefinitely. The
state has approached cutting spending, a more politically difficult
decision, and the proposed sale of nearly $3 billion of pension
bonds. The governor's office is also working with investment bankers
and caucus leaders as lawmakers consider up to $10 billion in
deficit financing to address the shortfall. However, details will
remain unclear until the state's May budget revision. The major
rating services currently have California general obligation debt
rated in the low single-A range.


Portfolio Strategy
The Fund employs leverage to attempt to provide a higher current
return of tax-exempt income to shareholders. Throughout the six
months ended April 30, 2003, we maintained a fully invested
position, with cash equivalent reserves averaging less than 2% of
total assets. Cash reserves were limited because of the tight
technical position of the California short-term marketplace. Yields
on California municipal cash equivalents were consistently averaged
near 1% throughout most of the period and are currently below 1% for
some tranches of the Fund's Preferred Stock. Our strategy was aimed
at creating a more defensive market structure within a leveraged
portfolio, which maintains both a fully invested posture and
contains a position of inverse floaters representing 14.5% of
assets. We have raised the Fund's overall average coupon levels and
shortened maturities through purchases in both the primary and
secondary California markets. The Fund's net asset value recently
exceeded $15.50, well above the original issue level of $15.00.
Going forward, our strategy is focused on protecting this price
level, since historically we have witnessed a reluctance of
municipal prices to move higher once the market has achieved these
levels. As market yields decline through 5%, retail investor demand
for California issues has historically declined. The market has
substantially exceeded these levels, and it is our aim to reduce
price volatility in the Fund from this point forward.

Steps taken to date include raising the average level of couponing
of the Fund's holdings and concentrating assets in parts of the
yield curve that we believe offer the best value for interest rate
risk taken. We have employed an interest rate swap representing 5%
of total assets to further seek to protect the Fund's asset
valuation. The use of leverage allowed the Fund to generate an above-
average yield. Consequently, it was not necessary to reach for
additional yield by compromising credit quality.

The action taken by the Federal Reserve Board in lowering interest
rates, combined with tight market technicals, resulted in a material
decrease in the Fund's borrowing cost. At April 30, 2003, the Fund
had three tranches of Preferred Stock. Two of these tranches were in
a seven-day floating rate mode; the third was fixed for a two-year
period (expiring October 2003). The decline in the short-term
interest rates has benefited the execution with respect to the two
floating rate tranches. This decline, in combination with a steep
tax-exempt yield curve, generated a material income benefit to the
Fund's Common Stock shareholder from the leveraging of the Preferred
Stock. These declines led to lower borrowing yields for the Fund and
increased yields for the Fund's Common Stock shareholder. However,
should the spread between short-term and long-term interest rates
narrow, the benefits of leverage will decline, and as a result,
reduce the yield on the Fund's Common Stock. (For a more complete
explanation of the benefits and risks of leveraging, see page 1 of
this report to shareholders.)

NOTES TO FINANCIAL STATEMENTS


1. Significant Accounting Policies:
MuniYield California Fund, Inc. (the "Fund") is registered under the
Investment Company Act of 1940 as a non-diversified, closed-end
management investment company. The Fund's financial statements are
prepared in conformity with accounting principles generally accepted
in the United States of America, which may require the use of
management accruals and estimates. These unaudited financial
statements reflect all adjustments, which are, in the opinion of
management, necessary to a fair statement of the results for the
interim period presented. All such adjustments are of a normal,
recurring nature. The Fund determines and makes available for
publication the net asset value of its Common Stock on a weekly
basis. The Fund's Common Stock is listed on the New York Stock
Exchange under the symbol MYC. The following is a summary of
significant accounting policies followed by the Fund.

(a) Valuation of investments--Municipal bonds are traded primarily
in the over-the-counter markets and are valued at the most recent
bid price or yield equivalent as obtained by the Fund's pricing
service from dealers that make markets in such securities. Financial
futures contracts and options thereon, which are traded on
exchanges, are valued at their closing prices as of the close of
such exchanges. Options written or purchased are valued at the last
sale price in the case of exchange-traded options. In the case of
options traded in the over-the-counter market, valuation is the last
asked price (options written) or the last bid price (options
purchased). Securities with remaining maturities of sixty days or
less are valued at amortized cost, which approximates market value.
Securities and assets for which market quotations are not readily
available are valued at fair value as determined in good faith by or
under the direction of the Board of Directors of the Fund, including
valuations furnished by a pricing service retained by the Fund,
which may utilize a matrix system for valuations. The procedures of
the pricing service and its valuations are reviewed by the officers
of the Fund under the general supervision of the Board of Directors.

(b) Derivative financial instruments--The Fund may engage in various
portfolio investment strategies both to increase the return of the
Fund and to hedge, or protect, its exposure to interest rate
movement and movements in the securities markets. Losses may arise
due to changes in the value of the contract or if the counterparty
does not perform under the contract.

* Financial futures contracts--The Fund may purchase or sell
financial futures contracts and options on such futures contracts.
Futures contracts are contracts for delayed delivery of securities
at a specific future date and at a specific price or yield. Upon
entering into a contract, the Fund deposits and maintains as
collateral such initial margin as required by the exchange on which
the transaction is effected. Pursuant to the contract, the Fund
agrees to receive from or pay to the broker an amount of cash equal
to the daily fluctuation in value of the contract. Such receipts or
payments are known as variation margin and are recorded by the Fund
as unrealized gains or losses. When the contract is closed, the Fund
records a realized gain or loss equal to the difference between the
value of the contract at the time it was opened and the value at the
time it was closed.

* Options--The Fund is authorized to write covered call options and
purchase put options. When the Fund writes an option, an amount
equal to the premium received by the Fund is reflected as an asset
and an equivalent liability. The amount of the liability is
subsequently marked to market to reflect the current market value of
the option written. When a security is purchased or sold through an
exercise of an option, the related premium paid (or received) is
added to (or deducted from) the basis of the security acquired or
deducted from (or added to) the proceeds of the security sold. When
an option expires (or the Fund enters into a closing transaction),
the Fund realizes a gain or loss on the option to the extent of the
premiums received or paid (or gain or loss to the extent the cost of
the closing transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.

* Forward interest rate swaps--The Fund is authorized to enter into
forward interest rate swaps. In a forward interest rate swap, the
Fund and the counterparty agree to pay or receive interest on a
specified notional contract amount, commencing on a specified future
effective date, unless terminated earlier. The value of the
agreement is determined by quoted fair values received daily by the
Fund from the counterparty. When the agreement is closed, the Fund
records a realized gain or loss in an amount equal to the value of
the agreement.

(c) Income taxes--It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated
investment companies and to distribute substantially all of its
taxable income to its shareholders. Therefore, no Federal income tax
provision is required.

(d) Security transactions and investment income--Security
transactions are recorded on the dates the transactions are entered
into (the trade dates). Realized gains and losses on security
transactions are determined on the identified cost basis. Dividend
income is recorded on the ex-dividend dates. Interest income is
recognized on the accrual basis. The Fund amortizes all premiums and
discounts on debt securities.

(e) Dividends and distributions--Dividends from net investment
income are declared and paid monthly. Distributions of capital gains
are recorded on the ex-dividend dates.


2. Investment Advisory Agreement and Transactions with Affiliates:
The Fund has entered into an Investment Advisory Agreement with Fund

Total                               $    132,333       $ 34,933,322
                                    ============       ============

tax purposes aggregated $35,012,620, of which $35,816,068 related
to appreciated securities and $803,448 related to depreciated

4. Stock Transactions:
The Fund is authorized to issue 200,000,000 shares of stock,
including Preferred Stock, par value $.10 per share, all of which
were initially classified as Common Stock. The Board of Directors is

without approval of the holders of Common Stock.

Common Stock
Shares issued and outstanding during the six months ended April 30,
2003 remained constant and during the year ended October 31, 2002
increased by 110,780 as a result of dividend reinvestment.

Preferred Stock
Auction Market Preferred Stock ("AMPS") are shares of Preferred
Stock of the Fund, with a par value of $.10 per share and a
liquidation preference of $25,000 per share, that entitle their
holders to receive cash dividends at an annual rate that may vary
for the successive dividend periods. The yields in effect at April
30, 2003 were: Series A, 3.14%; Series B, 1.15% and Series C, .95%.

Shares issued and outstanding during the six months ended April 30,
2003 and during the year ended October 31, 2002 remained constant.

MuniYield California Fund, Inc., April 30, 2003


MANAGED DIVIDEND POLICY


The Fund's dividend policy is to distribute all or a portion of its
net investment income to its shareholders on a monthly basis. In
order to provide shareholders with a more consistent yield to the
current trading price of shares of Common Stock of the Fund, the
Fund may at times pay out less than the entire amount of net
investment income earned in any particular month and may at times in
any month pay out such accumulated but undistributed income in
addition to net investment income earned in that month. As a result,
the dividends paid by the Fund for any particular month may be more
or less than the amount of net investment income earned by the Fund
during such month. The Fund's current accumulated but undistributed
net investment income, if any, is disclosed in the Statement of Net
Assets, which comprises part of the Financial Information included
in this report.
