LETTER TO THE SHAREHOLDERS October 31, 1998             New York, New York 10048
 
DEAR SHAREHOLDER:
 
We are pleased to present the annual report on the operations of Morgan Stanley
Dean Witter Insured California Municipal Securities (ICS) for the fiscal year
ended October 31, 1998.
 
On December 21, 1998, after the close of the period under review, the Trust
changed its name from InterCapital Insured California Municipal Securities to
Morgan Stanley Dean Witter Insured California Municipal Securities. Information
on the name change was mailed to shareholders in mid-December under separate
cover.
 
Since our last report six months ago, global financial turmoil, including the
Russian currency crisis, has continued to affect the securities markets. This
led to a flight-to-quality rally for U.S. Treasury bonds, with yields falling to
30-year lows. Municipal bond yields declined but lagged the downward trend of
Treasury yields.
 
The deflationary impact of the international financial crisis began to temper
U.S. economic growth prior to the summer's tumultuous market activity. Lower
commodity prices, cheaper imports and improved

LETTER TO THE SHAREHOLDERS October 31, 1998, continued
 
productivity offset the potential inflationary impact of strong domestic
employment. With inflation held in check, the Federal Reserve Board provided
liquidity to the markets by lowering short-term interest rates. Since the end of
September, the Federal Reserve Open Market Committee cut the federal funds rate
75 basis points from 5.50 percent to 4.75 percent in three separate moves.
 
MUNICIPAL MARKET CONDITIONS
 
Municipal bond yields followed the downward trend of Treasury yields at a more
moderate pace. At the end of October, long-term insured municipal index yields
stood at 5.05 percent, index yields declined 30 basis points over the last 12
months. In contrast, 30-year U.S. Treasury bond yields fell 100 basis points
during the same period.
 
As municipals lagged the rally in Treasuries, the ratio of municipal yields to
Treasury yields rose sharply to 98 percent. (A rising ratio means that
municipals have underperformed Treasuries and have become more attractive on a
relative basis.) This increase was similar to the jump witnessed in 1986, when
tax-reform proposals threatened the favorable tax advantage of municipal bonds.
 
The overall decline in interest rates has led to a substantial increase in new
issue municipal volume. Municipal issuance is on a pace to challenge 1993's
underwriting record of $292 billion. Year-to-date, total municipal volume of
$234 billion is up 32 percent. Half the underwriting volume was enhanced with
bond insurance. Refundings represented 30 percent of total new issuance.
California new issue underwriting accounted for 12 percent of national volume.
 
PERFORMANCE
 
The Trust's net asset value (NAV) increased from $15.50 to $16.00 per share
during the fiscal year ended October 31, 1998. Based on this NAV change plus
reinvestment of tax-free dividends of $0.7775 per share, the Trust's total NAV
return was 8.69 percent. ICS's price on the New York Stock Exchange moved from
$14.375 to $15.25 per share. Based on this change in market price plus
reinvestment of dividends, the Trust's total market return was 11.71 percent. On
October 31, 1998, the Trust traded at a 4.69 percent discount to NAV.
 
Monthly dividends for the fourth quarter of 1998 were declared in September.
Beginning with the October 1998 dividend, the monthly dividend was reduced from
$0.065 per share to $0.0625 per share, to more closely reflect the Trust's
anticipated income. The level of undistributed net investment income declined
from $0.086 to $0.072 per share. Subsequent to the end of the fiscal year, the
Trust declared a capital gain distribution of $0.1566 per share.

PORTFOLIO STRUCTURE
 
The Trust remained fully invested in long-term municipal bonds during the fiscal
year. Investments were diversified among 12 long-term sectors and 27 credits. As
illustrated in the accompanying chart, the distribution of call dates in the
portfolio produced 6 years of weighted average call protection.
 
The Trust's weighted average maturity was 21 years. Average duration (a measure
of price volatility to interest rate changes) was 7 years. To assure the timely
payment of principal and interest, each position in the portfolio was backed by
triple "A" rated bond insurance.
 
LOOKING AHEAD
 
Global economic conditions seem likely to keep inflationary pressures under
control and have contributed to lower interest rates. The fixed-income markets
have also begun to anticipate the possibility of additional monetary easing by
the Fed. With the municipal relationship to Treasuries more favorable than it
has been in the last 10 years, the outlook for municipal bonds is positive.
 
The Trust's procedure for reinvestment of all dividends and distributions on
common shares is through purchases in the open market. This method helps to
support the market value of the Trust's shares. In addition, we would like to
remind you that the Trustees have approved a procedure whereby the Trust may,
when appropriate, purchase shares in the open market or in privately negotiated
transactions at a price not above market value or net asset value, whichever is
lower at the time of purchase.
 
We appreciate your ongoing support of Morgan Stanley Dean Witter Insured
California Municipal Securities and look forward to continuing to serve your
investment needs.
 
Very truly yours,
 
/S/ CHARLES A. FIUMEFREDDO

MORGAN STANLEY DEAN WITTER INSURED CALIFORNIA MUNICIPAL SECURITIES
 
NOTES TO FINANCIAL STATEMENTS October 31, 1998
 
1. ORGANIZATION AND ACCOUNTING POLICIES
 
Morgan Stanley Dean Witter Insured California Municipal Securities (the
"Trust"), formerly InterCapital Insured California Municipal Securities (the
Trust changed its name effective December 21, 1998), is registered under the
Investment Company Act of 1940, as amended, as a diversified, closed-end
management investment company. The Trust's investment objective is to provide
current income which is exempt from both federal and California income taxes.
The Trust was organized as a Massachusetts business trust on October 14, 1993
and commenced operations on February 28, 1994.
 
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures. Actual results could differ from
those estimates.
 
The following is a summary of significant accounting policies:
 
A. VALUATION OF INVESTMENTS -- Portfolio securities are valued for the Trust by
an outside independent pricing service approved by the Trustees. The pricing
service has informed the Trust that in valuing the portfolio securities, it uses
both a computerized matrix of tax-exempt securities and evaluations by its
staff, in each case based on information concerning market transactions and
quotations from dealers which reflect the bid side of the market each day. The
portfolio securities are thus valued by reference to a combination of
transactions and quotations for the same or other securities believed to be
comparable in quality, coupon, maturity, type of issue, call provisions, trading
characteristics and other features deemed to be relevant. Short-term debt
securities having a maturity date of more than sixty days at time of purchase
are valued on a mark-to-market basis until sixty days prior to maturity and
thereafter at amortized cost based on their value on the 61st day. Short-term
debt securities having a maturity date of sixty days or less at the time of
purchase are valued at amortized cost.
 
B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
The Trust amortizes premiums and accretes discounts over the life of the
respective securities. Interest income is accrued daily.
 
C. FEDERAL INCOME TAX STATUS -- It is the Trust's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its taxable and nontaxable income to its
shareholders. Accordingly, no federal income tax provision is required.

MORGAN STANLEY DEAN WITTER INSURED CALIFORNIA MUNICIPAL SECURITIES
 
NOTES TO FINANCIAL STATEMENTS October 31, 1998, continued
 
D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Trust records dividends
and distributions to its shareholders on the ex-dividend date. The amount of
dividends and distributions from net investment income and net realized capital
gains are determined in accordance with federal income tax regulations which may
differ from generally accepted accounting principles. These "book/tax"
differences are either considered temporary or permanent in nature. To the
extent these differences are permanent in nature, such amounts are reclassified
within the capital accounts based on their federal tax-basis treatment;
temporary differences do not require reclassification. Dividends and
distributions which exceed net investment income and net realized capital gains
for financial reporting purposes but not for tax purposes are reported as
dividends in excess of net investment income or distributions in excess of net
realized capital gains. To the extent they exceed net investment income and net
realized capital gains for tax purposes, they are reported as distributions of
paid-in-capital.
 
E. ORGANIZATIONAL EXPENSES -- Morgan Stanley Dean Witter Advisors Inc. (the
"Investment Manager"), formerly Dean Witter InterCapital Inc. paid the
organizational expenses of the Trust's common shares in the amount of $40,000
which have been reimbursed by the Trust for the full amount thereof. Such
expenses have been deferred and are being amortized by the straight-line method
over a period not to exceed five years from the commencement of operations.
 
2. INVESTMENT MANAGEMENT AGREEMENT
 
Pursuant to an Investment Management Agreement, the Trust pays the Investment
Manager a management fee, calculated weekly and payable monthly, by applying the
annual rate of 0.35% to the Trust's weekly net assets.
 
Under the terms of the Agreement, in addition to managing the Trust's
investments, the Investment Manager maintains certain of the Trust's books and
records and furnishes, at its own expense, office space, facilities, equipment,
clerical, bookkeeping and certain legal services and pays the salaries of all
personnel, including officers of the Trust who are employees of the Investment
Manager. The Investment Manager also bears the cost of telephone services, heat,
light, power and other utilities provided to the Trust.
 
3. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES
 
The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the year ended October 31, 1998 aggregated
$10,354,399 and $7,508,469, respectively.

NOTES TO FINANCIAL STATEMENTS October 31, 1998, continued
 
Morgan Stanley Dean Witter Trust FSB, an affiliate of the Investment Manager, is
the Trust's transfer agent. At October 31, 1998, the Trust had transfer agent
fees and expenses payable of approximately $400.
 
4. PREFERRED SHARES OF BENEFICIAL INTEREST
 
The Trust is authorized to issue up to 1,000,000 non-participating preferred
shares of beneficial interest having a par value of $.01 per share, in one or
more series, with rights as determined by the Trustees, without approval of the
common shareholders. The preferred shares have a liquidation value of $50,000
per share plus the redemption premium, if any, plus accumulated but unpaid
dividends, whether or not declared, thereon to the date of distribution. The
Trust may redeem such shares, in whole or in part, at the original purchase
price of $50,000 per share plus accumulated but unpaid dividends, whether or not
declared, thereon to the date of redemption.
 
Upon issuance, the Trust will be subject to certain restrictions relating to the
preferred shares. Failure to comply with these restrictions could preclude the
Trust from declaring any distributions to common shareholders or purchasing
common shares and/or could trigger the mandatory redemption of preferred shares
at liquidation value.
 
The preferred shares, entitled to one vote per share, generally vote with the
common shares but vote separately as a class to elect two Trustees and on any
matters affecting the rights of the preferred shares.
 
5. COMMON SHARES OF BENEFICIAL INTEREST
 
Transactions in common shares of beneficial interest were as follows:

MORGAN STANLEY DEAN WITTER INSURED CALIFORNIA MUNICIPAL SECURITIES
 
REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE SHAREHOLDERS AND TRUSTEES
OF MORGAN STANLEY DEAN WITTER INSURED CALIFORNIA MUNICIPAL SECURITIES
 
In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Morgan Stanley Dean Witter Insured
California Municipal Securities (the " Trust"), formerly InterCapital Insured
California Municipal Securities, at October 31, 1998, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended and the financial highlights for each of
the four years in the period then ended and for the period February 28, 1994
(commencement of operations) through October 31, 1994, in conformity with
generally accepted accounting principles. These financial statements and
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Trust's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at October 31, 1998 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above.
