LETTER TO THE SHAREHOLDERS March 31, 1998 

DEAR SHAREHOLDER: 

We are pleased to present the annual report on the operations of Dean Witter 
Limited Term Municipal Trust for the fiscal year ended March 31, 1998. 

Since our interim report six months ago, the securities markets have been 
influenced by the Asian financial crisis and its potential impact on the U.S. 
economy. Foreign currency turmoil strengthened the value of the U.S. dollar 
and created a "flight to quality" demand for U.S. Treasury securities. 
Municipal bonds followed the trend of Treasuries, with yields declining to a 
range last seen 20 years ago. Domestic employment conditions strengthened as 
unemployment fell to its lowest level since 1973. The bond market rally was 
also aided by prospects of the first federal budget surplus in more than two 
decades. Inflation remained subdued despite the economy's strength. 

MUNICIPAL MARKET CONDITIONS 

Intermediate-term municipal bond yields, as measured by 10-year double 
"A"-rated general obligation bonds, declined 30 basis points from 4.85 
percent in August 1997 to 4.55 percent at the end of March 1998. As usually 
happens when yields change, the municipal rally lagged the rally in 
Treasuries. The ratio of 10-year double "A"-rated general obligation bond 
yields to 10-year U.S. Treasury yields improved from a relatively rich 76 
percent in August to a more attractive 81 percent in March. A rising ratio 
means that municipals have underperformed Treasuries and have become 
relatively more attractive.

PERFORMANCE 

Dean Witter Limited Term Municipal Trust's total return for the fiscal year 
ended March 31, 1998, was 7.70 percent. Tax-free dividends totaling $0.40 per 
share were paid during the period. The Fund's net asset value increased from 
$9.91 to $10.26 per share. 

The accompanying chart illustrates the performance of a hypothetical $10,000 
investment in the Fund since inception (July 12, 1993) versus the performance 
of the Lehman Brothers 10-Year Municipal Bond Index and the Lipper Analytical 
Services, Inc. Intermediate Municipal Debt Funds Index. 

PORTFOLIO STRUCTURE 
As of March 31, 1998, intermediate-term municipal bonds represented 88 
percent of the Fund's net assets. The Fund's short-term investment position

The portfolio was diversified among 13 specific municipal sectors and 36 
separate issuers. The portfolio's average maturity was 5.3 years and its 
duration was 4.9 years. Bonds subject to the alternative minimum tax (AMT) 
accounted for 18 percent of net assets. The portfolio maintained high quality 
with more than half of the bonds rated double or triple "A", as measured by 
Standard & Poor's Corp. or Moody's Investors Service, Inc. At the end of 
March, the Fund's net assets were in excess of $57 million.

LOOKING AHEAD 

The economic fundamentals are in place for another year of solid, albeit less 
spectacular, domestic growth in 1998. Events in the Far East have 
strengthened the U.S. dollar and led to lower interest rates. The Asian 
financial crisis seems likely to moderate U.S. economic growth and 
inflationary pressures. While this outlook is favorable for municipal bonds, 
it is possible that the Federal Reserve Board may tighten monetary policy if 
cost pressures mount. 

We appreciate your ongoing support of Dean Witter Limited Term Municipal 
Trust and look forward to continuing to serve your investment needs. 

Very truly yours, 

/s/ Charles A. Fiumefreddo

1. ORGANIZATION AND ACCOUNTING POLICIES 

Dean Witter Limited Term Municipal Trust (the "Fund") is registered under the 
Investment Company Act of 1940, as amended, as a diversified, open-end 
management investment company. The Fund's investment objective is to provide 
a high level of current income which is exempt from federal income tax, 
consistent with the preservation of capital and prescribed standards of 
quality and maturity. The Fund seeks to achieve this objective by investing 
primarily in intermediate term, investment grade municipal securities. The 
Fund was organized as a Massachusetts business trust on February 25, 1993 and 
commenced operations on July 12, 1993. 

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 by an outside 
independent pricing service approved by the Trustees. The pricing service has 
informed the Fund 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. Discounts are accreted and premiums are amortized over the life of 
the respective securities. Interest income is accrued daily. 

C. FEDERAL INCOME TAX STATUS--It is the Fund'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.

NOTES TO FINANCIAL STATEMENTS March 31, 1998, continued 

D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS--The Fund records dividends 
and distributions to its shareholders on the record 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--Dean Witter InterCapital Inc. (the "Investment 
Manager") paid the organizational expenses of the Fund in the amount of 
$141,529 which were reimbursed exclusive of $12,651 which was absorbed by the 
Investment Manager. 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 Fund pays the Investment 
Manager a management fee, accrued daily and payable monthly, by applying the 
annual rate of 0.50% to the Fund's net assets determined as of the close of 
each business day. 

Under the terms of the Agreement, in addition to managing the Fund's 
investments, the Investment Manager maintains certain of the Fund'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 Fund 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 
Fund. 

3. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES 

The proceeds from sales of portfolio securities, excluding short-term 
investments, for the year ended March 31, 1998 aggregated $5,532,680.

Morgan Stanley Dean Witter Trust FSB, an affiliate of the Investment Manager, 
is the Fund's transfer agent. At March 31, 1998, the Fund had transfer agent

The Fund has an unfunded noncontributory defined benefit pension plan 
covering all independent Trustees of the Fund who will have served as 
independent Trustees for at least five years at the time of retirement. 
Benefits under this plan are based on years of service and compensation 
during the last five years of service. Aggregate pension costs for the year 
ended March 31, 1998 included in Trustees' fees and expenses in the Statement 
of Operations amounted to $5,871. At March 31, 1998, the Fund had an accrued 
pension liability of $25,014 which is included in accrued expenses in the

REPORT OF INDEPENDENT ACCOUNTANTS 

TO THE SHAREHOLDERS AND TRUSTEES 
OF DEAN WITTER LIMITED TERM MUNICIPAL TRUST 

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 Dean Witter 
Limited Term Municipal Trust (the "Fund") at March 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 July 
12, 1993 (commencement of operations) through March 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 Fund'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 March 
31, 1998 by correspondence with the custodian, provide a reasonable basis for 
the opinion expressed above.
