"WE BELIEVE RISING

TREASURY PRICES LEFT

MUNICIPAL BONDS IN

A POSITION OF

RELATIVE VALUE."



Dear Shareholder


October 9, 2000

Recap of Events - Throughout most of the Funds' fiscal year ended August 31,
2000, the Federal Reserve Board focused on tightening the U.S. money supply,
conducting a prolonged series of interest rate hikes. A strong U.S. economy and
threatening inflation prompted the Fed to bump up short-term interest rates four
times during the period, with the last increase coming on May 16, 2000.

During the fall of 1999, many bond buyers seemed to be ignoring municipal bonds
in favor of the higher-yielding corporate bonds that were flooding the market.
That scenario changed later in our fiscal year when interest rate hikes in
February and March, coupled with the U.S. Treasury buyback and turmoil in the
U.S. stock market in April, led to a marked increase in demand for the safety of
U.S. Treasury securities. We believe rising Treasury prices left municipal bonds
in a position of relative value. Investors began to recognize this value as
Treasury yields dropped and AAA-rated municipal bond yields exceeded 6% in March
(Source: Bloomberg). Since then, we have generally seen demand for municipal
bonds on the upswing.*

Increased tax revenue resulting from the strong economy and higher borrowing
costs resulting from rising interest rates caused many state and local
governments to reduce the number of municipal bonds they issued during our
fiscal year. This caused demand to exceed supply as we ended our year (Source:
Moody's Investors Service Inc.).

"WE ARE ENCOURAGED BY

THE CURRENT MARKET

ENVIRONMENT."



The flip-flop between supply and demand in the municipal markets happened
gradually throughout 2000. The Fed's latest interest rate hike in May supported
that trend. By the end of our fiscal year, demand for municipal bonds remained
high while municipal bond issuance for 2000 declined by about 19%, a reduction
of about $33 billion from the same period one year prior (Source: Thomson
Financial).

Long-term interest rates began to decline during the summer months, with the
30-year mortgage rate at 7.64% on August 31, 2000, about three quarters of a
percentage point off its spring 2000 high for the year. The average yield on
30-year AAA-rated municipal bonds, which rarely is more than the yield for the
30-year Treasury bond, stood at 5.68% on August 31, 2000. By comparison, the
30-year Treasury bond was yielding 5.66% and two-year Treasury notes 6.16% on
August 31, 2000 (Source: Bloomberg).* For municipal bond tax-equivalent yields,
see the chart on page 8.

Delaware's Municipal Bond Funds for Idaho, Iowa, Kansas, Missouri, Montana,
North Dakota, Oregon, and Wisconsin struggled during the first half of the
fiscal year, but then rode the municipal market rally to solid overall returns
as of August 31, 2000.

The Funds' portfolios are managed with a long-term perspective. Therefore,
relatively few significant changes were made to the Funds during the fiscal
year. This long-term investment approach can minimize trading costs and limit
capital gains. As a result, investors may get to keep more of what they earn.
While there was a relatively small supply of bonds in some states, the scant
supply of new bonds often helped improve the value of the bonds we held.

 bonds, unlike Treasuries.

Market Outlook - We are encouraged by the current market environment. As of this
writing, the predominant opinion on Wall Street is that the Fed is firmly in a
holding pattern with regard to its actions on interest rates. Evident slowing in
the U.S. economy, which has prompted the Fed to leave rates untouched at its
last three meetings, could eventually lead to lesser revenues for states and
municipalities. In our opinion, this would likely lead to a general increase in
the issuance of municipal bonds.

We believe that municipal bonds will continue to play a role in well-diversified
portfolios. In addition, we believe that in an environment where interest rates
trend downward, investing in municipal bond funds could prove to be more
attractive to investors than buying individual bonds. In such an environment,
municipal bond funds, like Delaware's, are holding slightly older bonds -- many
of which were issued at more attractive rates than most new issues coming to
market.

Thank you for your continued confidence and your commitment to Delaware
Investments.

Sincerely,



/s/Wayne A. Stork                         /s/David K. Downes

PORTFOLIO MANAGEMENT REVIEW
---------------------------

The Funds' Results
During the year ended August 31, 2000, we began to see strong performance in
municipal markets despite changing interest rates. While municipal bond fund
cash flows are negative year-to-date, July 2000 brought positive numbers that we
hope to see continue, with investors pouring a net $850 million dollars into
municipal bond funds (Source: Investment Company Institute).

The year was characterized by a continued diminishing of municipal bond supply,
as states, counties, and municipalities issued fewer bonds, likely due to strong
local economies and tax bases, as well as the dramatic decline in bond
refunding. Although healthcare bonds were weak during the period, bond issues
for public projects such as transportation and higher education often exhibited
strength. Credit upgrades for bonds were also substantial -- especially among
tax-backed bonds (Source: Moody's Investors Service).

State and local municipalities in the Midwest and Pacific Northwest continued to
enjoy fiscal prosperity during the year. We believe the credit quality of most
states in these two regions is relatively high, and we anticipate that the
credit ratings of the bonds we hold will generally remain solid. During July and
August, widespread forest fires affected many Northwestern states. Although the
clean-up and rebuilding that takes place afterwards will be costly, we think
that fire-related expenses will ultimately not affect local economies in a
profound way. These states had strong bases prior to the fires, and are likely
to receive a significant amount of federal aid afterward.

The fluctuating interest rate environment, meanwhile, dictated the need
throughout our fiscal year for managing portfolio duration -- a key statistic
that indicates a bond fund's sensitivity to interest rate movement.

Delaware Tax-Free Idaho Fund

Delaware Tax-Free Idaho Fund had a total return of +3.25% (for Class A shares at
net asset value with distributions reinvested) for the year ended August 31,
2000. The Fund did not perform as well as other funds in its peer group, the
Lipper Other States Municipal Debt Funds, which returned +4.54% for the same
period. We held a modest percentage of the Fund's assets in Industrial
Development Revenue bonds (IDRs). The Fund's performance was mildly hampered at
times by these holdings as prices for IDRs declined during the period, which
occurred in response to weakness in the corporate bond market in relation to
U.S. Treasuries. We continue to hold IDRs as we believe this is a temporary
situation.

While issuance of double tax-exempt bonds was generally sparse during the
period, we found supply to be adequate. The Fund was fully invested during the
period, and more than 20% of the bonds in the portfolio were non-rated.
Non-rated bonds are typically issued by small municipalities looking to avoid
the expense of obtaining a credit rating from a major agency like Moody's or
Standard & Poor's. We rigorously research non-rated bond issues before adding
them to the portfolio, and once the bonds are part of our portfolio we monitor
their credit quality on a regular basis.

We maintained duration in the mid-range, which is in line with our peers. We
generally held bonds with higher credit ratings than our peers, which helped the
Fund's performance.

Idaho was one of the states affected by forest fires during the summer. The
fires generated an increase in unemployment benefit payouts, and also affected
the state's tourism and recreation industry. Idaho ended fiscal 1999 with an
operating surplus, and its general fund revenues grew by 9.6%, which was larger
than expected (Source: Standard & Poor's). We believe that the cost of the fires
will have a relatively small effect on Idaho's overall economy. Because the
economic and financial condition of the state has improved in recent years, our
general outlook for Idaho is favorable.

Delaware Tax-Free Iowa Fund
Delaware Tax-Free Iowa Fund had a total return of +5.35% (for Class A shares at
net asset value with distributions reinvested) for the year ended August 31,
2000. We succeeded in preserving capital to a greater degree than the Fund's
peer group, which delivered a 4.54% return for the same period. The Fund seeks
to invest exclusively in bonds that are exempt from both federal and state
income tax. During the fiscal year, there were relatively few new issues of
double tax-exempt bonds in Iowa. Nevertheless, the Fund was fully invested.
During the year, we kept the Fund's duration at a point that we considered to be
modestly long. This approach benefited the Fund when long interest rates began
to decline in May 2000.

In addition, the Fund benefited from strong credit selection in a state that is
currently enjoying a sound economy. While Iowa continues to be largely dependent
on agriculture, its broad economy has become more diversified in recent years,
and the state has reaped the rewards of that diversity. Revenues generated by
the services and finances sectors, as well as the insurance and real estate
sectors, have contributed to Iowa's general fund balance. In the past fiscal
year, the state has also benefited from increased revenues derived from
legalized gambling.

Delaware Tax-Free Kansas Fund
Delaware Tax-Free Kansas Fund had a total return of +4.14% (for Class A shares
at net asset value with distributions reinvested) for the year ended August 31,
2000. The Fund's performance fell slightly below that of its peers, as measured
by the Lipper Kansas Municipal Debt Funds Average, which returned +4.44% for the
same period.

More than 30% of the portfolio was invested in BBB and non-rated bonds, and
these lower-rated investment grade issues helped increase the Fund's dividend,
but didn't rally as strong as AA and AAA high-grade bonds over the time period.
Kansas continues to benefit from a broad and diverse economy that continues to
provide growth in income and employment. Growth in services, trade, construction
and manufacturing has increased economic diversity in the state and has lessened
the state's dependence on the more cyclical agricultural sector.

Delaware Tax-Free Missouri Insured Fund
Delaware Tax-Free Missouri Insured Fund had a total return of +4.99% (for Class
A shares at net asset value with distributions reinvested) for the year ended
August 31, 2000, outperforming other funds in its peer group, as measured by the
Lipper Missouri Municipal Debt Funds Average, which posted a +4.91% return for
the same period.

The Fund was invested exclusively in insured bonds rated AAA by Standard &
Poor's -- the highest credit rating available. About 27% of the Fund's holdings
were in pre-refunded bonds. Issuers often pre-refund their outstanding bonds
when interest rates decline in order to reduce their interest costs. As the year
progressed and long-term interest rates declined, some bonds in the portfolio
were pre-refunded. In most cases, we continue to hold bonds once they have been
pre-refunded. Pre-refunded bonds often help a Fund because:

[ ]  Pre-refunded bonds are backed by investments in U.S. government bonds,
     which are held in a separate escrow account.

[ ]  The price and credit quality increases because the bond will be paid off at
     the first call date.

[ ]  In general, prices for these bonds are less sensitive to interest rate
     fluctuations.

Rapid growth in many Missouri cities has led to increased housing and commercial
real estate development. Such growth has boosted property values and tax
revenues. We believe Missouri's municipalities should continue to benefit from
this positive development. In addition, with the recovery of the Asian markets,
the state's exports have rebounded from a slump over the past two years.

Delaware Montana Municipal Bond Fund
Delaware Montana Municipal Bond Fund had a total return of +6.10% (for Class A
shares at net asset value with distributions reinvested) since the Fund's
inception on November 2, 1999 through August 31, 2000. The Fund slightly
underperformed the average of its peers in the Lipper Other States Municipal
Debt Funds Average, which returned +6.38% for the same period. During the fiscal
year, the supply of bonds exempt from both federal and state income tax was very
sparse, but adequate for our needs, and the Fund was fully invested in
investment-grade issues.

It is estimated that the Montana wildfires will cost the state approximately $60
million in fire-related expenses, unemployment compensation and small business
loans (Source: Standard & Poor's). While the state expects to receive
considerable federal assistance with fire-related costs, a significant
contribution from the state's general fund will likely be necessary. Current
estimates indicate that the state will have to spend approximately $12 million,
or about 9.2% of its fiscal year-end 1999 general fund balance for fire-related
expenses. However, recent reports estimate that Montana's general fund balance
for fiscal year-end 2000 is encouraging, even surpassing earlier projections
(Source: Standard & Poor's). So far, the state has been able to absorb the fire
fighting expenses, and the fires have had no immediate effect on Montana's
credit rating, according to Standard & Poor's. Because the economic and
financial condition of the state has improved in recent years, our general
outlook for Montana is favorable.

Delaware Tax-Free North Dakota Fund
Delaware Tax-Free North Dakota Fund had a total return of +3.58% (for Class A
shares at net asset value with distributions reinvested) for the year ended
August 31, 2000. The Fund's return lagged that of the average fund in its peer
group, as measured by the Lipper Other States Municipal Debt Funds Average,
which returned +4.54% for the same period.

Despite its reliance on agriculture and oil production, North Dakota's economic
base has remained stable. With access to Canadian markets, North Dakota is a
regional distribution hub for surrounding states. Financial services growth has
benefited from the state's proximity to Minnesota, as Minnesota-based financial
services companies have frequently been relocating back-office operations to the
low tax environment of North Dakota.

Delaware Tax-Free Oregon Insured Fund
Delaware Tax-Free Oregon Insured Fund had a total return of +6.04% (for Class A
shares at net asset value with distributions reinvested) for the year ended
August 31, 2000. The Fund outperformed its peers in the Lipper Oregon Municipal
Debt Fund Average, which returned +5.20% for the same period.

The Fund was invested exclusively in insured bonds rated AAA by Standard &
Poor's. Much of the Fund's relatively strong performance can be attributed to
discount bonds that were purchased several years ago. As long-term interest
rates declined, prices on these bonds often rose significantly.

In recent years, Oregon has benefited from a growing economy, an expanding
population and a growing labor force. The state has moved away from its heavy
reliance on timber and agriculture, and now enjoys a broader mix of high
technology, service and international trade businesses. The state's current
economic forecast suggests that its economy may grow at a slightly greater rate
than that of the national economy in fiscal 2000 and 2001(Source: Standard &
Poor's).

Delaware Tax-Free Wisconsin Fund
Delaware Tax-Free Wisconsin Fund had a total return of +4.62% (for Class A
shares at net asset value with distributions reinvested) for the year ended
August 31, 2000. The Fund outperformed the average fund in its peer group, the
Lipper Other States Municipal Debt Funds Average, which posted +4.54% for the
same period. The Fund was fully invested in high-quality issues, which
contributed to the Fund's strong return.

While there are many municipal issuers in the state, relatively few issue double
tax-exempt bonds. Because supply was low during the period, we continued to
supplement the Fund's investments with double tax-exempt bonds issued by Puerto
Rico and the Virgin Islands. A trend of strong economic and employment growth
continued to benefit Wisconsin during the period. Wisconsin ranks second in the
nation, behind Michigan, in manufacturing jobs. However, most of Wisconsin's
employment growth has been in the service and trade sectors of the economy. Over
the next few years, economic growth is expected to be positive but is not
expected to outpace that of the nation (Source: Standard & Poor's).

Outlook
In the months ahead, we anticipate a positive environment for municipal bonds.
We think it is possible that the strong performance seen in the first half of
2000 could continue through the fall.

As always with municipal bonds, this depends largely on interest rate trends, as
well as supply and demand in the municipal markets. As of this writing,
long-term interest rates have been trending downward. And while the Federal
Reserve Board has promised to remain vigilant about keeping inflation under
control, many analysts and investors seem to agree that short-term rate
increases may be finished for this year.

We feel that a non-inflationary U.S. economy that has less-robust growth is
likely to boost the demand for capital funding. This would be a positive for
municipal bonds and for the Funds. In our opinion, municipal bond funds will
continue to be an important investment vehicle -- which can provide
diversification to an investor's overall portfolio, as well as providing
individual investors with a vehicle that strives to preserve capital and
generate non-taxable income.*

Returns reflect reinvestment of distributions and any applicable sales charges
as noted below. Return and share values will fluctuate so that shares, when
redeemed, may be worth more or less than their original cost. Class B and C
share results, excluding sales charges, assume either that contingent deferred
sales charges did not apply or the investment was not redeemed. Past performance
is not a guarantee of future results.

Class A shares have a 3.75% maximum front-end sales charge and a 12b-1 fee.

Class B shares do not have a front-end sales charge, but are subject to a 1%
annual distribution and service fee. They are also subject to a contingent
deferred sales charge of up to 4% if redeemed before the end of the sixth year.

Class C shares have a 1% annual distribution and service fee. If redeemed within
12 months, a 1% contingent deferred sales charge applies.

An expense limitation was in effect for all classes of Delaware Tax-Free Idaho
Fund during the periods shown. Performance would have been lower if the expense
limitation was not in effect.

Chart assumes $10,000 invested on September 1, 1993 and includes the effect of a
3.75% front-end sales charge and the reinvestment of all dividends and capital
gains. Performance of other Fund classes will vary due to differing charges and
expenses. Returns plotted on the chart were as of the last day of each
successive month. Past performance does not guarantee future results.

Returns reflect reinvestment of distributions and any applicable sales charges
as noted below. Return and share values will fluctuate so that shares, when
redeemed, may be worth more or less than their original cost. Class B and C
share results, excluding sales charges, assume either that contingent deferred
sales charges did not apply or the investment was not redeemed. Past performance
is not a guarantee of future results.

Class A shares have a 3.75% maximum front-end sales charge and a 12b-1 fee.

Class B shares do not have a front-end sales charge, but are subject to a 1%
annual distribution and service fee. They are also subject to a contingent
deferred sales charge of up to 4% if redeemed before the end of the sixth year.

Class C shares have a 1% annual distribution and service fee. If redeemed within
12 months, a 1% contingent deferred sales charge applies.

An expense limitation was in effect for all classes of Delaware Tax-Free
Wisconsin Fund during the periods shown. Performance would have been lower if
the expense limitation was not in effect.

the Investment Company Act of 1940, as amended. The Funds offer three classes of
shares. The A Class carries a maximum front-end sales charge of 3.75%. The B

load deferred sales charge.

The Delaware Tax-Free Idaho Fund, Delaware Tax-Free Iowa Fund, Delaware Montana
Municipal Bond Fund, Delaware Tax-Free North Dakota Fund, and Delaware Tax-Free
Wisconsin Fund seek high current income free from both federal and state income
taxes by investing in investment grade municipal bonds. The Delaware Tax-Free
Missouri Insured Fund and Delaware Tax-Free Oregon Insured Fund seek high
current income free from both federal and state income taxes by investing in
insured municipal bonds. The Delaware Tax-Free Kansas Fund seeks high current
income free from both federal and state income taxes and local intangibles tax
by investing in investment grade municipal bonds.

1. Significant Accounting Policies
The following accounting policies are in accordance with accounting principles
generally accepted in the United States and are consistently followed by the
Funds.

Security Valuation - Long-term debt securities are valued by an independent
pricing service and such prices are believed to reflect the fair value of such
securities. Money market instruments having less than 60 days to maturity are
valued at amortized cost, which approximates market value. Other 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 Funds' Board
of Trustees.

Federal Income Taxes - Each Fund intends to qualify or to continue to qualify as
a regulated investment company and make the requisite distributions to
shareholders. Accordingly, no provision for federal income taxes has been made
in the financial statements. Income and capital gain distributions are
determined in accordance with federal income tax regulations, which may differ
from accounting principles generally accepted in the United States.

Class Accounting - Investment income, common expenses and realized and
unrealized gain (loss) on investments are allocated to the various classes of
the Funds on the basis of daily net assets of each class. Distribution expenses
relating to a specific class are charged directly to that class.

<PAGE>

Use of Estimates - The preparation of financial statements in conformity with
accounting principles generally accepted in the United States requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities at the date of the financial statements and the reported
amounts of revenues and expenses during the reporting period. Actual results
could differ from those estimates.

Other - Expenses common to all funds within the Delaware Investments Family of
Funds are allocated amongst the funds on the basis of average net assets.
Security transactions are recorded on the date the securities are purchased or
sold (trade date). Costs used in calculating realized gains and losses on the
sale of investment securities are those of the specific securities sold.
Interest income is recorded on the accrual basis. Original issue discounts and
market premium are amortized to interest income over the lives of the respective
securities. The Funds declare dividends from net investment income daily and pay
such dividends monthly. Capital gains, if any, are distributed annually.

Certain expenses of the Funds are paid through commission arrangements with
brokers. These transactions are done subject to best execution. The expenses
paid under the above arrangement are included in their respective expense
captions on the Statement of Operations with the corresponding expense offset
shown as "expenses paid indirectly". The amount of these expenses for the period
ended August 31, 2000 are as follows:

Delaware Tax-Free Idaho Fund ............................ $1,177
Delaware Tax-Free Iowa Fund ............................. $  956
Delaware Tax-Free Kansas Fund ........................... $  346

*  Commencement of operations.

5. Lines of Credit
The Funds, along with certain other funds in the Delaware Investments Family of
Funds (the "Participants"), participate in a $375,400,000 revolving line of
credit facility to be used for temporary or emergency purposes as an additional
source of liquidity to fund redemptions of investor shares. The Participants are
charged an annual commitment fee, which is allocated across the Participants on
the basis of each fund's allocation of the entire facility. The Participants may
borrow up to a maximum of one-third of their net assets under the agreement. The
Funds had no amounts outstanding as of August 31, 2000, or at any time during
the period.

6. Credit And Market Risk
The Funds concentrate their investments in securities mainly issued by each
specific states' municipalities. The value of these investments may be adversely
affected by new legislation within the state, regional or local economic
conditions, and differing levels of supply and demand for municipal bonds. Many
municipalities insure repayment for their obligations. Although bond insurance
reduces the risk of loss due to default by an issuer, such bonds remain subject
to the risk that market value may fluctuate for other reasons and there is no
assurance that the insurance company will meet its obligations.
These securities have been identified in the Statements of Net Assets.



                                                                              63

7. Tax Information (Unaudited)
The information set forth below is for each Fund's fiscal year as required by
federal laws. Shareholders, however, must report distributions on a calendar
year basis for income tax purposes, which may include distributions for portions
of two fiscal years of a fund. Accordingly, the information needed by
shareholders for income tax purposes will be sent to them in early 2001. Please
consult your tax advisor for proper treatment of this information.

For the fiscal year ended August 31, 2000, each Fund designates as long-term
capital gains, ordinary income and tax-exempt distributions paid during the year
as follows:

To the Shareholders and Board of Trustees
Voyageur Mutual Funds - Delaware Tax-Free Idaho Fund
Voyageur Mutual Funds - Delaware Tax-Free Iowa Fund
Voyageur Investment Trust - Delaware Tax-Free Kansas Fund
Voyageur Investment Trust - Delaware Tax-Free Missouri Insured Fund
Voyageur Mutual Funds - Delaware Montana Municipal Bond Fund
Voyageur Tax Free Funds - Delaware Tax-Free North Dakota Fund
Voyageur Investment Trust - Delaware Tax-Free Oregon Insured Fund
Voyageur Mutual Funds - Delaware Tax-Free Wisconsin Fund

We have audited the accompanying statements of net assets of Delaware Tax-Free
Idaho Fund, Delaware Tax-Free Iowa Fund, Delaware Tax-Free Kansas Fund, Delaware
Tax-Free Missouri Insured Fund, Delaware Montana Municipal Bond Fund, Delaware
Tax-Free North Dakota Fund, Delaware Tax-Free Oregon Insured Fund and Delaware
Tax-Free Wisconsin Fund (the "Funds") as of August 31, 2000, and the related
statements of operations and statements of changes in net assets for each of the
periods indicated therein, and the financial highlights for each of the periods
presented from January 1, 1997 through August 31, 2000.These financial
statements and financial highlights are the responsibility of the Funds'
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.The financial highlights
for the periods presented through December 31, 1996 were audited by other
auditors whose reports thereon dated February 14, 1997 expressed unqualified
opinions on such financial highlights.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights. Our procedures included
confirmation of securities owned as of August 31, 2000, by correspondence with
the custodian and brokers. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the above listed funds at August 31, 2000, the results of their operations
and changes in their net assets for each of the periods indicated therein, and
their financial highlights for each of the periods presented from January 1,
1997 through August 31, 2000, in conformity with accounting principles generally
accepted in the United States.
