FROM THE TRUSTEES
[GRAPHIC OMITTED: PHOTO OF JOHN A. HILL AND GEORGE PUTNAM III]
Dear Shareholder:
It is a pleasure to greet you in our new roles as Chairman of the
Trustees and President of the Funds. As you know, both of us have been
members of the Board of Trustees for a number of years -- years during
which the global securities markets, the mutual fund industry, and
Putnam itself have experienced tremendous growth and change.
As we look to the future, we are certain that the changes will be
breathtaking in their scope. What will not change is the Trustees'
dedication to serving the best interests of our shareholders.
We welcome the challenges that lie ahead and are confident that Putnam
and your Board will continue to face those challenges successfully as
they have for more than 60 years. We look forward to helping you meet
your financial objectives for many years to come.
Respectfully yours,
/S/ JOHN A. HILL /S/ GEORGE PUTNAM, III

REPORT FROM FUND MANAGEMENT
Brian S. Torpey
For most of the 12 months ended September 30, 2000, the tax-exempt money
market sustained positive momentum. The economy remained strong,
inflation was subdued, and interest rates tended upward. Among other
U.S. financial markets, the equity market experienced growing volatility
amid uneven corporate earnings reports, while the bond market generally
declined in response to rising interest rates. Overall, the environment
for money market funds was favorable, and your fund's recent performance
reflects this.

calculation methods begin on page 5.
* ECONOMIC STRENGTH BEGINS TO WANE; FED POLICY ON HOLD
The annual period began with the U.S. economic engine in full gear.
Plentiful jobs, rising incomes, tame inflation, and stock market gains
put consumers in a buying mood. Indeed, one key indicator of the
economy's positive momentum has been home sales, which have remained
strong over the past six months. In August, existing home sales rose
9.3%. This was the largest gain since June 1999, when sales of existing
homes reached 10.9%. It surprised many analysts, who had expected a rise
closer to 4%.
As the third quarter progressed, clearer evidence of economic slowing
began to emerge. A punishing string of corporate earnings warnings
relentlessly pushed down stock prices, especially among the
much-watched, high-flying technology stocks. Rising oil prices also
began to concern investors, analysts, and consumers. President Clinton
took the unusual step of releasing oil from the nation's petroleum
reserves to help reduce oil prices. Signs of a slowdown have also begun
to emerge in Asia and Europe. However, just after the period closed the
unemployment rate dipped to 3.9% -- a 30-year low and a surprise to
analysts who had been expecting a slight rise and further evidence of an
economic slowdown.
Over the 12-month period, the Federal Reserve Board, concerned that the
strong economy would bring about a rise in inflation, raised its federal
funds rate (the interest rate charged by banks when they loan money to
each other) six times. By May, the tightening cycle appeared to be
ending, and the Fed left rates alone for the rest of the period. Several
reasons account for this shift. First, the Fed saw evidence that the
economy was weakening -- the intended effect of the interest-rate
increases. Second, the euro has been extremely weak against the dollar,
and if the Fed was to raise interest rates further, the euro's weakness
could be exacerbated. Third, oil prices are rising, another potential
drag on the economy. Finally, with the presidential election
approaching, the Fed may have been reluctant to act for fear of
appearing biased toward either party's candidate.
* GROWING DEMAND AND LOW SUPPLY KEEP TAX-EXEMPT MARKET STRONG
Yields on tax-exempt money market securities remained attractive over
the period, especially relative to yields on longer-term tax-exempt
bonds. Although the municipal market has not experienced the inverted
yield curve of the Treasury market (in which yields on short-term
securities are higher than those on longer-term issues), its yield curve
has remained relatively flat. Since intermediate and longer-term bonds
are not offering significantly higher yields than short-term securities,
investors see less potential reward in assuming the greater
interest-rate risks associated with these longer issues.
Partly as a result of their yield advantage, tax-exempt money market
securities have been in high demand over the period. In fact, tax-exempt
money market assets grew by 13.7% over the 12 months ended September 30,
2000. Demand has been particularly strong in states that, like
California, have a high proportion of wealthy individuals in its
Internet and technology business sectors. In many cases, the companies
these people work for go public, providing the investors with a windfall
that many choose to invest at least partially in municipal bonds and
tax-exempt money market securities. Besides higher yields, investors
also appreciate the attractive relative stability of these issues.
With the economy continuing to generate strong tax revenues for many
municipalities, the supply of tax-exempt money market securities has
been lighter than in previous years. Some states, including California,
did not issue short-term debt at all. This supply shortfall, combined
with increased demand, has reduced buying opportunities for your fund.
* FUND MAINTAINS QUALITY FOCUS
Superior quality and capital preservation remain the hallmarks of your
fund's portfolio strategy, and we continue to invest in a wide spectrum
of traditional tax-exempt money market securities. Although the low
supply of tax-exempt securities has increased the challenge of finding
the higher-grade notes we target, we have not compromised our quality
standards. In the current portfolio, all holdings are insured, backed by
letters of credit, or carry the highest available rating from at least
one major rating agency.
Because higher quality securities carry a lower level of risk, they
typically offer slightly lower yields. Consequently, to keep the fund's
yield competitive, we try to keep the fund's dollar- weighted average
maturity (DWAM) at or slightly above the market average. This typically
means a focus on longer-term money market securities, which generally
offer slightly higher yields. The fund's actual DWAM has fluctuated
around the market average for most of the past year, as lack of supply
has limited our buying opportunities. Supply generally improves in the
2nd and 4th quarter of each calendar year. So, over the near term, we
will be looking to lengthen maturities as overall demand wanes, yields
become more attractive, and we work to avoid a difficult reinvestment
period in the first quarter of 2001.
The views expressed here are exclusively those of Putnam Management.
They are not meant as investment advice. Although the described holdings
were viewed favorably as of 9/30/00, there is no guarantee the fund will
continue to hold these securities in the future. An investment in the
fund is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency. Although the fund seeks to
preserve your investment at $1.00 per share, it is possible to lose
money by investing in the fund.

will fluctuate. The principal value on passbook savings and on bank CDs
is generally insured up to certain limits by state and federal agencies.
Unlike stocks, which incur more risk, CDs offer a fixed rate of return.
Unlike money market funds, bank CDs may be subject to substantial
penalties for early withdrawals. After-tax return assumes a 45.22%
maximum combined state and federal income tax rate.

Results for investors subject to lower tax rates would not be as

to the federal alternative minimum tax. Investment income may be
subject to state and local taxes.
Past performance is no assurance of future results and more recent
returns may be more or less than those shown. Fund performance data do
not take into account any adjustment for taxes payable on reinvested
distributions. Investment returns will fluctuate. An investment in the
fund is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency. Although the fund seeks to
preserve your investment at $1.00 per share, it is possible to lose
money by investing in the fund. The fund's holdings do not match those
in the Lipper average. Yield data more closely reflect the current
earnings of the fund.

TERMS AND DEFINITIONS
Total return shows how the value of the fund's shares changed over time,
assuming you held the shares through the entire period and reinvested
all distributions in the fund.
Net asset value (NAV) is the value of all your fund's assets, minus any
liabilities, divided by the number of outstanding shares, not including
any initial or contingent deferred sales charge.
COMPARATIVE BENCHMARKS
Lipper California Tax Exempt Money Market Fund Average, used for
performance comparison purposes, is an arithmetic average of the total
return of all California tax exempt money market mutual funds tracked by
Lipper Analytical Services. Lipper is an independent rating organization
for the mutual fund industry. Lipper rankings vary for other periods.
The fund's holdings do not match those in the Lipper average. It is not
possible to invest directly in an index.
Consumer price index (CPI) is a commonly used measure of inflation; it
does not represent an investment return.
A GUIDE TO THE FINANCIAL STATEMENTS
These sections of the report, preceded by the Report of independent
accountants, constitute the fund's financial statements.
The fund's portfolio lists all the fund's investments and their values
as of the last day of the reporting period. Holdings are organized by
asset type and industry sector, country, or state to show areas of
concentration and diversification.
Statement of assets and liabilities shows how the fund's net assets and
share price are determined. All investment and noninvestment assets are
added together. Any unpaid expenses and other liabilities are
subtracted from this total. The result is divided by the number of
shares to determine the net asset value per share, which is calculated
separately for each class of shares. (For funds with preferred shares,
the amount subtracted from total assets includes the net assets
allocated to remarketed preferred shares.)
Statement of operations shows the fund's net investment gain or loss
for the reporting period. This is determined by adding up all the fund's
earnings -- from dividends and interest income -- and subtracting its
operating expenses. This statement also lists any net gain or loss the
fund realized on the sales of its holdings and -- for holdings that
remain in the portfolio -- any change in unrealized gains or losses over
the period.
Statement of changes in net assets shows how the fund's net assets were
affected by distributions to shareholders and by changes in the number
of the fund's shares. It lists distributions and their sources (net
investment income or realized capital gains) over the current reporting
period and the most recent fiscal year-end. The distributions listed
here may not match the sources listed in the Statement of operations
because the distributions are determined on a tax basis and may be paid
in a different period from the one in which they were earned.
Financial highlights provide an overview of the fund's investment
results, per-share distributions, expense ratios, net investment income
ratios and portfolio turnover in one summary table, reflecting the five
most recent reporting periods. In a semiannual report, the highlight
table also includes the current reporting period. For open-end funds, a
separate table is provided for each share class.
REPORT OF INDEPENDENT ACCOUNTANTS
The Board of Trustees and Shareholders
Putnam California Tax Exempt Money Market Fund
We have audited the accompanying statement of assets and liabilities of
Putnam California Tax Exempt Money Market Fund, including the fund's
portfolio, as of September 30, 2000, and the related statement of
operations for the year then ended, statements of changes in net assets
for each of the years in the two-year period and financial highlights
for each of the years in the two-year period then ended. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits. The
financial highlights for each of the years in the three-year period
ended September 30, 1998 were audited by other auditors whose report
dated November 11, 1998 expressed an unqualified opinion on those
financial highlights.
We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that
we plan and perform our 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. Our procedures included confirmation of securities owned as
of September 30, 2000 by correspondence with the custodian. 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 Putnam California Tax Exempt Money Market Fund as
of September 30, 2000, the results of its operations, changes in its net
assets and financial highlights for each of the years or periods
described above, in conformity with accounting principles generally
accepted in the United States of America.

(RAT) The Moody's or Standard & Poor's ratings indicated are believed to
be the most recent ratings available at September 30, 2000 for the
securities listed. Ratings are generally ascribed to securities at the
time of issuance. While the agencies may from time to time revise such
ratings, they take no obligation to do so, and the ratings do not
necessarily represent what the agencies would ascribe to these
securities at September 30, 2000. Securities rated by Putnam are
indicated by "/P" and are not publicly rated. Ratings are not covered by
the Report of independent accountants.
Moody's Investor Service, Inc. and Standard & Poor's Corp. are the leading
independent rating agencies for debt securities. Moody's uses the designation
"Moody's Investment Grade", or "MIG", for most short-term municipal obligations,
adding a "V" ("VMIG") for bonds with a demand or variable feature; the
designation "P" is used for tax exempt commercial paper. Standard & Poor's uses
"SP" for notes maturing in three years or less, "A" for bonds with a demand or
variable feature.
Moody's Investor Service, Inc.
MIGI/VMIGI = Best quality; strong protection of cash flows, superior liquidity
and broad access to refinancing
MIG2/VMIG2 = High quality; ample protection of cash flows, liquidity support and
ability to refinance
Aaa = Extremely strong capacity to pay interest and repay principal
Aa = Strong capacity to pay interest and repay principal and differs from the higher
rated issues only in a small degree
P-1 = Superior capacity for repayment
P-2 = Strong capacity for repayment
Standard & Poor's Corp.
SP-1+ = Very strong capacity to pay principal and interest
SP-1 = Strong capacity to pay principal and interest
SP-2 = Satisfactory capacity to pay principal and interest
A-1+ = Extremely strong degree of safety
A-1 = Strong degree of safety
A-2 = Satisfactory capacity for timely repayment
(b) The aggregate identified cost on a tax basis is the same.
The rates shown on Floating Rate Bonds (FRB) are the current
interest rates shown at September 30, 2000 which are subject to change
based on the terms of the security.
The rates shown on VRDN's are the current interest rates at
September 30, 2000.
The fund had the following industry group concentrations greater
than 10% at September 30, 2000 (as a percentage of net assets):
Pollution control 24.6%
Capital improvements 15.8
Education 14.9
Water and sewer 11.4

NOTES TO FINANCIAL STATEMENTS
September 30, 2000
Note 1
Significant accounting policies
Putnam California Tax Exempt Money Market Fund (the "fund") is
registered under the Investment Company Act of 1940, as amended, as a
diversified, open-end management investment company. The fund seeks as
high a level of current income exempt from federal income tax and
California personal income tax as is consistent with preservation of
capital, maintenance of liquidity and stability of principal by
investing primarily in a diversified portfolio of short-term California
tax-exempt securities.
The following is a summary of significant accounting policies
consistently followed by the fund in the preparation of its financial
statements. The preparation of financial statements is in conformity
with generally accepted accounting principles and requires management to
make estimates and assumptions that affect the reported amounts of
assets and liabilities of the financial statements and the reported
amounts of increases and decreases in net assets from operations during
the reporting period. Actual results could differ from those estimates.
A) Security valuation The valuation of the funds' portfolio instruments
is determined by means of the amortized cost method as set forth in Rule
2a-7 under the Investment Company Act of 1940. The amortized cost of an
instrument is determined by valuing it at cost originally and thereafter
amortizing any discount or premium from its face value at a constant
rate until maturity.
B) Security transactions and related investment income Security
transactions are accounted for on the trade date (date the order to buy
or sell is executed).
C) Federal taxes It is the policy of the fund to distribute all of its
taxable income within the prescribed time and otherwise comply with the
provisions of the Internal Revenue Code applicable to regulated
investment companies. It is also the intention of the fund to distribute
an amount sufficient to avoid imposition of any excise tax under Section
4982 of the Internal Revenue Code of 1986, as amended. Therefore, no
provision has been made for federal taxes on income, capital gains or
unrealized appreciation on securities held nor for excise tax on income
and capital gains.
D) Interest income and distributions to shareholders Interest is
recorded on the accrual basis. Income dividends are recorded daily by
the fund and are paid monthly to the shareholders.
E) Amortization of bond premium and accretion of bond discounts Premiums
and discounts from purchases of short-term investments are
amortized/accreted at a constant rate until maturity.
Note 2
Management fee, administrative
services and other transactions
Compensation of Putnam Investment Management, Inc. ("Putnam
Management"), the fund's manager, a wholly-owned subsidiary of Putnam
Investments, Inc. for management and investment advisory services is
paid quarterly based on the average net assets of the fund. Such fee is
based on the following annual rates: 0.45% of the first $500 million of
average net assets, 0.35% of the next $500 million, 0.30% of the next
$500 million, 0.25% of the next $5 billion, 0.225% of the next $5
billion, 0.205% of the next $5 billion, 0.19% of the next $5 billion,
and 0.18% thereafter.
The fund reimburses Putnam Management an allocated amount for the
compensation and related expenses of certain officers of the fund and
their staff who provide administrative services to the fund. The
aggregate amount of all such reimbursements is determined annually by
the Trustees.
Custodial functions for the fund's assets are provided by Putnam
Fiduciary Trust Company (PFTC), a subsidiary of Putnam Investments Inc.
Investor servicing agent functions are provided by Putnam Investor
Services, a division of PFTC.
For the year ended September 30, 2000, fund expenses were reduced by
$53,625 under expense offset arrangements with PFTC. Investor servicing
and custodian fees reported in the Statement of operations exclude these
credits. The fund could have invested a portion of the assets utilized
in connection with the expense offset arrangements in an income
producing asset if it had not entered into such arrangements.
Each Trustee of the fund receives an annual Trustee fee, of which $279
has been allocated to the fund, and an additional fee for each Trustees
meeting attended. Trustees receive additional fees for attendance at
certain committee meetings.
The fund has adopted a Trustee Fee Deferral Plan (the "Deferral Plan")
which allows the Trustees to defer the receipt of all or a portion of
Trustees Fees payable on or after July 1, 1995. The deferred fees remain
invested in certain Putnam funds until distribution in accordance with
the Deferral Plan.
The fund has adopted an unfunded noncontributory defined benefit pension
plan (the "Pension Plan") covering all Trustees of the fund who have
served as a Trustee for at least five years. Benefits under the Pension
Plan are equal to 50% of the Trustee's average total retainer and
meeting fees for the three years preceding retirement. Pension expense
for the fund is included in Compensation of Trustees in the Statement of
operations. Accrued pension liability is included in Payable for
compensation of Trustees in the Statement of assets and liabilities.
The fund has adopted a distribution plan (the "Plan") pursuant to Rule
12b-1 under the Investment Company Act of 1940. The purpose of the Plan
is to compensate Putnam Retail Management, Inc., a wholly-owned
subsidiary of Putnam Investments, Inc., for services provided and
expenses incurred by it in distributing shares of the fund. The Plan
provides for payment by the fund to Putnam Retail Management, Inc. at an
annual rate of up to 0.35% of the fund's average net assets. Currently,
no payments are being made under the plan. For the year ended September
30, 2000, Putnam Retail Management, Inc., acting as underwriter receives
proceeds from contingent deferred sales charges that apply to certain
shares that have been exchanged from other Putnam funds. Putnam Retail
Management, Inc., received no monies in contingent deferred sales
charges from such redemptions.
Note 3
Purchase and sales of securities
During the year ended September 30, 2000, cost of purchases and proceeds
from sales (including maturities) of investment securities (all
short-term obligations) aggregated $107,836,301 and $109,314,253,
respectively.
Note 4

At September 30, 2000, there was an unlimited number of shares of
beneficial interest authorized. Transactions in capital shares at a
