JOINT LETTER TO SHAREHOLDERS

Dear Shareholder:

  We  are  pleased  to  provide  you  with  the  annual reports for Dreyfus Cash
Management,   Dreyfus  Cash  Management  Plus,  Inc.,  Dreyfus  Government  Cash
Management,  Dreyfus  Government  Prime  Cash  Management, Dreyfus Treasury Cash
Management  and  Dreyfus  Treasury  Prime Cash Management, each for the 12-month
period  ended  January 31, 1999. Please see the accompanying table at the end of
this letter for the performance of each Fund.

ECONOMIC REVIEW

  The  U.S. economy remained strong in 1998 in spite of economic turmoil in Asia
and  Russia.  There  were two main reasons: First, consumer spending was strong,
backed  by  healthy  real wage and salary income and the wealth effect from high
asset  prices.  Second,  technology  spending  was  quite strong even as capital
spending in the older industries showed signs of cooling late in the year.

  The  Fed  stood  pat  with  an unchanged Federal Funds rate for the first nine
months  of  1998,  but  began to ease rates on September 30. The trigger for its
doing so was a financial crisis brought on by defaults. Despite the fact that an
International Monetary Fund program was in place, Russia defaulted in midsummer.
As the prices of illiquid assets owned by leveraged hedge funds, brokerage firms
and  banks  dropped  sharply, fear in financial circles escalated. The Fed broke
the momentum of financial stress by easing rates on three successive occasions.

The period of financial crisis was brief enough that little damage was done to
the  U.S.  economy  in  1998, as yet another year of above-trend economic growth
with quiescent inflation was recorded.

The U.S. and continental Europe experienced both good results and bad from the
Asian  financial  crisis. In this country, the housing and consumer sectors were
beneficiaries,  while the industrial sector was weakened by the Asian recession.
Low inflation permitted credit to ease in both Europe and the U.S.

  In  1998,  the  global  economy  survived a triple financial crisis focused on
Japan,   on   emerging   market   countries   and  on  hyperleveraged  financial
institutions.  Overseas, excess capacity persists in many industries after years
of  high  capital  spending  followed  by the onset of weakness in world demand.
Fortunately,  the  U.S.  has  led  the  world  in making the transition from the
traditional  industries  to  the  new  growth  industries such as biotechnology,
software,   hardware  and  the  Internet.  This  contributed  to  the  favorable
combination  of  a  low  unemployment  rate  and  low  inflation  in the U.S., a
performance  which  has strengthened the forces for more efficient allocation of
capital elsewhere in the world.

MARKET ENVIRONMENT/PORTFOLIO FOCUS

  The  economic  forces described above drove down interest rates in late summer
and  early  fall. Later in the year there was a modest increase in rates. One of
its  effects  was  to  change the yield curve from a negatively sloping one to a
positively  sloping  one.  In  this  normal  configuration,  longer-term  yields
exceeded those of the shorter-term instruments.

  A  flight  to safety by global investors was the force that most affected U.S.
interest  rates last fall. In recent weeks, as the domestic economy continued to
demonstrate  exceptional  strength, rates edged higher. One factor affecting the
U.S.  interest  rates  has  been  the  rise in interest rates in Japan. This has
brought  about  some  repatriation  of  investment  funds  to  that  country. In
addition,  the  introduction  of the Euro currency at the start of the new year,
which  was  well  received,  put  some  downward pressure on the U.S. dollar and
conversely, upward pressure on yields.

Investor fears of worldwide financial turmoil seemed to have receded recently.
Currently,  prices  and  rates in the money market appear to be reacting more to
underlying  economic  forces  than  to  such market psychology factors. This, of
course,   can   be   constructive  for  investors  in  short-term  money  market
instruments.

The fact that the Federal Reserve Open Market Committee lowered interest rates
three   times   between   late   September   and  year-end  has  been  a  strong
confidence-building  factor  in  the  markets.  Currently,  we expect the Fed to
remain in a "wait and see" mode for the near term.

During the reporting period, we lengthened the average portfolio maturities in
anticipation  of  possible  declining  interest rates. With the domestic economy
demonstrating much resilience as we move forward in 1999, there are likely to be
investment opportunities arising. We will continue to monitor these developments
in  the marketplace, including interest rates, in seeking to maximize the yields
to the funds.

         Very truly yours,

Dear Shareholder:

Cash Management Plus, Dreyfus New York Municipal Cash Management and Dreyfus Tax
Exempt  Cash  Management,  each  for the 12-month period ended January 31, 1999.

performance  which  has strengthened the forces for more efficient allocation of
capital  elsewhere  in  the  world. As 1999 began, the U.S. economy continued to
exhibit surprising strength.

MARKET ENVIRONMENT/PORTFOLIO OVERVIEW

  Throughout  the  fall,  the  short-term municipal market continued to feel the
effects  of  the diminished supply of new issuance during the summer months. The
overall  lack of availability of suitable investments in the one-year range held
yields  down  for  most  of the period. As a result of the relatively flat yield
curve  that  existed,  we  utilized  the  commercial  paper  market in all three
tax-exempt  Cash  Management Funds, as a means of locking in attractive rates in
the 60- to 90-day range without having to extend out a full year.

  As  year-end  approached,  we were poised to take advantage of seasonal market
weakness  and  extend  the Funds' average maturities when possible. However, the
short-term  municipal market's weakness in late December was slight and afforded
us  less  opportunity than in prior years. This, coupled with the lack of supply
of  high-quality  tax-exempt  paper, hindered our ability to extend the Funds to
the  desired  60-plus  day range. This task was even more difficult when seeking
appropriate  New  York-exempt  investments,  which led to a shorter Fund average
maturity  of less than 40 days. When possible, we selectively purchased one-year
notes  issued  by  those municipalities which provided competitive market yields
and which met the high standards required by our internal investment guidelines.
We  will  continue to search for those similar one-year investment opportunities
which  will  lock  in  higher  rates for the Funds while providing an attractive
return  to  the tax-exempt investor. As always, we will structure the portfolios
in an attempt to maximize current yield while maintaining our commitment to high
quality tax-exempt investments.

          Very truly yours,

NOTES TO FINANCIAL STATEMENTS

NOTE 1--SIGNIFICANT ACCOUNTING POLICIES:

  Dreyfus   Cash   Management,  Dreyfus  Cash  Management  Plus,  Inc.,  Dreyfus
Government  Cash  Management,  Dreyfus Government Prime Cash Management, Dreyfus
Treasury  Cash  Management,  Dreyfus  Treasury  Prime  Cash  Management, Dreyfus
Municipal  Cash  Management Plus, Dreyfus Tax Exempt Cash Management and Dreyfus
New  York  Municipal  Cash  Management,  (each,  a  "Fund" and collectively, the
" Funds" ) are  open-end  management  investment  companies registered under the
Investment  Company Act of 1940, as amended (the "Act"). Dreyfus Government Cash
Management  and  Dreyfus  Government  Prime  Cash Management are each a separate
series  of  Dreyfus  Government  Cash  Management  Funds  (the  "Company") which
currently  offers  two  series.  Each  Fund's investment objective is to provide
investors  with  as  high  a  level  of current income as is consistent with the
preservation  of  capital  and  the maintenance of liquidity and, in the case of
Dreyfus  Municipal  Cash  Management Plus and Dreyfus Tax Exempt Cash Management
only,  which  is exempt from Federal income tax, and, in the case of Dreyfus New
York  Municipal  Cash  Management  only,  which is exempt from Federal, New York
State  and  New  York City income taxes. The Dreyfus Corporation (the "Manager")
serves  as each Fund's investment adviser. The Manager is a direct subsidiary of
Mellon Bank, N.A.

  Premier  Mutual  Fund Services, Inc. (the "Distributor") is the distributor of
each  Fund' s  shares,  which are sold without a front end sales load. Each Fund
offers  the  following  classes  of shares: Institutional Shares, Administrative
Shares,  Investor Shares and Participant Shares. Administrative Shares, Investor
Shares  and Participant Shares are subject to a Service Plan adopted pursuant to
Rule  12b-1  under  the  Act.  Other differences between the classes include the
services  offered  to  and  the  expenses borne by each class and certain voting
rights.

It is each Fund's policy to maintain a continuous net asset value per share of
$1.00;  each  Fund  has  adopted  certain  investment,  portfolio  valuation and
dividend and distribution policies to enable it to do so. There is no assurance,
however,  that  any  Fund  will be able to maintain a stable net asset value per
share of $1.00.

  Each  Fund' s  financial  statements are prepared in accordance with generally
accepted accounting principles which may require the use of management estimates
and assumptions. Actual results could differ from those estimates.

  (A)  PORTFOLIO  VALUATION:  Investments  in securities are valued at amortized
cost,  which  has  been  determined by the Fund's Board Members to represent the
fair value of each Fund's investments.

(B) SECURITIES TRANSACTIONS AND INVESTMENT INCOME: Securities transactions are
recorded  on  a  trade  date  basis.  Realized  gain  and  loss  from securities
transactions  are  recorded  on  the  identified  cost  basis.  Interest income,
adjusted   for   amortization   of  premiums  and  original  issue  discount  on
investments, is earned from settlement date and recognized on the accrual basis.
Cost  of  investments  represents amortized cost. Under the terms of the custody
agreement,  each  Fund  receives  net  earnings  credits based on available cash
balances  left  on  deposit.  The  following Funds received net earnings credits
during  the  period ended January 31, 1999 based on available cash balances left
on deposit:



     Dreyfus Government Prime Cash Management  . . . . . . .  . .$    3,543

     Dreyfus Municipal Cash Management Plus  . . . . . . . .  . . $  23,498

     Dreyfus Tax Exempt Cash Management  . . . . . . . . . .  . . .$103,150

Income earned under this arrangement is included in interest income.

  Dreyfus  New  York  Municipal  Cash Management follows an investment policy of
investing  primarily  in  municipal  obligations  of one state. Economic changes
affecting  the  state  and  certain  of its public bodies and municipalities may
affect  the  ability  of  issuers  within the state to pay interest on, or repay
principal of, municipal obligations held by the Fund.

  Dreyfus   Cash   Management,  Dreyfus  Cash  Management  Plus,  Inc.,  Dreyfus
Government  Cash  Management and Dreyfus Treasury Cash Management may enter into
repurchase  agreements with financial institutions, deemed to be creditworthy by
the  Fund' s  Manager,  subject  to the seller's agreement to repurchase and the
Fund' s  agreement  to  resell  such securities at a mutually agreed upon price.
Securities  purchased  subject  to  repurchase agreements are deposited with the
Fund' s  custodians and, pursuant to the terms of the repurchase agreement, must
have  an  aggregate  market  value greater than or equal to the repurchase price
plus  accrued  interest  at all times. If the value of the underlying securities
falls  below  the  value of the repurchase price plus accrued interest, the Fund
will  require  the  seller to deposit additional collateral by the next business
day. If the request for additional collateral is not met, or the seller defaults
on  its  repurchase  obligation,  the  Fund  maintains  the  right  to  sell the
underlying  securities  at market value and may claim any resulting loss against
the seller.

  (C)  EXPENSES:  With regards to the Company, expenses directly attributable to
each  series  are  charged  to  that  series'  operations;  expenses  which  are
applicable to both series are allocated between them.

  (D)  DIVIDENDS  TO  SHAREHOLDERS:  It  is  the  policy of each Fund to declare
dividends  from  investment  income-net on each business day. Such dividends are
paid monthly. Dividends from net realized capital gain are normally declared and
paid  annually, but each Fund may make distributions on a more frequent basis to
comply  with the distribution requirements of the Internal Revenue Code of 1986,
as  amended  (the  "Code" ). To the extent that net realized capital gain can be
offset  by  capital  loss  carryovers,  it  is  the  policy  of each Fund not to
distribute such gain.


NOTES TO FINANCIAL STATEMENTS (CONTINUED)

(E) FEDERAL INCOME TAXES: It is the policy of each Fund to continue to qualify
as  a  regulated  investment  company,  if  such  qualification  is  in the best
interests  of  its  shareholders, by complying with the applicable provisions of
the  Code  and  to make distributions of taxable income sufficient to relieve it
from substantially all Federal income and excise taxes.

  The  following summarizes each Fund's unused capital loss carryovers available
for  Federal  income  tax  purposes  to be applied against future net securities
profits, if any, realized subsequent to January 31, 1999. The carryover does not
include net realized securities losses from November 1, 1998 through January 31,
1999  which  are  treated, for Federal income tax purposes, as arising in fiscal
2000:

was substantially the same as the cost for financial reporting purposes (see the
Statements of Investments).

NOTE 2--MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES:

  (A)   Pursuant  to  separate  management  agreements  with  the  Manager,  the
management fee of each Fund is computed at the annual rate of
 . 20  of  1% of the value of such Fund's average daily net assets and is payable
monthly.

  Unless  the  Manager  gives a Fund's investors 90 days notice to the contrary,
the  Manager,  and  not the Fund, will be liable for Fund expenses (exclusive of
taxes,  brokerage, interest on borrowings and extraordinary expenses) other than
the following expenses, which will be borne by the Fund: the management fee, and
with   respect  to  the  Fund' s  Administrative  Shares,  Investor  Shares  and
Participant Shares, Rule 12b-1 Service Plan expenses.

(B) Under each Fund's Service Plan (the "Plan") adopted pursuant to Rule 12b-1
under  the  Act,  relating  to  its  Administrative  Shares, Investor Shares and
Participant  Shares,  each  Fund (a) reimburses the Distributor for distributing
such  classes of shares and (b) pays the Manager, Dreyfus Service Corporation, a
wholly-owned  subsidiary  of  the  Manager,  and their affiliates (collectively,
" Dreyfus") for advertising and marketing relating to such classes of shares and
for  providing certain services relating to shareholder accounts in such classes
of  shares,  such  as  answering  shareholder  inquiries  regarding the Fund and
providing reports and other information, and services related to the maintenance
of  shareholder  accounts ("Servicing"), at an aggregate annual rate of .10, .25
and  .40  of  1%  of the value of the average daily net assets of Administrative
Shares,   Investor   Shares  and  Participant  Shares,  respectively.  Both  the
Distributor and Dreyfus may pay one or more Service Agents (a securities dealer,
financial  institution  or  other  industry  professional) a fee in respect of a
Fund' s  Administrative  Shares, Investor Shares and Participant Shares owned by
shareholders  with  whom  the  Service Agent has a Servicing relationship or for
whom  the  Service Agent is the dealer or holder of record. Both the Distributor
and  Dreyfus  determine  the amounts, if any, to be paid to Service Agents under
the  Plan  and the basis on which such payments are made. The fees payable under
each Plan are payable without regard to actual expenses incurred.

(C) Each Fund (except for Dreyfus New York Municipal Cash Management) pays its
Board members an annual fee of $3,000 and an attendance fee of $500 per meeting.
