Dreyfus Cash Management Funds

LETTER FROM THE PRESIDENT

Dear Shareholder:

We are pleased to present this semiannual report for the Dreyfus Cash Management
Funds  covering  each  fund' s  six-month reporting period from February 1, 1999
through  July  31,  1999. Inside, you'll find valuable information about how the
funds  were  managed  during  the  reporting  period, including discussions with
Patricia  A.  Larkin,  portfolio  manager for each taxable fund, and Karen Hand,
portfolio    manager    for    each    tax-exempt    fund.

After  remaining  relatively  steady during the first quarter of 1999, yields on
both  taxable  and tax-exempt money market securities rose in the second quarter
in  response  to  expectations  that  the  Federal  Reserve  Board  would  raise
short-term  interest  rates.  On  June  30,  the Federal Reserve raised rates by
one-quarter  of  a  percentage  point  amid  stronger-than-expected  global  and
domestic  economic growth. The Fed's objective in raising rates was to forestall
a  potential  resurgence  of  inflationary  pressures. This increase effectively
reversed  a  portion  of  the  Federal  Reserve's previous rate cuts, which were
implemented  last  fall  in  an  attempt  to  stimulate  global economic growth

Effective  September  8, 1999, it is anticipated that Colleen Meehan will assume
portfolio  management  responsibilities  for  Dreyfus  Municipal Cash Management
Plus,  Dreyfus  New  York Municipal Cash Management, and Dreyfus Tax Exempt Cash
Management.  Ms.  Meehan is a member of Dreyfus' tax-exempt investment team, and
we  would  anticipate  no  changes in the funds' management approach. Ms. Meehan
would succeed Ms. Hand, who resigned her position to pursue a different career.

We  appreciate  your confidence over the past six months, and we look forward to
your    continued    participation.

Sincerely,


[Stephen E. Canter signature]

What is each fund's investment approach?

There are many factors we consider when managing these funds. We closely monitor
the  outlook  for growth and inflation. We also follow overseas developments for
any  influence they may have on the domestic economy. The posture of the Federal
Reserve  Board  is  also  a  key  determinant  in our decision as to how best to
structure the funds.

Generally,  we actively manage the average maturity of the funds in an effort to
take  advantage  of  expected  changes in interest rates based upon our economic
outlook.  For  example, if we believe that interest rates are likely to fall, we
typically  will lengthen our average maturity in order to lock in today's higher
rates.  Conversely,  in  a  rising  interest rate environment, we typically will
shorten  our  maturities  in order to be able to reinvest at higher rates in the
future.

The  Dreyfus  Cash Management and Dreyfus Treasury Cash Management have triple-A
credit  ratings  from Standard & Poor's and Moody's, and to maintain this rating
each fund has a maximum average maturity of 60 days. Dreyfus Treasury Prime Cash
Management  invests solely in U.S. Treasury securities. Dreyfus Government Prime
Cash  Management invests solely in short-term securities issued or guaranteed by
agencies  of  the U.S. government. Dreyfus Government Cash Management invests in
the  same types of government securities as well as repurchase agreements backed
by  such  securities.  Finally,  Dreyfus  Cash Management Plus can invest in the
broadest array of money market securities.

What other factors influenced  each fund's performance?

When the six-month reporting period began on February 1, 1999, evidence began to
emerge  that  economies  around the world had seen the worst of the currency and
credit  crisis  that affected Asian, Russian and Latin American markets over the
preceding  six  months.  In the wake of that market turmoil, the Federal Reserve
had  reduced  short-term  interest  rates in an attempt to provide liquidity and
stimulate economic growth. Its strategy appears to have worked, because concerns
arose    in    the    first     The    Funds



DISCUSSION OF PERFORMANCE (CONTINUED)

quarter of 1999 that global and domestic factors may be pushing the U.S. economy
towards unsustainable growth.

Between  February and May, conflicting economic signals allowed short-term rates
to  remain  relatively  stable while longer-term bond yields rose. Those signals
included  signs  of  economic strength in the consumer sector of the economy and
relative  weakness  in the industrial sector. As a result, most investors saw no
compelling  reason  for the Federal Reserve to either increase interest rates to
dampen growth, or to reduce rates in an attempt to stimulate growth.

In  June,  however,  it became clearer that economic growth in the world's major
industrialized nations was clearly improving. The U.S. economy continued to move
ahead briskly, evidenced by a strong rebound in manufacturing output that showed
signs of gaining momentum. Consumer confidence was at a 30-year high. Employment
was  strong,  with  hourly  wages  rising. Because of concerns that overly rapid
economic  growth  might  lead  to destructive inflationary pressure, the Federal
Reserve  increased  interest  rates  on  June  30 by one-quarter of a percentage
point, effectively offsetting a portion of last fall's rate cuts.

What is each fund's current strategy?

Over  most of the reporting period, the funds benefited from our commitment to a
longer-than-average  maturity.  That' s  because interest rates did not begin to
rise  until  the  second  quarter of the year. Consequently, as long as interest
rates  remained relatively stable, longer maturities enhanced returns by locking
in prevailing yields.

However,  when it became clear that robust economic growth was likely to lead to
higher interest rates, we began to reduce the funds' average maturities in order
to  keep  cash  available  for  higher yielding instruments. Since June, we have
adopted  a  somewhat  less  aggressive  stance,  gradually  reducing the average
maturity  of  our  investments.  In  an  uncertain market with the potential for
further  tightening  at  the  Federal  Reserve's next meeting in late August, we
adopted  this  more  cautious  approach,  while  still  seeking opportunities to
capture additional yield as such opportunities arise.

What is each fund's investment approach?

Our  goal  is to seek as high a level of tax-exempt income as is practical while
maintaining a stable $1.00 share price. This includes income exempt from federal
income taxes and, for the New York fund, New York state and city taxes as well.

To achieve these objectives, we employ two primary strategies. First, we attempt
to  add  value  by  constructing a diverse portfolio of high-quality, tax-exempt
money  market  instruments  that  we  believe are likely to provide high current
yields.  Second,  we actively manage the funds' average maturity in anticipation
of  interest  rate  trends  and  supply-and-demand  changes  in  the  short-term
municipal marketplace.

For   example,   if   we   expect  supply  to  increase  temporarily  when  many
municipalities  issue short-term debt at once -- as they tend to do in July, for
example  -- we may reduce the funds' average maturity to make cash available for
the  purchase  of higher yielding securities. That's because yields tend to rise
if  many  issuers  are  competing  for investor interest. If we expect demand to
surge  at a time when we anticipate little issuance and, therefore, lower yields
- -- as often happens in January -- we may increase the funds' average maturity to
maintain  current  yields  for  as  long as practical. At other times, we try to
maintain  an average maturity that reflects our view of short-term interest rate
trends.

What other factors influenced  each fund's performance?

When the six-month reporting period began on February 1, 1999, evidence began to
emerge that economies around the world had seen the worst of the global currency
and credit crisis. In the wake of that market turmoil, the Federal Reserve Board
had  reduced  short-term  interest  rates  in  an  attempt to stimulate economic
growth. Its strategy appears to have worked, because concerns arose in the first
quarter of 1999 that the U.S. economy might be growing too quickly.

Between  February  and  May,  indications  of  economic strength in the consumer
sector  of  the economy were contradicted by relative weakness in the industrial
sector.  As  a  result,  most investors saw no compelling reason for the Federal
Reserve  to  either increase interest rates to dampen growth, or to reduce rates
to stimulate growth.

In  June,  however,  it became clearer that economic growth in the world's major
industrialized  nations  was clearly improving. In the U.S., consumer confidence
was  at  a  30-year  high.  Employment  was strong, with hourly wages rising. In
response, the Federal Reserve increased interest rates on June 30 by one-quarter
of  a  percentage  point,  effectively  offsetting a portion of last fall's rate
cuts.

                                                                 The Funds



Because  they  have  enjoyed  higher tax revenues during this period of economic
prosperity,  many  municipalities have had less need to borrow. Yet, demand from
investors  seeking  to minimize their income tax liabilities remained high. This
imbalance  between supply and demand contributed to relatively stable short-term
tax-exempt    yields    in    1999.

What is each fund's current strategy?

We  continue to focus on high-quality money market instruments from a wide array
of  tax-exempt  issuers in the national funds, and of course from among New York
exempt issues in the New York fund. Some of the most frequently used instruments
include Variable Rate Demand Notes (VRDNs), which are issued by investment banks
through  the  securitization  of longer-term municipal bonds. With a put feature
attached to each VRDN, of either one or seven days, we believe that VRDNs afford
a  high  degree  of  liquidity  as  well  as  high  quality  to  the  portfolio.
Accordingly,  as  of  July  31,  1999, at least 45% of each fund was composed of
VRDNs.  The remainder was comprised of municipal notes and tax-exempt commercial
paper.

By  adopting  a  longer-than-average  maturity, our strategy has been to capture
higher-than-average  yields for as long as possible while maintaining the fund's
stable share price.

all  dividends  and  distributions.  These  figures  have been derived from each
fund's 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, Dreyfus New York Municipal
Cash  Management,  (each,  a  "fund" and collectively, the "funds") are open-end
management investment companies registered under the Invest- ment 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 charge. 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 July 31, 1999 based on available cash balances left on
deposit:

Dreyfus Tax Exempt Cash Management                                23,816

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.  Economi

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  Manage-  ment  Plus,  Inc.,  Dreyfus
Government Cash Manage- ment 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.

(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.

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

At  July  31,  1999, the cost of investments for Federal income tax purposes 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.
Dreyfus  New York Municipal Cash Management pays its Board members an annual fee
of  $1,000 and an attendance fee of $500 per meeting. These amounts are borne by
the  Manager  as to each fund pursuant to the undertakings in effect. See Note 2
(a).

NOTE 3--Capital Share Transactions:

Each fund (except for Dreyfus Cash Management Plus, Inc.) is authorized to issue
an  unlimited  number  of $.001 par value shares of Beneficial Interest. Dreyfus
Cash Management Plus, Inc. is authorized to issue 15 billion shares of $.001 par
value Common Stock.
