                         California Water Service Group
              Notes to Condensed Consolidated Financial Statements

1.   Due to the seasonal nature of the water  business,  the results for interim
     periods may not be indicative of the results for a twelve-month period.

2.   The  interim  financial  information  is  unaudited.   In  the  opinion  of
     management,  the accompanying financial statements reflect all adjustments,
     which are  necessary  to provide a fair  statement  of the  results for the
     periods covered.  The adjustments consist of normal recurring  adjustments.
     Certain prior years' amounts have been  reclassified,  where necessary,  to
     conform to the current presentation.

3.   Basic  earnings per share is  calculated by dividing  income  available for
     common  stockholders  by the  weighted  average  number  of  common  shares
     outstanding during the period.  Diluted earnings per share is calculated by
     dividing income  available for common  stockholders by the weighted average
     number of common  shares  outstanding  plus  potentially  dilutive  shares.
     Income available for common  stockholders is determined by subtracting from
     net income  dividends  paid on  preferred  stock which were $38,000 for the
     quarter  ended June 30, 2001 and $76,000 for the six months  ended June 30,
     2001. The difference  between basic and diluted  weighted average number of
     common shares  outstanding  is the effect of dilutive  common stock options
     outstanding.

4.   Refer to the  Annual  Report on Form 10-K for the year ended  December  31,
     2000  for  a  summary  of  significant  accounting  policies  and  detailed
     information regarding the financial statement presentation.

5.   The Company  operates  primarily in one business  segment  providing  water
     utility services.

6.   In July 2001, the Financial Accounting Standards Board issued Statement No.
     141,  "Business  Combinations",  and Statement No. 142, "Goodwill and Other
     Intangible  Assets".  Statement  141 requires  that the purchase  method of
     accounting be used for all business  combinations  initiated after June 30,
     2001 as well as all purchase method business  combinations  completed after
     June 30, 2001.  Statement 141 also  specifies  conditions  that  intangible
     assets acquired in a purchase method business  combination  must meet to be
     recognized and reported  apart from goodwill.  Statement 142 specifies that
     goodwill and intangible  assets with  indefinite  useful lives no longer be
     amortized,  but  instead  be tested for  impairment  at least  annually  in
     accordance  with  the  provisions  of  Statement  142.  Statement  142 also
     requires that intangible assets with determinable useful lives be amortized
     over their useful lives to their estimated  residual  values,  and reviewed
     for impairment in accordance  with Statement No. 121,  "Accounting  for the
     Impairment of Long-Lived  Assets and for  Long-Lived  Assets to be Disposed
     of".


     The  Company  is  required  to  adopt  the   provisions  of  Statement  141
     immediately, except with regard to business combinations initiated prior to
     July  1,   2001   that  it   expects   to  be   accounted   for  using  the
     pooling-of-interests  method. Statement 142 is effective for the Company on
     January 1, 2002.

     The Company has not yet  determined  the impact the adoption of  Statements
     141 and 142 will have on its financial position or results of operations.









Item 2

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

FORWARD LOOKING STATEMENTS

         This Form 10Q, contains forward-looking  statements intended to qualify
for  "safe  harbor"  within  the  meaning  of the  Federal  securities  laws  as
established  by the  Private  Securities  Litigation  Reform  Act of 1995.  Such
statements  are  based  on  currently   available   information,   expectations,
estimates,   assumptions  and  projections,   and  management's  judgment  about
California Water Service Group (Company), the water utility industry and general
economic  conditions.   Words  such  as  "expects,   intends,  plans,  believes,
estimates,  anticipates" or variations of such words or similar  expressions are
intended to identify forward-looking  statements. The forward-looking statements
are not guarantees of future  performance.  Actual  results may vary  materially
from what is contained in a forward-looking statement. Factors which may cause a
result  different  than  expected  or  anticipated  include:   governmental  and
regulatory  commissions'  decisions,  the timeliness of regulatory  commissions'
actions  concerning rate relief, new legislation,  electric power  interruption,
increases in  suppliers'  prices and the  availability  of supplies,  changes in
environmental compliance requirements, acquisitions, the ability to successfully
implement business plans,  changes in customer water use patterns and the impact
of weather on operating  results,  especially  as it impacts  water  sales.  The
Company  assumes no  obligation  to provide  public  updates of  forward-looking
statements.

RESULTS FOR THE SECOND QUARTER

         Second  quarter  net income  was  $5,764,000,  equivalent  to $0.37 per
common share on a diluted basis compared to the $5,753,000 or $0.38 per share on
a diluted basis last year.  Operating  revenue  increased 2% from $65,948,000 in
2000 to  $66,958,000.  Cooler  weather,  especially  in the Southern  California
service areas,  had a negative  impact on second quarter  revenue.  Revenue from
existing  customers declined $818,000 as usage per customer was lower this year.
Offsetting the decline in usage was  $1,171,000 of additional  revenue from rate
increases and $657,000 of additional revenue from 7,200 new customers.

     Decreased consumption by existing customers                  ($  818,000)
     Rate increases                                                 1,171,000
     Usage by new customers                                           657,000
                                                                  -----------
          Net revenue increase                                    $ 1,010,000
                                                                  ===========

         Total  operating  expenses  increased 3%. The second  quarter last year
included $1,775,000 of non-recurring  expenses related to the Dominguez Services
Corporation merger that was completed in May 2000.


         Water  production  was  4%  lower;  however,  water  production  costs,
consisting of purchased  water,  purchased  power and pump taxes,  increased 1%.
Water production costs are the largest  components of total operating  expenses.
Together  these  costs  accounted  for 45% of  total  operating  expenses.  Well
production  provided 52% of the water supply,  47% was purchased  from wholesale
suppliers and the balance was developed from surface supplies  processed through
the  Company's  two surface  water  treatment  plants.  The  components of water
production costs and the changes from last year are shown in the table below:

                                               2001 Cost          Change
                                             -----------       -----------
         Purchased water                     $20,135,000        ($196,000)
         Purchased power                       4,587,000           647,000
         Pump taxes                            1,803,000         (260,000)
                                             -----------       -----------
              Total                          $26,525,000          $191,000
                                             ===========       ===========

         Purchased   water  rates  charged  by  wholesalers   increased  in  six
California districts. Despite the increases,  purchased water cost decreased due
to credits received from two wholesale suppliers and a decline in purchases as a
result of reduced customer demand.  Pump taxes decreased because of less pumping
in districts where pump taxes are incurred.

         June was the first month fully impacted by California's higher electric
rates.  Compared to last year, the Company's California electric suppliers' rate
rose an  average of 48%.  For the  quarter,  the  additional  electric  cost was
$647,000. The Company expects that increases in electric rates will be recovered
from  customers  through  established  California  Public  Utilities  Commission
("Commission" or "CPUC") procedures,  although on short-term basis there will be
a regulatory lag in recovering the higher costs.  Authorization  for the Company
to  increase  rates to recover  the higher  electric  costs is  expected  at the
Commission's August 23, 2001 meeting.

          Also increasing other operations expense was the impact of the general
wage  increase  that was  effective at the start of the year,  additional  hours
worked and increases in related employee benefits.

         Maintenance   expense   increased   $500,000  due  to  additional  work
necessitated  by  water  main and  service  line  repairs,  along  with  work at
wellsites.

         Federal and state  income  taxes  increased  $403,000  due to increased
income.

         Net other income  increased  $1,186,000  primarily due to the sale of a
surplus  real estate  property  in the South San  Francisco  district.  The sale
increased other income by $990,000.  Another real estate transaction is expected
to be completed  during 2001 that will provide pretax income of approximately $3
million.

         Interest  expense  on  long-term  debt rose  $260,000  over the  second
quarter of 2000  because of the  issuance  in October  2000 of the $20  million,
Series C 8.15% senior notes.  Other interest  expense  declined  slightly.  Even
though  borrowings  under the bank  short-term  line of credit  were higher this
year, interest rates were lower resulting in the reduced expense.


RESULTS FOR THE SIX MONTHS

         Net income  for the six months  ending  June 30,  2001 was  $5,985,000,
equivalent  to $0.39 per common share on a diluted  basis  compared to the $0.48
per common  share on a diluted  basis  earned for the same period last year.  As
discussed below, the earnings  comparison was impacted by this year's gains from
the program to sell surplus real estate and last year's Dominguez merger costs.

         Operating  revenue  increased  $1,307,000 to  $113,966,000.  The higher
revenue was  primarily  due to rate  increases  and revenue from new  customers.
Since January 1, 2001, 3,800 new customers have been added.  Average consumption
per  metered  customer  decreased  2% from last  year and  average  revenue  per
customer  decreased $1.18. A breakdown of the net increase in operating  revenue
is accounted for in the following table:

            Decreased consumption by existing customers          ($1,833,000)
            Rate increases                                         2,028,000
            Usage by new customers                                 1,112,000
                                                                 -----------
                   Net revenue increase                          $ 1,307,000
                                                                 ===========

         Total operating expenses increased 3%.

         Water  production was 4% less than last year. Well production  provided
50% of the supply with 49% purchased  from  wholesale  suppliers and 1% produced
through  the  treatment  plants.  Despite  the  decrease  in  production,  water
production costs increased  $640,000 mainly due to wholesale water suppliers and
electricity  price  increases.  Refer to the section titled  "California  Energy
Situation"  for further  discussion of electric  costs.  The components of water
production expense and the changes from last year are shown in the table below:

                                            2001 Cost                Change

         Purchased power                    7,019,000              1,023,000
         Pump taxes                         2,651,000               (517,000)
                                        -------------         ---------------
                  Total                   $42,818,000               $640,000
                                        =============         ===============

         In  addition  to  water  production  costs,  other  operations  expense
categories  increased  $2,289,000.  During  2000,  $1,980,000  in  non-recurring
expenses  related to the  Dominguez  merger were  incurred.  Operation  expenses
increased  due to the 3% wage  increase  that was  effective at the start of the
year and the resulting increase in employee benefits costs.

         Maintenance  expenses  were  higher  by  $244,000  due to  work at pump
stations,  and more main and service line  repairs.  Fewer  expenses  related to
water treatment equipment were incurred.


         Depreciation  and  amortization  expense  increased  due  to a  greater
depreciable plant investment.

         Federal and state  income  taxes were lower due to a decline in taxable
income.

         Net other income was $2,202,000  compared to $952,000 last year.  Other
income in 2001 includes  $1,140,000 from two surplus property sales.  There were
no property sales recorded in 2000.

REGULATORY MATTERS

         The Company filed a Notice of Intent with the CPUC in July 2001 stating
that it is  preparing  to file  General  Rate  Case  (GRC)  applications  for 16
California Water Service Company districts.  The applications are expected to be
file in September 2001. The districts  represent  about 70% of total  customers.
Under the Commission's  guidelines for processing GRC  applications,  Commission
decisions would be expected in the second quarter of 2002. However,  the Company
and other water utilities have experienced delays in obtaining rate decisions as
the  Commission  has  not  adhered  to  its  processing   guidelines  in  recent
proceedings.

         As noted  elsewhere in this report,  the Company  filed for offset rate
recovery of the higher California  electric costs in May and expected a decision
in June. That decision is now expected in late August. If approved, it would add
about $6.5 million in additional revenue.

         A decision for the Company's GRC  applications  that were filed in July
2000 to increase rates in three California  districts was expected in the second
quarter  2001.  A decision is now  expected in  September  2001.  If approval is
received, the expected increase in 2001 revenue is estimated at $1,000,000.

         The  Company  filed with the  Commission  in May 2001 for  recovery  of
certain general office expenses.  If approved,  the estimated increase in annual
revenue will be  approximately  $5.9  million.  A  Commission  decision had been
expected in 2001, but is not now expected until mid-2002.

LIQUIDITY

         Short-term bank  borrowings were  $32,000,000 at June 30, 2001 compared
to $14,598,000 at the end of last year.  Additional  short-term  bank borrowings
will be  necessary  during  the third  quarter to fund the  quarterly  dividend.
Following  that  payment,  the  Company  expects  to  generate  cash  flow  from
operations to repay a portion of the  short-term  bank  borrowings.  A long-term
debt financing is expected in the second half of 2001.

         The Company is completing the  syndication of its short-term  bank line
of credit  agreement among two banks.  The total amount  available under the new
arrangement is expected to be $60 million compared to the current agreement that
provides for a $50 million  limit.  The new agreement is expected to be in place
by mid-August.

         On May 15, 2001, the second quarter common and preferred dividends were
paid.


         The third  quarter  common  dividend will be paid on August 15, 2001 at
$0.27875  per share as  approved  by the Board of  Directors  at their July 2001
meeting.  This is the 227th consecutive  quarterly dividend paid by the Company.
Annualized,  the 2001 dividend rate is $1.115 per common share compared to $1.10
in 2000. Based on the 12-month earnings per share at June 30, 2001, the dividend
payout ratio is 92%.

         About 10% of the  outstanding  shares  participate in the  reinvestment
program  under the  Company's  Dividend  Reinvestment  and Stock  Purchase  Plan
("Plan").  No new common  shares were issued  under the Plan during the quarter.
Shares required for the dividend  reinvestment  and stock purchase option of the
Plan were  purchased on the open market.  Shares are also  purchased on the open
market to fulfill the  requirements of the Company  sponsored  Employee  Savings
Plan (401(k)). Purchases for this plan are made on a biweekly basis.

         Book value per common share was $12.98 at June 30, 2001.

         During the quarter,  utility plant expenditures totaled $22,339,000 for
additions to and replacements of utility plant. On a year-to-date  basis,  plant
expenditures  have been  $27,245,000.  The  plant  expenditures  were  funded by
operations, short-term bank borrowings and developers.

WATER SUPPLY

         The  Company  believes  that its  various  sources of water  supply are
sufficient to meet customer demand for the remainder of the year.  Historically,
roughly half of the water source is purchased from wholesale  suppliers with the
other half pumped from wells.  A small portion is developed  through three local
surface treatment plants.

         Storage in state  reservoirs was 98% of historic average as of June 30,
2001, and groundwater levels remain adequate.  While below historic average, the
mountain  snowpack  will provide  runoff to streams and  reservoirs  as it melts
during the summer months.

CALIFORNIA ENERGY SITUATION

         In  recent  months,   the  California   energy  crisis  has  been  well
publicized.  The CPUC authorized electric suppliers to increase rates in January
followed by a larger  increase  effective  in June.  Compared to last year,  the
increase in the Company's purchased power rates is approximately 48%.

         During  the  second  quarter,  California  was  able to  avoid  rolling
electric  blackouts.   The  Company  continues  its  efforts  to  use  power  as
efficiently  as possible  and at the lowest cost to its  customers.  The Company
maintains  backup power  systems to continue  water  service to customers if the
power  companies'  supplies are  interrupted.  Many  wellsites are equipped with
emergency   electric   generators.   The  generators  are  designed  to  produce
electricity to keep wells  operating  during power  outages.  Storage tanks also
provide customers with water during blackout periods.


ACCOUNTING PRONOUNCEMENTS

         Refer  to  Note 6 of the  Notes  to  Condensed  Consolidated  Financial
Statements for information  regarding issuance of Financial Accounting Standards
Board  Statement  No.  141,  "Business  Combinations",  and  Statement  No. 142,
"Goodwill and Other Intangible Assets".

MARKET RISK

         The  Company  does not  hold,  trade in or issue  derivative  financial
instruments and therefore is not exposed to risks these instruments present.

         The Company's  market risk to interest rate exposure is limited because
the cost of  long-term  financing,  including  interest  costs,  are  covered in
consumer  water rates as approved by the  Commission.  The Company does not have
foreign  operations,  therefore,  it does not have a foreign  currency  exchange
risk.

         The  Company's  sensitivity  to  commodity  prices is most  affected by
changes in purchased water and purchased power costs.  Through the  Commission's
balancing account  procedures,  increases in purchased water and purchased power
costs can be passed on to consumers.  The Company  manages other commodity price
exposure through the duration and terms of its vendor contracts.
