EXHIBIT INDEX Exhibit No. Description - ----------- ----------- 99.1 Press Release dated August 22, 2007

                                                                    Exhibit 99.1

American States Water Company and Subsidiary Ratings Raised to 'A' with
                          a 'Stable' Outlook


    SAN DIMAS, Calif.--(BUSINESS WIRE)--Aug. 22, 2007--American States
Water Company (NYSE:AWR) today confirmed that Standard & Poor's
Ratings Services ('S&P') has raised the corporate ratings for American
States Water Company and its primary water utility subsidiary, Golden
State Water Company ('GSWC') to 'A' with a 'Stable' outlook from 'A-'
with a 'Positive' outlook.

    According to S&P's August 22, 2007 press release, "The ratings
upgrade reflects improvements in AWR's financial profile and
regulatory environment, coupled with expectations of strong cash flow
measures and declining debt leverage. AWR's treatment by the
California Public Utilities Commission (CPUC) has become more
supportive with the 2003 changes to the rate filing process and
adoption of a water action plan in 2005 which outlines several
possible policy improvements, including a weather-normalization
mechanism, improved commodity cost recovery, a distribution system
improvement charge, and cost recovery preauthorization for large
projects."

    Commenting on S&P's actions, AWR's President and Chief Executive
Officer Floyd E. Wicks stated, "We are very pleased with S&P's
decision to raise the ratings for both AWR and GSWC. We appreciate
S&P's efforts to understand the positive aspects as well as the
challenging issues confronting the Company and the industry in which
we operate."

    S&P's corporate credit ratings range from AAA (highest rating
possible) to D (rating for default), reflecting S&P's opinion of a
company's overall capacity to meet its financial obligations. Credit
ratings are not recommendations to buy, sell or hold a security and
are subject to change or withdrawal at any time by the rating agency.

    Certain matters discussed in this news release with regard to the
Company's expectations may be forward-looking statements that involve
risks and uncertainties. The assumptions and risk factors that could
cause actual results to differ materially, include those described in
the Company's Form 10-Q and Form 10-K filed with the Securities and
Exchange Commission.
