    Less winter runoff has allowed visitors to enjoy mostly clean water at California beaches, according to a report released Thursday.

    An estimated 93 percent of the 445 beaches along the state's coast that were tested for bacterial pollution from Memorial Day through Labor Day had good to excellent water quality.

    It was the fifth consecutive year that beachgoers have seen incremental improvement in beach water quality during summer months.

    Three percent or 14 beaches that were monitored during the same period last year received poor marks.

    The annual beach report card, issued by the Santa Monica-based environmental group Heal the Bay, studied bacteria levels found in water samples taken by local agencies from near the Oregon state line to the Mexican border. Heal the Bay attributed the improved water quality to back-to-back dry winters in Southern California and infrastructure upgrades.

    Scant rainfall means less urban runoff into the ocean. Most bacterial contamination occurs during winter, when heavy rains overload storm drains and sewage systems, washing pollutants into the sea. Swimming in polluted waters can cause ear infections and gastrointestinal problems.

    Among the state's 10 beaches with the worst water quality, four were in Los Angeles County, the report found.

    Testing showed the dirtiest beach was at the city of Avalon on Santa Catalina Island off Southern California.

    The environmental group said it expects water quality to improve once Avalon completes an upgrade of an aging sewer system that has been blamed for persistent high pollution levels.

    The second-most polluted beach in the state was Cowell Beach in Santa Cruz County.

    The top 10 “Beach Bummers,” these coastal spots received F grades:

    1. Avalon, Catalina Island
    2. Cowell Beach, Santa Cruz
    3. Poche Beach, Orange County
    4. Cabrillo Beach (harborside), LA County
    5. Malibu Pier, LA County
    6. Marina Lagoon, San Mateo County
    7. Doheny State Beach, Dana Point
    8. Redondo Beach Pier, LA County
    9. Windsurfer Circle, San Francisco County
    10. Tijuana River Mouth, San Diego County

    Heal the Bay has been lobbying for the restoration of $10 million in federal funds used to monitor beach water quality.

    The group said many counties in the state depend on those funds to do testing.

    The latest report also includes beaches in the Pacific Northwest where the water quality was excellent in the vast majority of cases.

    Santa Cruz summary:

    The County of Santa Cruz Environmental Health Services monitored 13 shoreline loca - tions frequently enough (at least weekly) to be included in this report, spanning the area from Natural Bridges State Beach downcoast to Rio del Mar Beach.

    Ten of the 13 (77%) beaches in Santa Cruz County received A grades during the summer dry weather period this past year. Capitola Beach west of the jetty scored a fair grade (C grade) during the summer dry period, with poor grades at Cowell Beach at the wharf (F grade) and Cowell Beach Lifeguard Tower (F grade).

    Winter dry weather grades in Santa Cruz County were excellent overall with only one lo - cation receiving lower than a B grade: Capitola Beach west of the jetty (D grade), which also has a history of chronically polluted beach water. Potential pollution sources are currently under investigation.
