Silver Lake - Water Testing, Beach Guidance
Testing
Town Beach is routinely tested every Monday during the Beach season and results are posted on Tuesdays.
A beach will be closed if the bacteria test exceeds either of these limits: 235 E.Coli/100 ml. of water in a single sample, or a geometric mean of 126 in the last 5 consecutive samples.
A significant algae bloom can cause a closure of the beach.
Note: A test that appears to be an anomaly will be retested as soon as possible for confirmation.
A beach closure will not be implemented based on a single test which appears to be an anomaly.
