Silverwood Lake Cleared for Recreation; Algal Bloom Test Results Fall below Caution Levels

HESPERIA, Calif. - Swimming, boating and other water activities can resume at Silverwood Lake, a State Water Project reservoir in San Bernardino County, according to the Department of Water Resources (DWR).

A no-swimming advisory was issued for Silverwood Lake on August 4 based on tests that found potentially harmful levels of microtoxins. Testing this week revealed those levels have fallen below the caution level.

Sunlight, warm temperatures, nutrients in the water and calm conditions can contribute to algal blooms, which are considered to be harmful if they produce toxins that can affect people and pets when they contact the affected water.

DWR will continue to test the water and will update this advisory if conditions change.

Additional information on harmful algal blooms can be found on these State Water Resources Control Board and Department of Public Health websites:
