News release: Recreational water users urged to be cautious about toxic algal mats in local Rivers
The State Water Resources Control Board (State Water Board) and Sonoma County Department of Environmental Health Services advise caution for anyone who boats, fishes or swims after harmful algal blooms (HABs) were discovered in multiple Sonoma County rivers. Because children and dogs are most susceptible to serious health impacts, it is recommended that they avoid touching any suspicious-looking algal material found in the water or along river banks.
