Spokane Regional Health District (SRHD) issued a harmful algae bloom (HAB) alert for West Medical Lake on August 2, 2026, after tests detected potentially harmful cyanobacteria levels. The alert advises stopping all recreational activities until further notice, as the algae can cause skin rashes, respiratory issues, and more severe symptoms if ingested. SRHD monitors water quality weekly and will update signage once toxicity levels are safe. Residents are encouraged to check the Washington State Toxic Algae website for current status.
