Citizens have reported seeing a number of “seasonal” blooms of cyanobacteria (blue-green algae) in the Ocean Shores fresh waterway system. The algae blooms, which are usually blue-green, bright blue, grey or tan in color, often give the water a pea soup appearance and may have a foul odor. Blooms commonly occur at this time of year during calm, hot weather in areas of lakes with shallow, slow moving, or still water that is rich in nutrients. The blooms can last up to three weeks and can be pushed around the lake by the wind. Algae blooms are a natural occurrence and cannot be predicted or prevented and will eventually subside.

Press Release

The algae blooms and the waterways will be monitored by the Grays Harbor Department of Health and the City of Ocean Shores until the blooms subside. The public will be advised if a health concern exists. The City recommends that local residents, visitors, and pets minimize water related recreational activities in areas with a visible floating bloom of algae.
