This from Seattle parks this afternoon:
‘The level of toxins in the algae at Green Lake has increased and has prompted parks and Public Health officials to close the lake to swimming and water contact for people and dogs.
People and pets should not swim, wade or play in the lake. Dog owners should be especially cautious not to allow animals to go in or drink from the lake. If there is water contact for a pet, it is important to rinse well to remove all algae.
The lake remains open to fishing (though fish should be thoroughly cleaned) and boating in stable boats. Avoid areas of scum when boating.
A warm, dry summer has promoted the algae bloom, and continued warm weather continues to promote it. Blooms have been known to last into November in particularly warm autumns, and typically disappear as the weather gets colder.
For more information on cyanobacteria, please visit Washington Department of Health toxic algae website.
An earlier warning was released on Aug. 22nd.

Citing a toxic blue-green algae bloom, the city this afternoon closed Green Lake to “wading, swimming and “wet-water boating” activities like sailboarding.
Parks officials issued a special caution to dog owners not to even let dogs drink from the lake, citing the presence of a cyanobacterial toxin in amounts far exceeding the Washington Department of Health’s draft recreational guidelines.
“Rather than risk the health of any park user, we’re closing the lake to some activities until we have confirmation that the water is safe,” said Christopher Williams, acting parks superintendent. “The level of toxicity leads us to err on the side of caution to limit the risk of anyone ingesting the water.”
The lake is open to fishing and boating – activities in which users are unlikely to ingest the water. The closure will be in effect until the algae bloom has completed its life cycle. This could be weeks or months, depending on the fall weather and how it affects the algae in the lake.
