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.
