As a precaution, Seattle Parks and Recreation has temporarily closed access to the water at Matthews Beach Park in northeast Seattle due to toxic algae scum in Lake Washington along the shore. Mathews Beach is located at 49th Avenue NE and NE 93rdStreet.
In general, people and pets should not wade or play in the lake, especially where the scum has accumulated, and dogs should not drink from the lake. If there is water contact, it is important to rinse well to remove all algae. For more information on toxic algae and symptoms of toxic poisoning, please visit Washington Department of Health toxic algae website.
