More than just flowers are blooming this summer. The Washington Department of Ecology is currently monitoring lakes across the state to determine the toxin levels of algae blooms, and they are asking swimmers and boaters to be on guard.

An algae bloom turns a clear lake into a pea soup-colored scum, but it can be difficult to know when the bloom is toxic. If residents see evidence of a bloom on a local lake, they are advised to not allow pets or children near the water and to contact the Ecology department.

Currently, Waughop and Clear Lakes in Pierce County, as well as Lone Lake in Island County and Anderson Lake in Jefferson County, have confirmed cases of toxic algae blooms.
