Welcome to the freshwater algae site
The purpose of this site is to provide toxin data related to cyanobacteria blooms
in Washington lakes, ponds and streams. Washington State Department of Ecology
(Ecology) uses this site to share the data from their ongoing freshwater algae
Cyanobacteria (or blue-green algae) can produce toxins at levels that are harmful
to humans, pets, domestic animals, and wildlife. There is no way to detect toxins
in an algae bloom except through laboratory analysis. This website provides access
to Ecology's results.
