Detailed search for your lake
This database contains the most current toxicity data available. All instances of values above the recreational guidelines are kept
as up to date as possible, but values below the guidelines may be somewhat delayed in entry.Since there is a lag time from the
date of sample to the date of analysis, be sure to check the sample date when looking at data or before
you use the lake. Remember to use caution and avoid scums. "When in doubt, stay out!"
Your local jurisdiction may have more specific information about your lake. Questions? Contact
toxicalgae at Department of Ecology.
If a lake is not listed, it has not been tested for toxic algae through the Ecology program.
The pins on the map represent the center of small lakes, regardless of where the sample was taken. To find
more precise location information, download the toxin data and click the "view scum info" link. That is where
specific sampling location information will be if it was provided. On larger lakes, (such as Lake Washington,
Moses Lake and Potholes) pins represent the location of the sample if provided.
