Description In 2007, the Washington Department of Ecology collected biological, chemical, and physical data at 30 randomly selected lakes in Washington State. This study was part of EPA’s National Lake Assessment which encompassed monitoring at 1,028 lakes in the lower 48 U.S. States.

Measurements of environmental stress were evaluated using the reference site approach. This approach involves setting a reasonable expectation, or reference condition, for each measured parameter.

This study showed over 80% of the lake sample population in Washington is in fair or good condition with regard to physical habitat. The results also showed nutrients and chlorophyll-a were the parameters of highest concern.
