Helping citizens monitor, protect, manage, and improve lakes in King County

The Lake Stewardship Program provides technical assistance to help citizens monitor, protect, manage and improve the quality of King County lakes. We can assist you in many ways from helping you identify aquatic plants to providing a speaker for your school or community group.  To help, please contact Rachael Gravon, Water Quality Planner or Chris Knutson, Project Manager.

We also offer resource and educational publications, such as the Water Quality Trend Report and the King County Lake Monitoring Report and one-page fact sheets. To learn more, follow the below links.
