Volunteer information and opportunities
Lake Stewardship in King County
Volunteer lake monitors are an invaluable asset to the Lake Stewardship Program- their efforts result in vast amounts of data for King County Lakes that otherwise wouldn’t be collected. We are always looking for new volunteers to serve as monitors and back-up monitors. If you are interested, please contact us! Contact information can be found at the bottom of the page.
View your lake's water quality data on the small lakes data and info page.
And for lakes with continuous data loggers you can access lake level and water temperature data on the Hydrologic Information Center.
