Lake Sammamish Volunteer Monitoring Program

Program Summary

Volunteers have been collecting physical data along the Lake Sammamish shoreline since 1999. These data augment data currently collected at seven sites on Lake Sammamish by the County through the Major Lakes Ambient Monitoring Program. Parameters monitored by volunteers include lake level, precipitation, secchi disk measurements, and water temperature. The volunteers monitor secchi depth and temperature from their docks.

Volunteers also collect lake use information including the presence of boats, swimmers, birds, wildlife, and algae. They also alert King County staff when unusual water quality issues are present. Monitoring data are submitted on a quarterly basis. There are no significant data gaps since beginning the program in 1999. Below are links to summaries of data collected by volunteers, organized by water year. The program currently includes three active volunteer monitors, down from the original 11 in 1999. We would love to have additional volunteers!

Site locations

Volunteers monitor the lake from their property on the lake shoreline. Each site location is assigned a site number. See the table below for information about past and current sites.
