The Institute began its Northwest Lake Monitoring program in 2006 as a public service to provide baseline water quality data for local lakes that did not have ongoing water quality monitoring programs. The lakes listed below have been sampled from the shoreline at public access points. We collect samples during spring and late summer. Lake names and elevations conform to the USGS Geographic Names Information System.
Before downloading the data, please also download the Northwest Lakes README file. Metadata about the lakes, including coordinates, surface areas, and elevations, can be downloaded here.
