Ross Lake is a large reservoir in the North Cascade mountains of northern Washington state.  This photo was taken while conducting food web research to support the Skagit River Hydroelectric Dam FERC relicensing process. To learn more about this project and other related research you can visit the WFRC Ecology Section website.
