These are two USGS Western Fisheries Research Center scientists, Carl Ostberg and Jeff Duda (from left to right), sitting on a fallen tree in Skagit, WA. These scientists study critical fish, like salmon, in the Ross Dam reservoir and tributaries.

This is a photo of a fish in Ross Lake, WA called the Redside Shiner. Ecologists at the Western Fisheries Research Center are studying this fish and the food web in Ross Lake.

This is a photo of Ross Dam as viewed from the boat. This photo was taken by fisheries scientists from the USGS Western Fisheries Research Center.

This is a photo of scientist, Marshal Hoy, holding a bull trout in Ross Lake. The USGS Western Fisheries Research Center does food web studies in Ross Lake to better understand the ecology and habitat for salmon in the area.
