This is an image of Glen Canyon, located in Arizona. Glen Canyon is a natural canyon carved by the Colorado River and located largely in Utah. A small part of the lower end of Glen Canyon extends into northern Arizona and ends at Lee's Ferry, near Glen Canyon Dam.

The image above is a photograph of the Glen Canyon Dam (GCD) in Arizona. Recent captures of non-native fishes in the Colorado River downstream of GCD indicate a potential threat to imperiled native fish in the Grand Canyon.

WFRC scientist Lisa Wetzel uses a fluorescing stereoscope to look for microplastics in samples of Smallmouth Bass tissue provided by the Nez Perce Tribe, Idaho.

Juvenile Coho salmon (Oncorhynchus kisutch) behavior is assessed following exposure to 6PPD-quinone, a derivative of the compound 6PPD which is used in tires to prevent wear.

This is a drone photo of the bio-acoustic fish fence in the Georgiana Slough, a tributary of the Sacramento River Delta. It is used to guide fish safely out to the ocean.

Our scientists are collaborating with the fisheries staff from the Spokane Tribe and Coeur d'Alene Tribe in a study to determine how susceptible Redband trout are to IHN virus (infectious hematopoietic necrosis virus).

Two groups of sea lions can be seen some distance away from the shore in deeper water. Sea lions are herring predators, feeding on herring while they spawn. Therefore, the presence of sea lions can be indicative of the presence of herring. However, herring schools are absent in this image.
