The U.S. Fish and Wildlife Service Colorado River Fish project (CRFP) is working hard to restore native fish populations in the Colorado River and other western rivers and lakes in Grand Junction, Colorado.

GRAND JUNCTION, CO - AUGUST 16: USFW Biological technician and CRFP crew leader Britney McKelvey looks at the Redlands Water and Power Dam on the Gunnison River on August 16, 2016 in Grand Junction, Colorado. The damn, which was built in 1918, is as long as a football field and 8 1/2 feet high. For 78 years the damn had kept endangered fish from being able to spawn naturally upstream, because they couldn't get past the damn. This caused a large decline in fish populations below the damn The USFW service built a fish ladder in 1996 that has helped to revive the populations of Colorado's native fish such as this Pike Minnow, Bonytail, Humpback Chub and the Razorback Sucker. The fish ladder has also helped officials with the US Fish and Wildlife Service Colorado River Fish Project (CRFP) to be able to take out non-native fish that are leading to the decline in native fish as well.
