News from the Refuge

Centennial Valley's Red Rock Lakes National Wildlife Refuge is currently working on a sage grouse project; aerial monitoring 49 female grouse radio tagged in April 2014. Refuge biologists are also involved in monitoring radios of 112 imperiled Arctic grayling, a unique member of the salmon family. The grayling were radio marked in the past two years in Upper Red Rock Lake and Red Rock Creek. The current project will determine how they survive in a lake only 5 feet deep. In winter nearly zero oxygen conditions can occur when the snow cover on lake ice is heavy.
