Fish

Trout banner

Game fish inhabit the waters of the refuge. Only two are known to be native, the Arctic Grayling and the Mountain Whitefish.  The numerous lakes, ponds and streams host several species of fish from lake dwellers to stream dwellers and those that go between the streams and the lakes or ponds. 

  • Mountain Whitefish

    Native Arctic grayling are distinguished by a large dorsal fin, larger scales than trout and a forked tail. It spawns in the early spring. Historically, spawning runs of many thousands were seen in most streams of this area. Now, only a remnant population is found, mainly in Red Rock Creek. Aquatic insects and crustaceans form the bulk of the grayling’s diet. In 2010 the Arctic grayling population in the Centennial Valley were listed as a Candidate Species under the Threatened and Endangered Species Act. All grayling caught must be released immediately. See Grayling Restoration Project at the refuge.
