Catching Colorado River Cutthroat Trout Near Trapper's Lake

September 17, 2015

This summer CNHP zoologist John
Sovell conducted surveys for wildlife species across Garfield County, Colorado. In July, Sovell’s surveys included fishing for Colorado River cutthroat trout. His field work is part of a larger effort led by Delia Malone (CNHP ecologist) to document locations of rare plant and animal species in the county, as well as noxious weed locations. Sovell and Malone will provide information from their county-wide biological surveys to Garfield County to aid in planning and natural resource management.

Colorado River cutthroat trout are one of dozens of rare species that occur in Garfield County, including Colorado hookless cactus and Debeque phacelia. Both of these rare plants are listed as Threatened under the Endangered Species Act.

A downed log rests in a pool occupied by Colorado River cutthroat trout on the North Fork of the White River near Trapper’s Lake. Colorado River cutthroat trout rely on large woody debris like this tree to help form pools, store spawning gravels, and provide refuge from predators. 

Sovell updated information on Colorado River cutthroat trout at four locations in Garfield County, including the North Fork of the White River where it empties into Trapper’s Lake. These brilliantly colored fish are one of three extant subspecies of trout native to Colorado. Recent genetic and morphological studies suggest that there are two extant lineages of cutthroat trout on Colorado’s Western Slope. Cutthroat trout in the White River Basin are part of what is known as the Blue Lineage. For more information on Colorado River cutthroat trout, check out the newly updated State Wildlife Action Plan.

John Sovell, CNHP zoologist, catches a Colorado River cutthroat trout as part of  the 2015 Garfield County Survey of Critical Biological Resources.
