Another round of rotenone treatments to help restore native Colorado River cutthroat trout on drainages in the High Uintas is coming up. This is the 4th consecutive year that the Utah Division of Wildlife Resources has coordinated with Ashley National Forest on the treatments. “Over the past 20 years, we have made significant progress on Colorado River cutthroat trout restoration in northeastern Utah,” shares DWR Northeastern Region Aquatics Manager Natalie Boren. “We are excited to be within seven years of finishing up restoration efforts and reaching our conservation team goals with this species.” This year, biologists will be conducting the treatments in the following areas in the High Uintas: Fall Creek drainage south slope from August 4th through the 7th with the area reopening to the public on August 9th and South Fork Sheep Creek north slope on August 26th. Work on the South Fork Sheep Creek north slope is a retreatment of the lower end of the creek and the area should reopen to the public on August 29th. A series of two to three treatments is the standard protocol for effective cutthroat trout restoration. This will be the first year of treatment for Fall Creek and the third year of treatments for the South Fork of Sheep Creek.
