Two drainages in the High Uintas are scheduled for treatments as part of the ongoing effort to restore native Colorado River cutthroat trout. Rotenone treatments have been conducted the past several years on different waterbodies on the north and south slopes of the Uintas. Rotenone is a natural substance that is a respiratory toxin to fish but is not dangerous to people, pets or other wildlife in the amount used to treat streams and lakes The.public will be required to stay out of the area during the treatments. This year, biologists will be conducting treatments in the following areas in the High Uintas: Oweep Creek drainage on the south slope from July 31st to August 4th; South Fork Sheep Creek on the north slope from August 28th through the 30th; Daggett, Penguin, Upper Anson and Lower Anson lakes on the north slope from August 28th through the 29th; and Porcupine Lake on the south slope from July 31st to August 4th. The DWR will announce ahead of time an emergency change for all lakes in the South Fork Sheep Creek drainage so that anglers can harvest more fish prior to the treatments.
