This summer, ODFW will be applying rotenone to Mann Lake in the Steens Mountain area. The high desert lake has been stocked with Lahontan Cutthroat trout since the 1950s, but an explosion of introduced goldfish has wrecked the fishery.

Prior to the rotenone treatment, ODFW is looking for anglers to help catch Lahontan Cutthroat. They will be held in a nearby pond and placed back into Mann Lake once re-stocking begins. For more info, check the ODFW press release.
Lahontan cutthroat trout are native to the high desert of Eastern Oregon. Check out this video on ODFW doing a Lahontan Cutthroat population study.
