Draft Environmental Assessment of the Rotenone Treatment of Ostle Reservoir for the Removal of an Expanding White Sucker Population and Restocking with Rainbow Trout
Species Removal & Relocation - 06/25/2013

Montana Fish, Wildlife & Parks proposes the use of piscicides (rotenone) to eliminate white suckers from Ostle Reservoir. After white suckers are successfully removed, rainbow trout would be stocked into the reservoir. Ostle Reservoir is located in Teton County on the Rocky Mountain Front in the Teton River drainage approximately 26 miles northwest of Choteau, Montana at T26N,R8W,S34. The dam is located at approximately 47.97101°N, -112.63146°W. It is an irrigation reservoir that receives surface runoff and inflow from Rinker Creek and an unnamed ditch conveying water from the Blackleaf Fen and Muddy Creek. The reservoir is located entirely on the Blackleaf Wildlife Management Area (WMA), public land owned and administered by Montana Fish, Wildlife & Parks. The purpose of the project is removal of an expanding white sucker population and restocking with rainbow trout to improve the quality of Ostle Reservoir’s fishery.
