GLACIER NATIONAL PARK (AP) — Officials plan to poison off fish to help other fish species repopulate two lakes and a creek in Glacier National Park.
The project in the upper reaches of Camas Creek will attempt to keep native westslope cutthroat trout from breeding with nonnative Yellowstone cutthroat trout.
Park and state wildlife officials plan to use the poison rotenone to remove the nonnative Yellowstone cutthroat from Lake Evangeline, Camas Lake and Camas Creek. They will then restock the lakes and creek with westslope cutthroat and bull trout.
The Daily Inter Lake reports the genetically pure fish will come from the Sekokini Springs Native Fish Hatchery in Coram and the Creston National Fish Hatchery in Kalispell.
The area will be closed to the public through next spring.
