River in Yellowstone to be cleared of exotic fish
A stretch of the Gibbon River and its headwater lakes are being poisoned so Yellowstone National Park can remove non-native fish and reintroduce native west slope cutthroat trout and river-running grayling.
Yellowstone officials say the two species are being reintroduced as part of the effort to help flora and fauna of Yellowstone adapt to the warming climate.
The Jackson Hole News & Guide reports warm water in the height of summer closes down waters to fishing on the 8,000-foot Yellowstone plateau with some regularity.
The project will treat 18 miles of stream and 232 acres of standing water.
