Rare grayling get a new home

About 400 arctic grayling and nearly 300 native cutthroat trout have a new home in Handkerchief Lake. The lake sits about four miles above the Hungry Horse Reservoir. In the fall of 2016 the lake was treated with the fish poison Rotenone to kill off the non-native rainbow-cutthroat trout hybrids in the lake, as part of a large project by Montana Fish, Wildlife and Parks to preserve the genetic integrity of the South Fork of the Flathead’s native westslope cutthroat trout.
