The lake has been the target of two efforts to eradicate invasive species and re-introduce native flora and fish.
[1] Several small streams flow into the lake, and the outflow from it eventually drains into the Swanson River.
[6] In 2012 the lake was closed to the public and the Alaska Department of Fish and Game introduced rotenone, a piscicide, to eliminate highly aggressive northern pike that had apparently been illegally introduced to the lake and were decimating the native fish population.
A drip station dispensing potassium, which neutralizes rotenone, was installed at the lake's outlet to prevent contaminating other water bodies downstream.
[6][9] A multiagency task force was created to deal with this issue and monitor lake conditions.
