Description
This project successfully removed illegally introduced invasive northern pike from two lakes at the headwaters of Cottonwood Creek drainage, Kings and Anderson lakes, using rotenone. This treatment occurred in October 2020 just prior to freeze up, and post treatment water sample analysis indicated lethal concentrations of rotenone were obtained throughout the lakes.
Project Benefit
Salmonid populations throughout Cottonwood Creek drainage and in presently uninvaded Knik Arm drainages are tremendously important to the ecology and economy of the region. This project will ensure that the Cottonwood Creek drainage no longer harbors source populations from which northern pike could spread or be illegally or unintentionally introduced elsewhere.
