Lake At Voyageurs National Park Studied For Muskie Population

Beavers are incredible dam builders. And those dams can affect other species in "the neighborhood." They can increase the size of a lake or, if they fail, quickly drain a lake. At Voyageurs National Park, biologists want to know how the failure in 2001 of a beaver dam at the outlet of Shoepack Lake impacted the resident population of muskellunge, better known to most as "muskies."
