Lake trout are native to New England, the Great Lakes area, and Canada. In the Lake Michigan waters of Wisconsin, they can be found in the outer half of Green Bay and along the entire Lake Michigan shoreline.
Spawning takes place October though early November, when water temperature falls below 50° F. The females spawn over boulders that have been cleaned off by the males.Spawning takes place over the rock as males press along side of females. A single female may lay 2,000-20,000 eggs depending on her size.
