Watersheds Canada lesson 3 – At-Capacity Cold Water Lakes factsheet

Lake Trout Fact Sheet

The document discusses the unique native strain of lake trout in the Bancroft Area, which is sensitive to aquatic ecosystem health. Lake trout lakes are considered ‘at capacity’ for shoreline development if measured oxygen is below or predicted to fall below the dissolved oxygen criterion. The minimum dissolved oxygen concentration necessary to sustain a lake trout population is 7 mg/L. Shoreline developments can have detrimental effects on water quality and habitat.
