Marian Lake is a remarkable and productive fishery located in the Tłı̨chǫ (Tlicho) region of the Northwest Territories, Canada, situated near the community of Behchokǫ̀. Stretching approximately 35 kilometers in length and ranging from 3 to 10 kilometers in width, this expansive lake is characterized by its notably shallow nature, with depths generally ranging from just 1 to 2 meters across most of its basin. The lake is dotted with numerous islands and supports dense aquatic vegetation during the summer months, creating a mesotrophic environment that is highly productive for fish during the warmer season. Its shallow character means that in winter, the lake freezes to the bottom in most areas, making it primarily a warm-season fishery. Marian Lake functions as both a summer feeding ground and a critical migratory corridor, with fish moving through the lake toward the Marian River for fall spawning runs.
