Mamawi Lake sits within the remarkable Peace-Athabasca Delta in northern Alberta, Canada, at approximately 58°38'N, 111°28'W — one of the world's largest freshwater deltas and a UNESCO World Heritage Site within Wood Buffalo National Park. This shallow, expansive lake is intimately connected to the broader Claire-Mamawi lakes system, linked by a network of channels, wetlands, and floodplains that define the ecological character of the entire delta. With a maximum depth of only 1.5 metres, Mamawi is an exceptionally shallow water body, and this physical characteristic shapes nearly every aspect of its ecology, fishery, and seasonal dynamics. The lake functions as critical spawning and feeding habitat within a vast and ecologically significant wetland system, drawing fish species that migrate through the delta's interconnected waterways.

The Claire-Mamawi lakes system is assessed at 10 established monitoring sites, reflecting the broad distribution of fish throughout the interconnected lake and channel network. The channels connecting Mamawi Lake to the broader delta system — including the Chenal des Quatre Fourches and associated waterways — are important movement corridors for goldeye, northern pike, lake whitefish, and walleye, and represent productive fishing areas as fish move between the lake and the larger Peace and Athabasca river systems. The shallow margins and channel mouths where water flows into and out of Mamawi are natural concentration points for fish, particularly during the spring migration of goldeye into the system.
