Buffalo Lake is a remote freshwater lake nestled in the Dehcho region of the southeastern Northwest Territories, Canada, situated adjacent to the western boundary of Wood Buffalo National Park at approximately 60°13′N, 115°30′W. The lake forms the centerpiece of the Ejié Túé Ndáde candidate protected area — known in English as Buffalo Lake, River and Trails — a roughly 2,180 km² landscape encompassing the western portion of the lake, the Buffalo River, and extensive wetland complexes. This is classic boreal wilderness: flat terrain punctuated by peat plateaus, fens, marshes, and mixed coniferous forests of black spruce, white spruce, and jack pine, all within the Taiga Plains ecozone. The Buffalo River drains the lake eastward, emptying into Great Slave Lake approximately 40 km east of Hay River, connecting Buffalo Lake to one of Canada's most productive fisheries. The river drains a watershed of approximately 17,638 km², and its generally swift, shallow character — with maximum depths reaching around 2.0 m in the main channel during spring runoff — reflects the low-relief terrain of the surrounding landscape.
