Pike Lake is a shallow oxbow lake of the South Saskatchewan River located approximately 36 kilometres south of downtown Saskatoon in the RM of Vanscoy No. 345, Saskatchewan. Sitting at an elevation of 478 metres (1,568 ft) and positioned just 2.5 kilometres west of the South Saskatchewan River, the lake covers roughly 639 acres with a maximum length of 4 kilometres and a shoreline stretching over 20 kilometres. Its most defining characteristic is its extremely shallow depth — maxing out at just 2.5 metres (about 8 feet) — which makes it a warm, weedy, and productive environment for certain species. The lake lies within the aspen parkland transitional biome, a zone between the open prairie and boreal forest in Palliser's Triangle, and is surrounded by aspen, ash, and birch trees. Pike Lake Provincial Park occupies most of the southern half of the lake and serves as the primary recreational hub in the area, making this the closest recreational lake to Saskatoon and one of the most visited in the region.
