Summit Lake[1] is a lake in the east-central part of the Canadian province of Saskatchewan in Narrow Hills Provincial Park.[2] It is situated in a glacier-formed valley in the Cub Hills[3] and the boreal forest[4] ecozone of Canada. It is located north of Lost Echo Lake and is accessed from Highway 913. There are no communities or settlements on the lake.[5]
Several small rivers flow into Summit Lake from the surrounding hills and muskeg. Its outflow is at the western end and, via a short river, it flows into Caribou Creek, which flows south through the lakes of Lost Echo, Lower Echo, Upper Fishing, and Lower Fishing and is a tributary of the south flowing Stewart Creek. Stewart Creek flows into the east flowing Torch River, which is a tributary of the Saskatchewan River and part of the Hudson Bay drainage basin.[6]
Fish commonly found in Summit Lake include lake trout, northern pike, walleye, and yellow perch.[7] [8] The lake was last stocked with 100,000 walleye fry in 2019.[9]
