Maple Creek is a river flowing through the semi-arid southwest region of Saskatchewan, Canada, in the area historically known as Palliser's Triangle. Originating in the Cypress Hills, the creek flows generally northward before emptying into the endorheic Bigstick Lake. The surrounding landscape is characterized by sandy soils that limit intensive agriculture, making cattle grazing the dominant land use. The town of Maple Creek is the only notable community along the river's course. Due to the dry and drought-prone nature of the region, reservoirs have been constructed along the river and throughout its watershed to maintain a stable water supply for irrigation purposes, which influences flow conditions throughout the year.
