The lake lies within the Boissevain Till Plain and is underlain by Cretaceous Shales of the Riding Mountain Formation. A Late Cretaceous-Tertiary outlier of Boissevain Formation sandstone overlain by sanstones and shales of the Turtle Mountain Formation occurs on Turtle Mountain immediately south of the lake. The origin of the basin is due to a collapse feature caused by the solution of salt from Devonian evaporite deposits and/or to a Pre-Jurassic erosion feature on the Mississippian escarpment underlying the basin.
