Clowhom Lake is a reservoir in the Sechelt Inlet basin, located on the Clowhom River at the upper end of Salmon Inlet, the southern side-inlet of Sechelt Inlet. Formed by Clowhom Dam, the reservoir was formerly two lakes, Upper Clowhom Lake and Lower Clowhom Lake, and had been referred to prior to their merger from inundation as the Clowhom Lakes.
