The flow of the river is influenced by several factors, including precipitation, snowmelt, and irrigation diversion. The river is fed by several tributaries, including the Ashnola River and the Pasayten River. There are no major dams on the Similkameen River, but there are several small irrigation diversions that can affect the flow of the river. The river has a seasonal flow, with high water levels in the spring and low water levels in the summer and fall. Interestingly, the Similkameen River is one of the few rivers in the United States that flows north.
