The river's flow is largely controlled by the West Thompson Dam, which regulates water levels for flood control and recreation. Seasonal trends show higher flows in the spring due to snowmelt, and lower flows in the summer and fall. Interesting facts about the hydrology of the river include its designation as a National Wild and Scenic River, and its historical use as a source of power for mills and factories.
