The river is regulated by the Detroit Dam, which can impact flow rates, particularly in the summer months. Seasonally, the river experiences high flows in the winter and lower flows in the summer. Some interesting facts about the hydrology of the North Santiam River include its importance for salmon and steelhead spawning and the presence of a unique species of freshwater mussel, the Oregon floater, which is found only in this river system.
