There are two dams along the river, Merwin and Yale, which provide hydroelectric power. The flow of the river is highest in the spring and lowest in the fall, with an average annual flow of 2,000 cubic feet per second. One interesting fact about the hydrology of the Lewis River is that it is home to several fish species, including steelhead, coho, and chinook salmon, that migrate from the Pacific Ocean to spawn in the river's tributaries.
