The river is fed by several tributaries, including the Tilton River and Cispus River. Seasonally, the highest flows occur in the spring months due to snowmelt, with lower flows in the summer and fall. Interestingly, the Cowlitz River is known for its steelhead and salmon fisheries and supports a significant portion of the state's anadromous fish populations. The river also serves as a source of hydroelectric power, with several dams along its length.
