The river is primarily fed by snowmelt and rainfall, with potential tributaries including the Sauk, Pilchuck, and Boulder Rivers. The presence of the Whitehorse Dam can affect the river's flow, but it is not considered a major source of water. Seasonal trends show the highest flows in the winter and early spring, with low flows in the summer and fall. Interestingly, the Stillaguamish River is home to several species of salmon, including Chinook and coho, that spawn in the tributaries.
