The river is a source of drinking water for the city of Portland, and its flow is affected by the Bull Run Watershed, which includes several tributaries and dams. The river typically experiences high flows in the winter due to precipitation, and low flows in the summer due to decreased rainfall. Interestingly, the Bull Run Watershed is one of only two municipal watersheds in the U.S. that is protected from logging and other human activities.
