The river has several tributaries, including the Shade Creek and Paint Creek, and is impounded by the Quemahoning Dam. Seasonal trends in flow are influenced by precipitation patterns, with high flows typically occurring in the spring and low flows in the summer. Interestingly, the Stonycreek River was the site of the 1977 Johnstown Flood, which resulted in significant damage and loss of life. Monitoring the flow of the river can help inform flood forecasting and management strategies.
