This river is fed by various tributaries, including Kettle Creek and Mosquito Creek. Additionally, several dams along the river regulate its flow, including the Karthaus and Curwensville Dams. Seasonally, the river experiences higher flows in the spring due to snowmelt and rain, while lower flows occur in the summer and fall. Interestingly, the West Branch of the Susquehanna River serves as a major source of drinking water for residents of the nearby town of Lock Haven.
