This stream receives its flow from several smaller tributaries, including Piscataway Creek and Mattaponi Creek. There are several dams along the Western Branch that affect its flow rate, including the Upper Marlboro Dam and the Lower Marlboro Dam. Seasonal trends in flow are influenced by precipitation, with higher flows occurring in the spring and lower flows in the summer and fall. One interesting fact about this stream is that it provides habitat for several species of fish, including American shad, hickory shad, and river herring.
