The river is fed by several smaller streams and tributaries and it is a part of the larger Patuxent River watershed. There are no major dams or reservoirs along the Hawlings River. Seasonal trends show that the river's flow is typically highest in the spring due to snowmelt and precipitation, and lowest in late summer and early fall. Interestingly, the Hawlings River was once known for its abundant populations of American eels, which travel up the river from the ocean to spawn in freshwater.
