The main constituents of the stream are stormwater runoff, groundwater, and precipitation. The stream is fed by several small tributaries, including Dorsey Run and Triadelphia Reservoir. The flow varies seasonally, with higher flows in the spring due to snowmelt and rain, and lower flows in the summer and fall. There are no dams on the stream. One quirky fact about the hydrology of Cattail Creek is that it is known for its population of crayfish, which are an important indicator of water quality.
