The river is fed by several tributaries, including the Monocacy River, and is also regulated by the upstream dam at Little Falls. Seasonally, the river experiences high flows in the spring due to snowmelt and frequent rainfall, while lower flows are typical in the late summer and fall. Interestingly, the Point of Rocks area was a popular stop for canal boats traveling along the C&O Canal in the 1800s. Today, the Potomac River serves as a popular recreational destination for fishing, boating, and other outdoor activities.
