The Susquehanna River is the source of the streamflow, which is influenced by various tributaries and dams. The Conestoga River, Pequea Creek, and Muddy Creek are some of the tributaries that contribute to the flow. The Holtwood, Safe Harbor, and Conowingo Dams also affect the flow. The river experiences seasonal trends, with the highest flows occurring in the spring due to snowmelt and precipitation. In the summer, flows tend to be lower due to less precipitation. One interesting fact about the hydrology of the Susquehanna River is that it is one of the oldest rivers in the world, estimated to be over 300 million years old.
