The main constituents of the flow are precipitation and snowmelt. The river is fed by several tributaries, including the Juniata River and the Conestoga River, and is impounded by several dams, including the Safe Harbor Dam and the Conowingo Dam. In the summer months, the river flow tends to decrease due to lower precipitation levels, while in the winter and spring, flow increases due to snowmelt and rain. A unique aspect of the Susquehanna River is that it is the longest river on the East Coast without commercial barge traffic.
