The main constituents of the flow include precipitation, snowmelt, and runoff from the surrounding area. There are several tributaries that feed into the Oswego River, including the Oneida River and Salmon River. The flow rate of the river is known to vary seasonally, with the highest flows typically occurring in the spring due to snowmelt and the lowest flows occurring in the late summer and fall months. The Lock 7 hydroelectric dam is located on this stretch of the river, which can impact the flow rate. An interesting fact about the Oswego River is that it was once a major transportation route for goods in the 1800s, with boats traveling from Lake Ontario to the Erie Canal.
