Total streamflow across the Susquehanna River was last observed at 136,615 cfs, and is expected to yield approximately 270,973 acre-ft of water today; about 58% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 234,451 cfs, with recent peaks last observed on 2011-09-09 when daily discharge volume was observed at 3,832,200 cfs.

Maximum discharge along the river is currently at the Susquehanna River At Harrisburg reporting a streamflow rate of 16,300 cfs. However, the streamgauge with the highest stage along the river is the Susquehanna River At Marietta with a gauge stage of 34.17 ft. This river is monitored from 16 different streamgauging stations along the Susquehanna River, the highest being situated at an altitude of 979 ft, the Susquehanna River At Unadilla Ny.

The Susquehanna River, located in the northeastern United States, stretches for 444 miles from its source in upstate New York to the Chesapeake Bay. It has played a significant role in the history of the region, serving as a transportation route for Native Americans and early settlers. The river's hydrology is characterized by high flow variability, with floods and droughts being common. The river is home to several reservoirs and dams, including the Conowingo Dam and the Safe Harbor Dam, both of which generate hydroelectric power. Recreational activities such as fishing, boating, and camping are popular along the river, and it also supports agriculture by providing irrigation for crops. However, pollution from agricultural runoff and other sources has impacted the river's water quality and ecosystem.
