The Susquehanna mainstem covers 444 river miles
over diverse physiography ranging from Glaciated
Appalachian High Plateau at Otsego Lake near
Cooperstown, NY to Piedmont Uplands at its input
to the Chesapeake Bay at Havre de Grace, MD. The
river drains an area of 27,500 square miles over
a range of elevation from 0 meters to 930 meters
(asl). The river contributes 90 of the fresh
water inputs to the upper bay and 50 to the
entire bay. Basin climate is largely
characterized as humid continental and
experiences hydrologic extremes typical for the
eastern US such as flooding, drought, and
seasonal hurricanes. These characteristics are
amplified by large-scale landscape modifications
in the basin, influenced by intense human impacts
through rapid urbanization, mining, agriculture,
forestry, land use change and others.
