The Mohawk River between New York State Barge Canal Locks 7 and 8 near Schenectady, NY is susceptible to ice jams during periods of river-ice break-up. Ice jams in this reach typically form at channel constrictions, bridge piers, lock and dam structures, and sections with a reduced floodplain (Foster and others, 2011). Ice jam related flooding can result from backwater associated with the jam or from water released downstream when a jam fails. Schenectady is particularly vulnerable to ice jam related flooding; Lederer and Garver (2001) estimated that 80% of historic Mohawk River floods in Schenectady have been associated with winter snowmelt and associated ice floes.
In cooperation with the New York State Department of Environmental Conservation's Mohawk River Basin Program, the New York State Power Authority, Brookfield Renewable Power, and Union College, USGS is monitoring river elevation at two streamgages between Locks 7 and 8. A web camera installed at a third location, between the gages, in the Stockade District of Schenectady, provides real-time images of the river during winter months.
