Chesapeake Bay Period-of-Record Annual Mean Streamflow By Cross Section: Susquehanna River and Potomac River

This table contains historic Chesapeake Bay annual mean streamflow values for the Susquehanna River and the Potomac River calculated using documented methods. Annual mean streamflow values for the Susquehanna and Potomac Rivers are calculated directly from USGS gaging-station data. Sections A and B provide cumulative streamflow values for flow entering the bay at each of these defined cross sections (see Bue, 1968). Section B-C provides incremental streamflow values for flow entering the bay between two defined cross sections.
