Winter-spring nitrogen loads as measured at the Susquehanna River at Conowingo Maryland and Potomac River at Washington, D.C. have been determined to be an effective indicator of summer anoxic and hypoxic volume in Chesapeake Bay. The U.S. Geological Survey (USGS) provides an estimate of winter-spring nitrogen loadings to support an annual forecast of summer Chesapeake Bay conditions. The specific period of estimation includes the months of January through May. This forecast is coordinated through an established relationship with the National Oceanic and Atmospheric Administration (NOAA), University of Maryland Center for Estuarine Science (UMCES) and Maryland's Department of Natural Resources. The results presented...

Data release includes the U.S. Geological Survey (USGS) estimate of spring nitrogen fluxes summed from nine tributaries to the Chesapeake Bay from 1985 to 2021. Data are presented as the sum from tributaries within the USGS River Input Monitoring (RIM) network identified by site numbers: 01491000, 01578310, 01594440, 01646580, 01668000, 01673000, 01674500, 02035000, 02041650. Periods of estimation include January through May and November through May. The estimates are made using up-to-date streamflow and all total nitrogen analyses available as of June 1 of the reporting year.
