Sekellick, A.J., Ator, S.W., Brakebill, J.W., and Blomquist, J.D., 2021, SPARROW model input datasets and predictions of nitrogen loads in streams of the Chesapeake Bay watershed: U.S. Geological Survey data release, https://doi.org/10.5066/P9FLXZFG.
Summary
This data release contains mean-annual total nitrogen (TN) loads predicted by a SPARROW model for individual stream and shoreline reaches in the Chesapeake watershed as defined by NHDPlus, a 1:100,000 scale representation of stream hydrography built upon the National Hydrography Dataset (NHD) (Horizon Systems, 2010). Also included are the input variables required to execute the model, including landscape characteristics, nutrient inputs to land, and calibration data from water quality monitoring stations. Further details on model construction and results are described in Ator (2011, https://doi.org/10.3133/sir20115167).

This data release is intended to support modeling and data analysis. Data are provided at the NHDPlus version 1 catchment scale and can be linked to spatial datasets using the COMID attribute. Confidence intervals for predictions are also included.
