Data and equations used to reconstruct historical daily streamflows in northern New Jersey and southeastern New York, water years 1922-2010

This U.S. Geological Survey (USGS) data release provides daily reconstructed streamflows at 53 sites in selected subbasins in northern New Jersey and southeastern New York for water years 1922-2010; data and equations used to determine the reconstructed flows are included. These subbasins contain one or more surface-water diversions that are currently operated or have been operated in the past by water purveyors or the New Jersey Department of Environmental Protection (NJDEP). The streams include the Passaic and Hackensack Rivers and some adjacent streams. Reconstructed streamflows are estimates of those streamflows that would have occurred without the effects of changes in reservoir storage or surface-water diversions by water purveyors. The reconstructed streamflows are not intended to fully represent natural conditions because surficial aquifer withdrawals and effluent return flows were not included. These data support the following publication: Hickman, R.E., and McHugh, A.R., 2018, Methods used to reconstruct historical daily streamflows in northern New Jersey and southeastern New York, water years 1922-2010: U.S. Geological Survey Scientific Investigations Report 2018-5068, 75 p., https://doi.org/10.3133/sir20185068.
