Summary
This dataset is a geographic information systems shapefile containing basin polygons, site information, basin characteristics, results of flood-frequency analysis, and results of Bayesian weighted least-squares / Bayesian generalized least-squares (B-WLS/B-GLS) analysis for 183 streamflow gaging stations (streamgages) operated by the U.S. Geological Survey (USGS) in parts of hydrologic unit 02 (mid-Atlantic region) in eastern New York and Pennsylvania and the surrounding states of Connecticut, Maryland, Massachusetts, New Jersey, Vermont, Virginia, West Virginia that were used to estimate regional skewness of annual peak flows.

Summary
This dataset is a geographic information systems shapefile containing basin polygons, site information, basin characteristics, results of flood-frequency analysis, and results of Bayesian weighted least-squares / Bayesian generalized least-squares (B-WLS/B-GLS) analysis for 183 streamflow gaging stations (streamgages) operated by the U.S. Geological Survey (USGS) in parts of hydrologic unit 02 (mid-Atlantic region) in eastern New York and Pennsylvania and the surrounding states of Connecticut, Maryland, Massachusetts, New Jersey, Vermont, Virginia, West Virginia that were used to estimate regional skewness of annual peak flows. Bayesian weighted least-squares / Bayesian generalized Least-Squares (B-WLS/B-GLS) regression was used to relate flood skew computed for each streamgage to a suite of ten explanatory variables (basin characteristics), including: latitude and longitude of the basin centroids; drainage area, mean basin slope, mean basin elevation, basin compactness; mean annual precipitation, mean basin soil permeability, percentage of the basin in forested land-cover; and percentage of the basin in open water. For 156 of the 183 streamgages, basin polygons and characteristics were obtained from the GAGES II database (Falcone, 2011). For the remaining 27 streamgages-22 in New York, 2 in Pennsylvania, one in Connecticut, one in Maryland, and one in New Jersey-basin polygons were obtained from StreamStats (Ries and others, 2017) and the basin characteristics were computed using datasets and methods used in the development of GAGES II. The USGS station identification number, name, state, latitude and longitude, and 8-digit hydrologic unit code for each streamgage were obtained from the USGS National Water Information System (U.S. Geological Survey, 2020). Also included as attributes of each polygon are: Information from Tables 1 (Input Data Summary), 2 (Results of Multiple Grubbs-Beck and Mann-Kendall tests), and 3 (Moments and mean squared error from log-Pearson III analysis) in the PeakFQ output (.PRT) file for the corresponding streamgage; pseudo record length (PRL) and unbiased skew for each streamgage, derived from results of flood-frequency analysis and used in the B-WLS/B-GLS regression analysis; and the residual for each streamgage from the B-WLS/B-GLS analysis.

Information in the files provided in this data release were used to estimate regional regional flood skew for parts of the mid-Atlantic region (hydrologic unit 02) using annual peak-flow data from 183 USGS streamgages in parts of eastern New York and Pennsylvania and the surrounding states of Connecticut, Maryland, Massachusetts, New Jersey, Vermont, Virginia, and West Virginia. The data are provided as a public service such that results of the study can be reproduced.
