Streamflow Drought Metrics for Select United States Geological Survey Streamgages for Three Different Time Periods from 1921 - 2020

This metadata record describes a series of datasets containing metrics used to characterize drought for four sets of United States Geological Survey (USGS) streamgages in the conterminous United States (CONUS) for three different time periods between 1921 and 2020 outlined below. The streamgages used are a subset based on the criteria used in Geospatial Attributes of Gages for Evaluating Streamflow, version II (GAGESII, Falcone, 2011). Time periods use climate years, April 1 through March 31. These metrics include streamflow percentiles, identified drought events, annual low streamflow drought statistics, and various attributes for each of those events. These data are arranged here by study group with the following child items: 1) Select CONUS-wide GAGES-II streamflow drought metrics for the period 1921-2020. 2) Select CONUS-wide GAGES-II streamflow drought metrics for the period 1951-2020. 3) Select CONUS-wide GAGES-II streamflow drought metrics for the period 1980-2020. 4) Select Colorado River basin GAGES-II streamflow drought metrics for the period 1980-2020.
