Summary

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) [...]

Purpose

These data were developed as part of the Regional Drought Early Warning System Project (RDEWS) and National Drought Characterization and Prediction Project which are part of the USGS Water Mission Area (WMA) National Drought Prediction Project. This effort was undertaken to support statistical analysis, map display, and model parameterization and to help advance understanding and prediction of hydrological drought across the Continental United States.

Provenance

In January of 2022, the 4 Streamflow_percentiles_xxxxxxxxx_xxxx.zip were updated to correct a minor formatting issue that impacted the streamflow percentile files for 16/3198 streamgages in the study. One of the columns is the station ID called StaID. This is the 8-digit USGS identifier for the gage in character format. The readR read_csv function read the 8-digit ID as a viable date format so for those 16 sites instead of being an 8-character string (e.g. "01350120") it was converted to a date format (e.g. "0135-01-20"). Since it impacted only a small fraction of the sites (<1%) it wasn't captured in the spot checks we did, and since it was only a descriptive column it wasn't captured when testing the plotting of the data. All of these cases were identified for each of the 4 zip files and the formatting was corrected. This impacts 16 sites for the 1981-2020 period, 2 sites for the 1951-2020 period, and 1 site for the 1921-2020 period and the CRB regional period. The streamgage IDs that were impacted were: "01350120", "01480617", "01671020", "02130910", "02160105", "02471001", "03011020", "04100222", "04240120", "05570910", "07060710", "07191220", "07301110", "08110325", "08110430", and "09371010".
