A list of stream gages within the conterminous United States that will serve as the initial list of sites (version 1.0) used for streamflow benchmarking of hydrologic models. Sites within this list were chosen based on their presence in the GAGES-II dataset, their availability of modeled streamflow data from the most recent version of the National Hydrologic Model application of Precipitation-Runoff Modeling System v1.0, and their availability of modeled streamflow data from the most recent version of the NOAA National Water Model application of WRF-hydro version 2.1 retrospective dataset.

This data release contains daily time series estimates of natural streamflow at the outlets of more than 80,000 12-digit hydrologic units in 19 study regions across the conterminous U.S. from October 1, 1980 through September 30, 2017, using three statistical techniques: Nearest-Neighbor Drainage Area Ratio (NNDAR), Map-Correlation Drainage Area Ratio (MCDAR), and Ordinary Kriging of the logarithms of discharge per unit area (OKDAR). Location information and drainage areas for index gages were obtained from the "Reference" gages of the GAGES-II dataset (Falcone, 2011, https://water.usgs.gov/lookup/getspatial?gagesII_Sept2011); location information and drainage areas for the HUC12 outlets were derived from attributes...

This dataset contains the observed and simulated streamflow used to produce the results of the journal article entitled “Bias correction of Retrospective Simulation of Daily Streamflow at Ungauged Locations Using Independently Estimated Flow-Duration Curves ”. Observed streamflow, retrieved from the U.S. Geological Survey’s National Water Information System (https://waterdata.usgs.gov/nwis) in Spring of 2017, is included in comma-separated-values files (CSVs) as cubic feet per second. These CSVs also contain computed nonexceedance probabilities and streamflows estimated with pooled, ordinary kriging, with and without bias correction. CSVs of streamflow duration curves (fdc) are also provided. A streamflow and fdc...
