Streamflow data and basin characteristics of natural streams in central and western Colorado, 2019

The U.S. Geological Survey (USGS), in cooperation with the Colorado Department of Transportation, developed peak-, mean-, and low-streamflow regional-regression equations for natural streamflow in central and western Colorado. A total of 418 streamgages were selected for the study having a minimum of 10 years of unregulated streamflows. This data release presents hydrologic data through 2019 and geographic information systems data that were compiled, processed, and analyzed for this peak-, mean-, and low-streamflow study. The parent page of this data release includes the text file StreamgageInfoValues.txt, which is the final dataset used to develop the regression equations and includes streamflow variables and 13 topographic and climatic attributes for the 418 streamgages. Five child pages in this data release (7-day minimum and maximum, Mean-streamflow data, Peak-streamflow data, R scripts, Streamflow-duration values) present data for and methods used to develop the streamflow variables used in the regressions including mean-monthly and 7-day minimum and maximum streamflows, annual exceedance-probability streamflows, and flow duration values. The child page 'Basin characteristics rasters' includes the raster datasets used to develop topographic and climatic attributes for the 418 streamgage basins.
