Estimated daily mean streamflows for HUC12 pour points in the southeastern United States, 1950 - 2009

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2020-08-21T00:00:00Z
This data release contains estimated daily streamflow values for 9,203 level-12 hydrologic unit codes (HUC12) in the southeastern United States for the period 1950-2009. The files are provided in text different format, which can be used in R (https://www.r-project.org/) and in other programs. The 'Site Info' files contain the streamgage information and the 'Daily Values' files contain the predicted daily streamflow value for a given HUC12. Each of the datasets contains 500, 501, or 704 HUC12s, respectively. Data preparation and analysis of the predicted streamflow values were scripted in RStudio (version 3.5.3). Results of the analysis will be used to quantify streamflow alterations across the study area and will be published in a separate product.
