A new Surface Water Toolbox was developed by the U.S. Geological Survey and the U.S. Environmental Protection Agency. The Surface Water Toolbox is a user friendly, downloadable tool for water managers to estimate a wide variety of streamflow statistics. This tool can be downloaded from https://water.usgs.gov/osw/swtoolbox/ and enables users to:
• Estimate critical flow statistics such as 7Q10 for gaged and un-gaged streams;
• Use a variety of statistic tests to evaluate emerging trends and identify anomalies.
