PeakFQ inputs and selected outputs for Magnitude and Frequency of Peak and Low Flows in the Elkhorn River Basin, Nebraska, 1881-2022
The U.S. Geological Survey (USGS), in cooperation with the Nebraska Department of Transportation, initiated a flow-frequency study for the Elkhorn River basin in Nebraska for flow data for water years 1881-2022. Estimates of the magnitudes of peak were determined using the USGS PeakFQ flood-frequency program, version 7.5.1 at the 1, 2, 5, 10, 20, 25, 40, 50, 100, 200, and 500 year recurrence intervals.
This data release includes peak-flow, specification, output, and export files from version 7.5.1 of USGS PeakFQ software (Veilleux and others, 2014; Flynn and others, 2006) for streamgages in the Elkhorn River Basin in Nebraska. Within PeakFQ software, the Expected Moments Algorithm (EMA) was used to conduct frequency analysis to estimate stream discharges corresponding to the 50, 20, 10, 4, 2, 1, 0.5, and 0.2 percent chance annual exceedance probabilities (otherwise known as the 2-, 5-, 10-, 25-, 50-, 100-, 200-, and 500-year floods, respectively).
