Magnitude and Frequency of Peak and Low Flows in the Elkhorn River Basin, Nebraska, 1881–2022

About this book

This report analyses peak and low streamflows in Nebraska's Elkhorn River Basin using records that extend through 2022. It updates the statistical picture of a basin that experienced major floods in 2010 and 2019 while also examining the behaviour of sustained low-flow periods.

The study describes the streamgage records and analytical techniques used to estimate flow frequency. It assesses possible changes through time, comparing results across locations and distinguishing the evidence for increasing, decreasing, and uncertain trends.

Readers will find a technical reference on the magnitude, frequency, and nonstationarity of river flows. Methods, results, tables, and references explain how the estimates were developed and the range of records available for different analyses. The publication considers both flood peaks and low-flow durations, allowing the two ends of the basin's flow regime to be examined together.
