Nearly 80 years of streamflow records have been collected in Nebraska. Such records are of immeasurable value and are essential if water resources are to be planned wisely and managed efficiently. Their value for planning and management can be greatly enhanced if the records are analyzed statistically. This report presents statistics on the flow of streams in the Loup River basin. As major irrigation projects have been constructed in the basin since gaging of streamflow was begun, the complete record of water discharge at some gaging stations includes periods before and after streamflow was first affected by diversions to an upstream project. Streamflow records presented in this report have been computed from data that represent current conditions of development and water use.
