Multiyear Low Flow Of Streams In Northeastern Kansas

Many existing water supplies in northeastern Kansas are proving inadequate to meet current and expanded future needs. One of the methods by which the use of highly variable streamflow in the area can be evaluated is with the aid of multiyear low-flow frequency information. Using data form 19 streamflow-gaging stations in the study area, maps were developed from which the mean annual discharge and discharges for the 2- and 50-year recurrence interval for durations of 12,24, 36, 48, and 60 months can be obtained for rural ungaged sites that have drainage areas of less than 1,000 square miles. Discharges for intervening recurrence intervals can be obtained by interpolation. Extrapolation of regionalized discharges in this report to drainage areas smaller than about 50 square miles and larger than about 1,000 square miles has not been validated. (USGS)
