Little Sioux River Basin floods

January 1, 1966

Highway engineers and many others use flood stages and discharges in the design of bridges and other structures or operations on the flood plain of a stream. These data are provided in the form of gaging-station and other flood records and as flood profiles. Flood-frequency data are used to compute the 25- and 50-year recurrence interval discharges along the Little Sioux River from mile 24 to the Minnesota State line. The profiles of these two floods are computed and presented together with the profiles of the floods that occurred in 1965 and certain prior years. Less complete data are presented for the Ocheyedan and Maple Rivers, tributaries of the Little Sioux River.

Stage and discharge tabulations at 8 gaging stations for the 1965 flood can be used for volumetric computation. The same data can also be used to determine the time the flood was above a selected stage.
