The main objectives of this study were to determine the flow variation of the Big Sioux River throughout the year, and to estimate the probable effects of increased water resources development on this flow. Flow-duration tables were prepared for six different flow-gaging stations located on the Big Sioux River and one station located on the Skunk Creek tributary. These tables were prepared for periods of one third of a month throughout the year. The mean or average flows for these time periods were also determined. It should be emphasized that the conclusions drawn from this investigation are based on the assumption that past river flows are representative of future flows and that the excess flow in the Big Sioux River in the spring is not stored and later released.
