Abstract
The Little Missouri River flows through Theodore Roosevelt National Park t which consists of three separate units: South Unit, Elkhorn Ranch Site, and North Unit. The park is located in the Little Missouri badlands. Discharges and water-surface elevations for 100- or 500-year floods or both were computed for selected reaches along the Little Missouri River and three of its tributaries (Knutson Creek, Paddock Creek, and Squaw Creek) within and adjacent to Theodore Roosevelt National Park. The 100- and 500-year flood discharges for the Little Missouri River were determined from streamflow records. The 100-year flood discharges for the three creeks were estimated using a multiple-regression equation based on drainage area and soil-infiltration index. Water-surface elevations were determined by the step-backwater method. The effects of ice jams on water-surface elevations were estimated from streamflow records.
