Abstract
Torrential rains during late June and early July 1975, combined with wet antecedent conditions, caused severe flooding, mainly along the lower reaches of the Sheyenne and Maple Rivers and their tributaries in North Dakota, and in the Buffalo and Wild Rice River basins in Minnesota. The Red River of the North from the Fargo-Moorhead area to the Halstad, Minnesota area was also severely flooded. Because much of the region is extremely flat, large areas of the two States were inundated by flood waters. Damage, mostly agricultural, was widespread and damage estimates exceeded a quarter of a billion dollars.
Local, State, and Federal officials need factual information to evaluate, coordinate, and manage programs concerned with flood losses. The purpose of this report is to provide quickly a summary of some of the basic data collected on the June-July 1975 floods. Only a part of the information collected by the U.S. Geological Survey on the extent and magnitude of the floods is presented. This information includes the magnitude and frequency of the instantaneous maximum stages (water-surface elevations) and flow rates for 62 sites, measured sediment loads at 7 sites, and hydrographs of daily mean flow at 6 sites. Additional streamflow information associated with the floods will be provided subsequently in annual data releases of the Geological Survey. The report also describes availability of graphic or photographic data depicting the areal extent of inundation. Those data may be obtained from the Applications Assistance Branch, EROS Data Center, U.S. Geological Survey, Sioux Falls, S. Dak. 57198.
Only a minimal amount of rainfall data are summarized in this report to aid in documenting the flood event. These data were provided by the National Oceanic and Atmospheric Administration (NOAA), U.S. Department of Commerce, and by the Minnesota State Office of Climatology. This assistance in providing the data and in reviewing the form of its presentation is appreciated.
