Thirty-six test holes were augered by the U.S. Geological Survey in the vicinity of Sol,,r Creek, Rosebud Indian Reservation, Todd County, South Dakota. Wells prcducing more than S gallons per minute (0.32 litre per second) from the Tertiary deposits are rare. However, as much as 20 feet (6.1 metres) of permeable alluvial deposits were penetrated in several test holes. One test ell was...

Locating and delineating buried glacial-drift aquifers poses one of the major problems to hydrogeologists working in glacial terrain. To show the vertical and horizontal boundaries of aquifers, most techniques require a multiple set of maps, a fence diagram, or a combination of maps and sections. Calculations of the first two moments, mean and standard deviation, of a discontinuous...

This report describes methods for estimating flood-peak discharges having 2- to 50-year recurrence intervals on North Dakota streams draining less than 100 square miles ( 259 square kilometres). For gaged sites, frequency estimates are provided directly. For ungaged sites, flood peaks are estimated from multiple-regression equations using drainage-area size and, in two regions, soil...

Griggs and Steele Counties, located at the eastern edge of the Williston basin, are underlain by 400 to 2,600 feet of Paleozoic and Mesozoic rocks that dip gently to the west. The Cretaceous Greenhorn, Carlile, Niobrara, and Pierre Formations lie directly beneath the glacial drift, and shale of the Pierre Formation is exposed in several places along the Sheyenne River. The Pleistocene...

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...

Test drilling and geologic data indicate that there are two potential aquifers in the Belcourt, N. Dak. area capable of supplying a sufficient quantity of ground water for the city of Belcourt. The Fox Hills aquifer, located about 3 miles (4.8 kilometres) west of Belcourt, could yield a sufficient quantity, as much as 500,000 gallons per day (1,900 cubic metres per day), of ground water...

A 1,930-foot (588-metre) water-supply well was constructed at the Painted Canyon Overlook, Theodore Roosevelt National Memorial Park (South Unit), southwestern North Dakota. Aquifers underlying the site are in rocks of Late Cretaceous and Tertiary age. These rocks have an aggreqate thickness of about 2,000 feet (610 metres). The well screen is set in the Fox Hills Sandstone of Late...

A general flood-frequency analysis has provided a method for estimating flood magnitudes and frequencies on South Dakota streams. Related flood data useful in planning and design also are included in the report. Two distinct hydrologic regions are delineated within the State. The divisional boundary for these regions is, in general, the western divide of the James River basin. For each...

Effective improvement of economic and social conditions of Indians living on Crow Creek and Lower Brule Reservations has been hampered by lack of adequate and reliable information about the quantity and quality of water supplies available for development. Compounding the problem, and making especially pressing the need for discovery and development of new water supplies, is the recent...
