This preliminary map is the first product of a study of the ground-water resources of Sheridan County.  The study is part of a statewide program to determine the location, extent, and hydrologic characteristics of the ground-water reservoirs (aquifers) in North Dakota.

Because of growing interest in the role of lakes and wetlands in the hydrology of the prairie environment, a group of wetlands in the Cottonwood Lake area, Stutsman County, are being instrumented for long-term hydrologic studies. The study site is on a regional topographic high near the eastern edge of the Missouri Coteau and is underlain by more than 400 feet of glacial drift, largely clayey, sil

The Great Plains! The words alone create a sense of space and a feeling of destiny a challenge. But what exactly is this special part of Western America that contains so much of our history? How did it come to be? Why is it different? Geographically, the Great Plains is an immense sweep of country; it reaches from Mexico far north into Canada and spreads out east of the Rocky Mountains like a huge

Procedures are defined for estimating the magnitude and frequency of future flood peaks and flood volumes and for estimating the expected hydrograph shape of rainfall-induced runoff of small streams in South Dakota. The procedures are applicable to flood flows that are not significantly affected by artificial storage or other manmade activities. For 115 gaged sites within the State, the estimates

In order to design a network to monitor the effects of works of improvement in the Middle and North Branch Park River watersheds, and to determine the major factors controlling water-quality conditions in the watersheds, an evaluation of sediment transport, water chemistry, and biology was conducted during the spring and early summer of 1978.Major factors controlling water quality are geology, str

Effective improvement of economic and social conditions of Indians living on the Cheyenne River Indian Reservation has been hampered by lack of adequate and reliable information about the quantity and quality of water supplies available for development.  Compounding the problem is the recent fillinf of Oahe Reservoir, which flooded about 105,00 acres of Indian land, and the consequent relocation o

The settlement and development of South Dakota has been closely related to both its mineral and water resources In 1874 the discovery of gold in the Black Hills led to the opening and development of the area west of the Missouri River. Towns and farms both here and east of the Missouri were located near dependable water supplies which the settlers learned were not as plentiful as in the more humid

A finite-difference digital model simulated hydrologic conditions in the Edgeley aquifer, which is an unconfined glacial-drift aquifer. The calibrated model supported the hypothesis that under natural steady-state conditions, recharge is from precipitation and discharge is through evapotranspiration. This hypothesis was further supported by comparing simulated water levels to observed water levels
