Summary appraisals of the nation's ground-water resources – Missouri basin region Summary appraisals of the nation's ground-water resources – Missouri basin region

The Missouri Basin Region lies in the north-central part of the United States and southern Canada. It includes parts of Alberta and Saskatchewan in Canada; parts of Montana, Wyoming, North Dakota, South Dakota, Minnesota, Iowa, Colorado, Kansas, and Missouri, and all of Nebraska in the United States. The region includes about one-sixth of the contiguous United States and requires large...

Numerical simulation of steady state three-dimensional groundwater flow near lakes Numerical simulation of steady state three-dimensional groundwater flow near lakes

Numerical simulation of three-dimensional groundwater flow near lakes shows that the continuity of the boundary encompassing the local groundwater flow system associated with a lake is the key to understanding the interaction of a lake with the groundwater system. The continuity of the boundary can be determined by the presence of a stagnation zone coinciding with the side of the lake...

Summary appraisals of the nation's ground-water resources – Souris-Red-Rainy region Summary appraisals of the nation's ground-water resources – Souris-Red-Rainy region

A broad-perspective analysis of the ground-water resources and present and possible future water development and management in the Souris-Red-Rainy Region is presented. The region includes the basins of the Souris River within Montana and North Dakota; the Red River of the North in South Dakota, North Dakota, and Minnesota; and the Rainy River within Minnesota. The region includes 59,645...

Ground-water resources of Griggs and Steele Counties, North Dakota Ground-water resources of Griggs and Steele Counties, North Dakota

Griggs and Steele Counties, in east-central North Dakota, are underlain by bedrock of Ordovician, Jurassic, and Cretaceous ages. The Fall River and Lakota Formations of Cretaceous age form the Dakota aquifer. The fractured upper part of the Pierre Formation (shale), also of Cretaceous age, forms another bedrock aquifer. The Dakota aquifer, which consists mainly of interbedded shale and...

Ground-water levels in the United States, 1972-74, north-central states Ground-water levels in the United States, 1972-74, north-central states

Publication of ground-water level data for the United States in water-supply papers was begun by the Geological Survey in 1935. From 1935 through 1939, a single water-supply paper for each year covering the entire nation was issued (Water-Supply Papers 777, 817, 840, 845, and 886). Since then water-supply papers have been issued covering 6 separate sections of the United States as shown...

Proceedings of the first annual William Pecora Memorial Symposium, October 1975, Sioux Falls, South Dakota Proceedings of the first annual William Pecora Memorial Symposium, October 1975, Sioux Falls, South Dakota

The U.S. Geological Survey agreed to publish the proceeding of the first annual William T. Pecora Memorial Symposium in its Professional Paper series because the subject material is related to the mission of the Survey. The usual standards for this series have been modified to accommodate the variety of styles used by the participants in this symposium. All color illustrations are placed...

Ground-water investigations at U.S. Air Force Launch Control Facility E-0, Ramsey County, North Dakota Ground-water investigations at U.S. Air Force Launch Control Facility E-0, Ramsey County, North Dakota

U.S. Air Force Launch Control Facility E-0 is located in Ramsey County, North Dakota. Geohydrologic and water-quality data indicate that the fractured Pierre Shale is the only aquifer in the vicinity of the facility that will supply acceptable water at the required rate of 5 gallons per minute (0.32 liters per second}. The chemical quality of the water is generally considered marginally
