Geohydrologic use of lithofacies maps in glaciated areas

Subsurface conditions may differ considerably from conditions indicated by surficial geologic maps, particularly in glaciated areas. Therefore, it is advantageous to use a series of lithofacies maps as a sequence of overlays plotted on transparent paper. Such maps permit direct visual determination of the lithology and areal extent of aquifers and indicate areas of possible stream losses or gains. They indicate areas and boundaries of confining layers and, in some places, they may be used to delineate areas of water-table and artesian conditions. They are especially useful in determining buried channels in glaciated areas. The porosity of rock units making up an aquifer may be plotted on a lithofacies map, and the product of the volume of each lithologic type and the porosity provides an estimate of the total water in storage. In addition, if the water-bearing properties are known, the quantity of water moving through an aquifer and the amount available to wells may be determined. Lithofacies maps also aid in the explanation of complex changes in water quality.

Preliminary map showing availability of water from glacial-drift aquifers in Towner County, north-central North Dakota

This preliminary map is the first product of the ground-water resources study of Towner County, which has an area of 1,049 mi 2 (2,717 km 2 ) in north-central North Dakota (see location map). The study is part of a statewide program to determine the location, extent, chemical quality, and hydrologic characteristics of the ground-water reservoirs (aquifers) in North Dakota. The study was made by the U.S. Geological Survey in cooperation with the North Dakota State Water Commission, the North Dakota Geological Survey, and the Towner County Water Management District.

Preliminary map showing availability of water from glacial-drift aquifers in McHenry County, north-central North Dakota

This preliminary map is the first product of the ground-water resources study of McHenry County . This study is part of a statewide program to determine the location, extent, chemical quality, and hydrologic characteristics of the ground-water reservoirs (aquifers) in North Dakota. The study was made by the U.S. Geological Survey in cooperation with the North Dakota State Water Commission, the North Dakota Geological Survey, and the McHenry County Water Management District.

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 satisfactory for the intended use due to the presence of high concentrations of dissolved solids, and chloride or sulfate.

Ground-water availability in the Belcourt area, Rolette County, North Dakota

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 for Belcourt, but the quality is unsuitable for a public supply. The Shell Valley aquifer, located about 5 miles (8 kilometres) southwest of Belcourt, appears to contain the quantity and quality of ground water required for the city of Belcourt municipal supply.

Results of aquifer testing in the Belcourt area, Rolette County, North Dakota

The city of Belcourt, Agency headquarters for the Turtle Mountain Indian Reservation, is located in northeastern Rolette County, north-central North Dakota. At the request of the U.S. Public Health Service, the U.S. Geological Survey conducted a study in the vicinity of Belcourt to assist in location of a suitable water supply for the city.

Ground-water resources of Benson and Pierce Counties, north-central North Dakota

The purpose of this investigation is to provide information about the ground-water resources in Benson and Pierce Counties that is sufficient for planning the safe and intelligent development of water supplies for irrigation, domestic, stock, industrial, and municipal purposes. The investigation is part of a statewide program to determine the location and extent of ground-water aquifers; to evaluate the occurrence and movement of ground water within the aquifers, including sources of recharge and discharge; to determine potential yields to wells developed in the aquifers; and to determine the chemical quality of ground water. Benson and Pierce Counties cover an area of 2,512 square miles in north-central North Dakota. This study, which began in July 1967 and was completed in June 1971, was made cooperatively by the U.S. Geological Survey, the North Dakota State Water Commission, the North Dakota Geological Survey, and the Benson and Pierce Counties Water Management Districts. This interim report presents only the major conclusions of the study.

Geology and ground water resources of Kidder County, North Dakota

Kidder County was covered with glacial ice at least three times during the Wisconsin Stage of the Pleistocene, but the entire sequence of drifts has not been observed in one exposure. The drift which covers the area was deposited during three ice advances termed the Long Lake, Burnstad and Streeter advances. The position of the drift border of the Long Lake advance is marked by the prominent Long Lake end moraine on the western border of the county.
