Eddy and Foster Counties are in east-central North Dakota, high on the eastern flank of the Williston Basin. They are underlain by 3200 to 4300 feet of Paleozoic and Mesozoic rocks that dip gently to the west. The uppermost formation, the Cretaceous Pierre Shale, lies directly beneath the glacial drift and crops out in the valleys of the James and Sheyenne Rivers. Glacial drift that...

Valley City, North Dakota, has an average daily water use of 750,000 gallons, which is obtained from wells tapping pattly confined gravel deposits in the Sheyenne River valley. These deposits at Valley City have a maximum thickness of more than 50 feet and an areal extent of approximately 1 square mile. The aquifer has been artificially recharged successfully since 1932 by diversion of...

This collection of 49 short papers is the first published chapter of "Geological Survey Research 1967." The papers report on scientific and economic results of current work. by members of the Geologic, Topographic, and Water Resources Divisions of the U.S. Geological Survey.

The Minot area is in the north-central part of North Dakota and includes part of the Souris River valley. The region is covered by glacial drift of late Wisconsin age except in small areas where the Fort Union Formation of Tertiary age crops out. Thickness of the drift is controlled by the topography of the bedrock. In places the drift is more than 450 feet thick, but it averages about...

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...

Runoff is that part of precipitation that appears as a flow of water in surface streams. As a source of water for modern society, it constitutes one of our basic renewable resources. This map of average annual runoff portrays the latest information on the geographic distribution of the average runoff of surface streams.

The Heart River drainage basin of southwestern North Dakota comprises an area of 3,365 square miles and lies within the Missouri Plateau of the Great Plains province. Streamflow of the Heart River and its tributaries during 1949-58 was directly proportional to .the drainage area. After the construction of Heart Butte Dam in 1949 and Dickinson Dam in 1950, the mean annual streamflow near...

A severe thunderstorm accompanied by much hail swept through southwest-central North Dakota on the afternoon of June 24. Rainfall of up to 13 inches caused floods higher than any previously known in the area. The isohyetal map (fig. 1) indicates the extent and magnitude of the storm. This map was derived from rainfall data at 20 U.S. Weather Bureau gages (4 recording), 26 Geological...
