Cass County comprises an area of 1,749 square miles in the southeastern corner of North Dakota. About one-fourth of the county is in the Drift Prairie physiographic province; the rest is in the Red River Valley (Lake Agassiz basin) physiographic division.

This report presents all the information, obtained during the investigation, that lends itself to generalization. It describes conditions on that part of the Coteau du Missouri where there is little integration of drainage systems. The surface of the glacial drift in this region is dotted with shallow depressions known as prairie potholes that hold water for varying lengths of time. Precipitation

This circular attempts to summarize existing knowledge of the effects of urbanization on hydrologic factors. It also attempts to express this knowledge in terms that the planner can use to test alternatives during the planning process. Because the available data used in this report are applied to a portion of the Brandywine Creek basin in Pennsylvania, this can be considered as a report on the bas

Estimates of water use in the United States for 1965 indicate that an average of about 310 bgd (billion gallons per day) were withdrawn for public-supply, rural domestic and livestock, irrigation, and industrial (including thermoelectric power)uses--that is, about 1,600 gallons per capita per day. This represents an increase of 15 percent over the withdrawal of 270 bgd reported for 1960. Fresh wat

In 1965, a ground-water recharge facility was constructed and placed in operation to forestall an impending water shortage at Minot, North Dakota. The facility is unique in that the rate of recharge to a buried sand and gravel aquifer is augmented by perforating an overlying bed of clay using hydraulic connectors (gravel-filled bored holes) in conjunction with an open-pit excavation. The connector

A hydrologic study of the Big Sioux aquifer system was begun July 1, 1966, by the U.S. Geological Survey, in cooperation with the City of Sioux Falls and the East Dakota Conservancy Sub-District.   Test drilling being done in the search for a southern outlet to the Big Sioux aquifer has led to the discovery of the outlet and of a deeper aquifer than was previously know to exist in this area.  This

The mass-transfer method was used to study the hydrologic behavior of 10 prairie potholes in central North Dakota during the 5-year period 1960-64. Many of the potholes went dry when precipitation was low. The average evapotranspiration during the May to October period each year was 2.11 feet, and the average seepage was 0.60 foot. These averages remained nearly constant for both wet and dry year

This collection of 48 short papers is the third published chapter of "Geological Survey Research 1968." The papers report on scientific and economic results of current work by members of the Geologic and Water Resources Divisions of the U.S. Geological Survey.

Refractory flint clay and semiflint clay layers, totaling as much as 7% feet in thickness, occur in the lower part of the Allegheny Formation of Pennsylvanian age in north-central Randolph County, W.Va. The deposit seems to be a lens in a widespread bed of plastic clay and may underlie an area of 1-2 square miles. Refractory tests of three samples indicate a pyrometric cone equivalent of cone 30-3

Above-normal precipitation in 1954, 1956, and 1957 caused the water surface of Devils Lake to rise to an altitude of 1,419.3 feet, its highest in 40 years. Nearly all the water entering the lake flowed through Big Coulee, and about three-fourths of that inflow was at rates greater than 100 cubic feet per second. At these rates, the inflow contained less than 600 ppm (parts per million) dissolved s

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 water from
