This collection of 46 short papers is the first published chapter of "Geological Survey Research 1970." 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. Chapter A, to be published later in the year, will present a summary of significant results of work done in fiscal year 1970, together with

An evaluation of the streamflow data available in North Dakota was made to provide guidelines for planning future programs. The basic steps in the evaluation procedure were (1) definition of the long-term goals of the streamflow data program in quantitative form, (2) examination and analysis of all available data to determine which goals have already been met, and (3) consideration of alternate pr

Hydrophytes growing in natural ponds on the Coteau du Missouri in North Dakota have been studied. Previous studies in the same region showed how transpiration by hydrophytes could be separated from the total water loss from a natural pond, during the period that vegetation was growing in height, on the basis of a correlation between the height of vegetation and a mass‐transfer coefficient. It is s

Injecting liquid wastes deep underground is an attractive but not necessarily practical means for disposing of them. For decades, impressive volumes of unwanted oil-field brine have been injected, currently about 10,000 acre-feet yearly. Recently, liquid industrial wastes are being injected in ever-increasing quantity. Dimensions of industrial injection wells range widely but the approximate media

Except perhaps for the arid Southwest, water resources are generally sufficient to meet the needs of cities for the foreseeable future. Cities will continue to expand and additional rural areas will be converted to urban and suburban complexes. Demands for urban water will continue to rise and this will place a heavy strain on existing systems. Cities have always faced water problems. This has lar

In 1960 the U.S. Geological Survey, in cooperation with the South Dakota State Water Resources Commission and the South Dakota State Geological Survey, started a program for the hydrogeologic investigation of glacial drift in selected drainage basins in eastern South Dakota. This program was designed to delineate water-bearing deposits of glacial-outwash sand and gravel, and to determine their wat

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 covers the ent

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.

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
