"The purpose of this report is to present the results of a study of the performance of the three relief well systems [along the Missouri River] during the July 1951 and April 1952 floods, and to compare their performance with design predictions. [...] The report includes observed uplift and well-flow data, descriptions of relief well operations during the floods, and an analysis of the effectiveness of the well systems together with discussion and comments on several experimental and test wells" (p. 2).

Report discussing investigations seeking uranium in deposits of black shale around the geographical areas of the Western States

From abstract and introduction: Mineralogic and stratigraphic studies of the lower part of the Pierre Shale of Late Cretaceous age along the Missouri River indicate correlations different from those generally accepted. The purposes of this paper are to present evidence for the new correlations and to resolve problems of formal nomenclature that result from them.

From introduction: The Cordilleran Foreland (King. 1951, p. 58-62; Horberg and others, 1949, p. 192194) forms a broad north-south belt, parallel to and east of the Cordilleran geanticline (fig. 1), in which the predominant geologic structure is a series of anticlinal mountains and broad asymmetric basins that contrast sharply with the folds and overthrusts related to the Cordilleran geanticline. A tectonic map of most of the Cordilleran Foreland (fig. 2) is being compiled as an aid to study the geologic setting of uranium deposits within the region, and to determine what relationships may exist between the distribution of uranium deposits and the regional tectonic pattern (Osterwald, 1955). The map will show the distribution of faults, uranium deposits, areas of volcanic activity, and crestlines and troughs of folds.

From abstract: Most of the formations in the Wray area are fair foundation materials, although good construction materials are scarce. The gravel of the Grand Island formation and the gravels in the Ogallala formation contain large quantities of clay, silt, sand, and calcium carbonate, and have very few pebbles larger than one-half inch in diameter.

From purpose and scope: There are two principal purposes for this study. The first is to describe the hydrogeologic system of the study area. The second is to develop and demonstrate a capability for evaluating, quantitatively, the effects of different management alternatives on water levels and on streamflow in the study area.

Abstract: This report lists the machine-readable data files developed for the Madison Limestone and Northern Great Plains Regional Aquifer System Analysis (RASA) projects that are stored on magnetic tape and available from the U.S. Geological Survey. Record format, file content, and size are given for: (1) Drill-stem-test data for Paleozoic and Mesozoic formations; (2) geologic data from the Madison Limestone project; (3) data sets used in the regional simulation model; (4) hydraulic-head data for the Lower and Upper Cretaceous aquifers; and (5) geologic data for Mesozoic formations of the Northern Great Plains.

From abstract: The High Plains Regional Aquifer System Analysis study has developed a regional water-resources (and related) data storage and retrieval system to organize and preserve areal interpretive data. The system is general and can easily be adapted for other studies. This report documents the High Plains data base as well as the general system that is independent of the High Plains area.

From introduction: This is the second report by U.S. Geological Survey personnel in Nebraska that presents interpretive information for the High Plains aquifer system in the State...This report and the first report are complementary; information from both can be used to compute certain aquifer properties, knowledge of which is essential in the development of a management plan for the aquifer system.

Abstract: A digital simulation model was used to analyze regional ground-water flow in the Madison Group aquifer in the Powder River Basin and adjacent areas. Most recharge to the aquifer originates in or near the outcrop areas of the Madison in the Bighorn Mountains and Black Hills , and most discharge occurs through springs and wells. Results from the model calculations indicate that the total flow through the aquifer in the modeled areas was approximately 200 cubic feet per second (5.7 cubic metres per second). The aquifer can probably sustain increased ground-water withdrawals probably would significantly lower the potentiometric surface in the Madison aquifer in a large part of the basin. The digital model could better predict the effects of withdrawals if more accurate estimates of the storage coefficient, transmissivity, and leakance could be obtained.

From introduction: This report describes the results of 1980 sampling of ground-water pumpage for irrigation on the High Plains, one phase of the High Plains Regional Aquifer-System Analysis project. These data were collected to estimate the volume of irrigation water pumped during 1980 and to determine current trends in irrigation pumpage on the High Plains.

From abstract: From September 15 to September 28, 1978, geoMetrics, Inc., collected 4320 line miles of high sensitivity airborne radiometric and magnetic data in Wyoming and Nebraska within two 1° x 2° NTMS quadrangles (Torrington and Casper).

From abstract: Results of a reconnaissance geochemical survey of the Grand Island Quadrangle, Nebraska; Kansas are reported. Statistical data and areal distributions for uranium and uranium-related variables are presented for 564 groundwater and 532 stream sediment samples. Also included is a brief discussion on location and geologic setting.

From abstract: Results of a reconnaissance geochemical survey of the Lincoln Quadrangle are reported. Field and laboratory data are presented for 577 groundwater and 754 stream sediment samples. Statistical and areal distributions of uranium and possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed.

From abstract: Results of a reconnaissance geochemical survey of the Alliance Quadrangle are reported. Field and laboratory data are presented for 543 groundwater and 523 stream sediment samples.

From Purpose and Scope of Study: "The Torrington 1ºx2º Quadrangle in southeastern Wyoming and a small area of westernmost Nebraska was evaluated to determine areas favorable for the occurrence of uranium deposits. Geologic environments (areally or stratigraphically restricted parts of a geologic unit) were placed in categories of favorable, unfavorable, or unevaluated."

From Introduction: "The Hot Springs Quadrangle covers an area of approximately 18,500 km2 and is in southwestern South Dakota and northwestern Nebraska between latitudes 43º to 44ºN. and longitudes 102º to 104ºW. (Fig. 1). The quadrangle was evaluated at the surface and in the subsurface to a depth of 1500 m to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits."
