Map Showing Total Thickness of the Fox Hills-Lower Hell Creek Aquifer, Montana
Introduction: In 1978 the U.S. Geological Survey began a 4-year study of aquifers in the northern Great Plains. The purpose of this map, which is a product of that study, is to show the total thickness of the Fox Hills-lower Hell Creek aquifer. Other maps show the altitude of the top (Feltism 1982a), cumulative thickness of sandstone (Feltis, 1982b), and potentiometric surface of water (Levings, 1982) in the Fox Hills-lower Hell Creek aquifer. These maps are part of a series that describes the geology and potentiometric surface of selected rock units of Jurassic or younger age in the plains area of Montana.

Evaluation of the Response of the Big Sioux Aquifer to Extreme Drought Conditions in Minnehaha County, South Dakota
From purpose and approach of study: The purpose of this study was to use the digital-computer model developed from the previous study (Koch, 1982) to examine the effects on the aquifer of a pumping rate of 25 million gallons a day under the worst-drought conditions that occurred during 1974-78. A frequency rating was determined for the most severe low-flow condition in the Big Sioux River.

Flood Elevations for the Soleduck River at Sol Duc Hot Springs, Clallam County, Washington
Abstract: Elevations and inundation areas of a 100-year flood of the Soleduck River, Washington, were determined by the U.S. Geological Survey for the area in the vicinity of the Sol Duc Hot Springs resort, a public facility in the Olympic National Park that under Federal law must be located beyond or protected from damage by a 100-year flood. Results show that most flooding could be eliminated by raising parts of an existing dike. In general, little flood damage is expected, except at the southern end of an undeveloped airstrip that could become inundated and hazardous due to flow from s tributary. The airstrip is above the 100-year flood of the Soleduck River.

Ground Water in the Northeast Part of Twentynine Palms Marine Corps Base, Bagdad Area, California
Purpose and scope: The U.S. Marine Corps conducts training maneuvers in the study area. Lack of a local source of water has severely limited the utilization of the area. In the past, limited quantities of water have been transported to the area by truck or helicopter. The purpose of this study was to determine the feasibility of obtaining a supply of ground water in the area for use when field maneuvers are being conducted. The major effort for this study was concentrated on the part within the Marine Corps base boundary. The study involved the assessment of ground-water quality, ground water in storage, and aquifer characteristics.

From introduction: The objective of this study are to (1) determine the areal extent and thickness of the Buffalo aquifer and the general occurrence of deeply buried aquifers, (2) determine the potential for development of water supplies from wells in the Buffalo aquifer, (3) investigate and discuss annual recharge to the Buffalo aquifer and the potential for artificially recharging the aquifer, (4) determine the chemical quality of water in the aquifer and in area streams, (5) establish a network of observation wells for monitoring water levels and water quality in the aquifer, (6) determine the relationship between the aquifer and the adjacent streams, and (7) update the information on the flow characteristics of the streams. The main focus of this study is on water in the Buffalo aquifer and on flow characteristics of streams.

Assessment of Water Quality in Streams Draining Coal-Producing Areas in Ohio
From introduction: In 1975 a project was begun to provide information on several aspects of coal hydrology in Ohio. The first phase was a reconnaissance of water-quality conditions in coal-mining regions. Phase one had two primary objectives; to document the occurrence of certain inorganic and organic constituents in waters of the coal-mining regions and to determine if the concentrations of those constituents were related to coal mining. The second phase of the project was a more detailed study of four basins sampled during the first phase.

Effects of Sanitary Sewers on Ground-Water Levels and Streams in Nassau and Suffolk Counties, New York, Part 1: Geohydrology, Modeling Strategy, and Regional Evaluation
From purpose and scope: This report is the first in a three-part series describing the U.S. Geological Survey's efforts in the detailed hydrologic investigation of southern Nassau and southwest Suffolk Counties, which includes a ground-water modeling study to predict the effects of an extensive sewer network scheduled to be completed in 1985. As the introduction to the series, this report has four objectives: (1) to present a detailed description of the hydrologic system in the area, including newly acquired hydrogeologic information; (2) to define the hydrogeologic factors that will be affected by the sewer network; (3) to explain the modeling strategy and describe the techniques used to develop the ground-water models of the two adjacent areas studied; and (4) to present a preliminary evaluation of the effects of sewers as predicted by a regional ground-water flow model.
