Quality of surface water in the Bear River basin, Utah, Wyoming and Idaho

Water-quality data have been collected intermittently at several sites in the Bear River basin since 1947. Because the Bear River flows through three States - Utah, Wyoming, and Idaho - water-quality programs have been confined for the most part within State boundaries. In 1967, the U.S. Geological Survey, as a part of its cooperative program with the Utah Department of Natural Resources, Division of Water Rights, designed a reconnaissance to obtain needed water-quality information for the entire basin. This report presents the results of the data-collection phase of the reconnaissance. Also included in this report are data collected intermittently or periodically prior to the reconnaissance by the U.S. Geological Survey, the U.S. Bureau of Reclamation, and the Federal Water Pollution Control Administration. An interpretive report is being prepared and will be published by the U.S. Geological Survey as a Hydrologic Atlas.

Hydrogeology and steady-state simulation of ground-water flow in the San Juan Basin, New Mexico, Colorado, Arizona, and Utah

As part of a multidisciplinary regional aquifer-system analysis, a three-dimensional steady-state ground-water-flow model was constructed for the San Juan Basin in parts of New Mexico, Colorado, Arizona, and Utah. The model simulated ground- water flow in 12 hydrostratigraphic units representing all of the major sources of ground water from aquifers of Jurassic and younger age. Ten map reports in the U.S. Geological Survey Hydrologic Investigations Atlas 720 series were prepared in conjunction with this investigation. The units that were described in the atlases were the San Jose, Nacimiento, and Animas Formations; Ojo Alamo Sandstone; Kirtland Shale and Fruitland Formation; Pictured Cliffs Sandstone; Cliff House Sandstone; Menefee Formation; Point Lookout Sandstone; Gallup Sandstone; Dakota Sandstone; and Morrison Formation. Additional descriptions of the alluvial and landslide deposits, Chuska and Crevasse Canyon Sandstones, Lewis and Mancos Shales, Wanakah Formation, and Entrada Sandstone are included in this report. Much of the information in the HA-720 series was generated from digital computer data bases that were directly usable by the computer for compilation of input data for the model. In essence, the major components of the ground-water- flow model were described and documented in the series of hydrologic atlases. The primary finding resulting from the ground-water-flow simulation was that boundary conditions and internal geometry of the aquifers are the major controls of steady-state ground-water flow and hydraulic heads in the San Juan Basin. Another significant finding was that the computed steady-state ground- water flux is a very minor component (about 1 percent) of the total water budget of the basin.

Geohydrologic systems in Kansas — Geohydrology of the lower aquifer unit in the western interior plains aquifer system

The purpose of the investigation is to provide a description of the principal geohydrologic systems in Upper Cambrian through Lower Cretaceous rocks in Kansas. This investigation was made as part of the Central Midwest Regional Aquifer-System Analysis (CMRASA). The CMRASA is one of several major investigations by the U.S. Geological Survey of regional aquifer systems in the United States. These regional investigations are designed to increase knowledge of the flow regime and hydrologic properties of major aquifer systems and to provide quantitative information for the assessment, development, and management of water supplies. The CMRASA study area includes all or parts of 10 Central Midwestern States (Jorgensen and Signor, 1981), as shown of the envelope cover. This Hydrologic Investigations Atlas, which consists of a series of chapters, presents a description of the physical framework and geohydrology of principal aquifers and confining systems in Kansas. Chapter H presents the geohydrology of the upper aquifer unit in the Western Interior Plains aquifer system. The physical framework of the aquifer system in relation to other systems is described by maps and sections showing areal extent and the thickness of rocks that compose the unit. The physical framework of the upper aquifer unit is described in detail in chapter D of the atlas (Hansen and others, in press). The hydrology of the system in relation to that of other systems is described in this chapter by maps showing the altitude of fluid levels and the direction of water movement within the unit. The chemical composition of water in the system is described by maps that show the distribution of dissolved-solids concentrations and the differences in water types on the basis of principal chemical constituents. Chapter A of this atlas series (Wolf and others, 1990) describes the relation of principal geohydrologic systems in Kansas and presents a more detailed discussion of the methods and data used to prepare and ensure consistency among the sets of maps.

The CMRASA study area includes all or parts of 10 Central Midwestern States (Jorgensen and Signor, 1981), as shown on the envelope cover. This Hydrologic Investigations Atlas, which consists of a series of nine chapters, presents a description of the physical framework and the geohydrology of principal aquifers and confining systems in Kansas. Chapter D presents maps that show the areal extent, altitude and configuration of the top, and thickness of Mississippian rocks that compose the upper aquifer unit of the Western Interior Plains aquifer system in Kansas, The chapter is limited to the presentation of the physical framework of the upper aquifer unit. The interpretation of the physical framework of the upper aquifer unit is based on selected geophysical and lithologic logs and published maps of stratigraphically equivalent units. Maps indicating the thickness and the altitude and configuration of the top of the upper aquifer unit in the Western Interior Plains aquifer system have been prepared as part of a series of interrelated maps that describe the stratigraphic interval from the Precambrian basement through Lower Cretaceous rocks. A concerted effort was made to ensure that maps of each geohydrologic unit are consistent with the maps of underlying and overlying units. Chapter A of this atlas series (Wolf and others, 1990) describes the relation of principal geohydrologic systems in Kansas and presents a more detailed discussion of the methods and data used to prepare and ensure consistency among the sets of maps.

Delineation of flooding within the Ozark National Scenic Riverways in southeastern Missouri - Round Spring and Powder Mill

This is the second report in a series of U.S. Geological Survey Hydrologic Investigations Atlases to further supplement the National Park Service general management and development concept plan for the Ozark National Scenic Riverways (National Park Service, 1981) in southeastern Missouri (fig. 1). The technical basis on which the National Park Service can develop flood-management plans for use in evaluating their existing or future developments at Akers and Alley Spring recreational areas is given in Hydrologic Investigations Atlas HA-712-A (Alexander, in press). The Ozark National Scenic Riverways, administered by the National Park Service, is an extensively used recreational area where approximately 2 million visitors per year (M.E. Hunter, National Park Service, oral commun., 1985) participate in a wide range of river-use and land-based activities. Visitor areas along the 134-mi (mile) reach of the Current River and its principal tributary, Jacks Fork, range from highly-developed areas mostly along the upper Current River to primitive camping areas and river accesses along the Jacks Fork and downstream reach of the Current River. Most facilities at these developments are in or near flood-prone areas. Therefore, because of visitor safety, a major consideration of the National Park Service is the implementation of a flood-warning system.

Water resources of Massachusetts

This report describes the water resources of Massachusetts. It contains sections describing the location, use, quality, and management of water resources in Massachusetts, followed by a summary of the surface water and ground-water resources of all 27 river basins designated by the State for planning purposes. The data for each basin include information about selected continuous record streamflow-gaging stations, the distribution and size of major lakes and streams, and the character of the principal aquifers. Each basin summary is accompanied by a map that shows basin and political boundaries, hydrography, locations of continuous-record streamflow-gaging stations, and aquifer areas. The aquifer areas were derived from the Hydrologic Investigations Atlases and generally show areas that are likely to yield 100 gallons per minute or more to individual wells. The report was compiled from many reports, including 30 U.S. Geological Survey Hydrologic Investigations Atlases that inventory water resources of the State.

Major geohydrologic units in and adjacent to the Ozark Plateaus province, Missouri, Arkansas, Kansas and Oklahoma: Ozark aquifer

An investigation of the geohydrologic system in the Ozark Plateaus province (index map and Fenneman, 1938) has been made as part of the Central Midwest Regional Aquifer-System Analysis (Jorgenson and Signor, 1981), a major study that encompasses parts of 10 States. The study is one of several by the U.S. Geological Survey that are designed to increase knowledge of the flow regime and geohydrologic properties of regional aquifer systems in the United States. Because a large quantity of fresh groundwater is available in aquifers underlying the Ozark Plateaus province, a subregional project has been established to study the geohydrologic units of this area in more detail than is practical in the regional study. The stratigraphic relationship among the primary geohydrologic units in the Ozark Plateaus province is discussed in Chapter A of this Hydrologic Investigations Atlas series. This chapter focuses on the Ozark aquifer, a geohydrologic unit within the Ozark Plateaus aquifer system underlying the Ozark Plateaus province.

Delineation of flooding within the upper Mississippi River Basin, 1993 — Flood of June 29-September 18, 1993, in Iowa City and vicinity, Iowa

The hydrologic investigations atlas shows the areas in and around Iowa City, Iowa, that were flooded by the Iowa River in 1993. This map also depicts the Federal Emergency Management Agency (FEMA) 100-year flood boundaries. The drainage basin of the Iowa River at Iowa City received well over 100 percent of normal rainfall in June, July, and August, 1993. At the Cedar Rapids airport, located about 20 miles north-northwest of Iowa City, July rainfall was 414 percent of normal. The discharges at U.S. Geological Survey streamflow-gaging stations on the Iowa River upstream of Coralville Reservoir, just downstream from Coralville Reservoir, and at Iowa City are shown. A profile of the maximum water-surface elevations of the 1993 flood in Iowa City and vicinity is higher than the FEMA 100-year flood profile. The water-surface elevation of Coralville Reservoir is shown from June 29-September 18, 1993.

Delineation of flooding within the upper Mississippi River Basin—Flood of June 19-July 31, 1993, in Davenport, Iowa, and vicinity

The hydrologic investigations atlas shows areas in and near Davenport, Iowa, that were flooded by the Mississippi River in 1993. This atlas also depicts the Federal Emergency Management Agency 100-year flood boundary. The drainage basin upstream from Mississippi River Lock and Dam 15 at Davenport received between 100 and 250 percent of normal rainfall from January through July, 1993. The profile of the maximum water-surface elevations of the 1993 flood in the Davenport area is less than the Federal Emergency Management Agency 100-year flood profile. The Mississippi River Lock and Dam 15 tailwater elevation was above the flood elevation from June 19 to July 31, 1993, but did not exceed the 100-year flood elevation. For most of the time during October 1992 through September 1993, the daily mean discharge of the Mississippi River at Clinton, Iowa, greatly exceeded the monthly mean discharges from October 1874 through September 1993, but was less than the 100-year flood discharge. The daily mean discharge at Keokuk, Iowa, exceeded the 100-year flood discharge for nearly the entire month of July 1993.

Geohydrologic systems in Kansas, geohydrology of the Great Plains aquifer system

Sedimentary rocks of Late Cambrian through Early Cretaceous age in Kansas are part of a regional flow system of hydraulically connected aquifers and confining units. Future demands for water require that these deeply buried rocks be studied to describe hydrologic properties and ground-water-flow conditions and to provide information that will serve as the basis for decisions concerning the protection and the management of the water resources contained therein, Toward this end, the U.S. Geological Survey, as a part of its Central Midwest Regional Aquifer-System Analysis (CMRASA), began a 5-year hydrologic investigation of this regional flow system in Arkansas, Colorado, Kansas, Missouri, Nebraska, New Mexico, Oklahoma, South Dakota, and Texas (Jorgensen and Signor, 1981). This chapter is one of nine contained in Hydrologic Investigations Atlas HA-722, which present a description of the physical framework (Chapters B-F) and the geohydrology (Chapters G-I} of principal aquifers and confining systems in Upper Cambrian through Lower Cretaceous rocks in Kansas; the stratigraphic relations of these geohydrologic systems are discussed in detail in Chapter A (Wolf and others, 1990). This chapter (G) describes the geohydrology of the Great Plains aquifer system; the physical framework of the Great Plains aquifer system is presented in Chapter B (Spinazola and others, 1992). The maps in this chapter are based on existing data from selected geophysical and lithologic logs, drill-stem tests, water-level measurements, water-quality analyses, and published maps of stratigraphically equivalent units. An index to the geohydrologic data compiled for the CMRASA in Kansas is presented in Spinazola and others (1987). For the most part, data used to construct the maps were collected over many years and do not reflect aquifer conditions for any specific time period.

Hydrogeology of the Pine Ridge Indian Reservation, South Dakota

An investigation of the geology and ground-water resources of the Pine Ridge Indian Reservation, South Dakota, was made at the request of the Bureau of Indian Affairs as part of the U.S. Department of the Interior's program for the development of the Missouri River basin. The area of investigation (about 3,930 square miles) includes all the land within the original boundaries of the Reservation, except for that part of Bennett County south of the U.S. Highway 18, where there are only small tracts of Indian land. Emphasis in the study was placed on mapping major rock units and on determining their potential as sources of water for domestic and stock use. The geologic map on sheet 1 shows the areal extent of the major rock units, and a summary of the stratigraphy and physical characteristics of the exposed geologic formations is given in the table on this sheet. The writers appreciate the cooperation of the personnel of the South Dakota State Geological Survey, who provided most of the well data for Bennett County, information about the stratigraphy and geology of selected areas, and copies of published and unpublished geologic maps. (See map showing areas mapped prior to this investigation.) Also, they appreciate the cooperation of ranch owners and tenants, who permitted access to their lands, and the personnel of the Bureau of Indian affairs, who supplied soils mps and other data. Data on which this report is based, including logs of wells and test holes, chemical analyses of water and records of wells and springs, have been summarized by the authors in a basic-data report published jointly by the South Dakota Geological Survey and South Dakota Water Resources Commission (Water Resources Report 4, Basic hydrogeologic data - Pine Ridge Indian Reservation, South Dakota). A selected bibliography of reports pertaining to the geology of the area has been included in the basic-data report. This atlas will be more useful if studied in conjunction with a copy of the basic-data report.
