In 1978, only about 10,000 acre-feet of water was used for irrigation, stock, domestic, and public supplies; most of this water came form Lake Oahe on the Missouri River, and was used for irrigation. The lake stores about 22 million acre-feet of water; the average annual flow of the Missouri River is about 16 million acre-feet. Tributary streams normally are dry at least 10 months per year. Average annual net surface runoff from the county is 7,900 acre-feet. At least 99 percent of the precipitation per year is lost by evapotranspiration. An estimated 1.2 million acre-feet of water is stored in eight aquifers in the glacial drift. The water generally is suitable for irrigation, stock, and domestic use. It is estimated that more than 55 million acre-feet of water is stored in nine aquifers in the bedrock. These aquifers are in the Dakota Formation, Inyan Kara Group, Sundance and Minnelusa Formations, Madison Group, Devonian strata, and Stony Mountain, Red River, and Deadwood Formations. The water is slightly to very saline and, at best, is suitable for livestock and marginally acceptable for domestic supplies.

The three governing equations are coupled through the interstitial pore velocity, the dependence of the fluid density on pressure, temperature, the solute-mass fraction , and the dependence of the fluid viscosity on temperature and solute-mass fraction. The solute transport equation is for only a single, solute species with possible linear equilibrium sorption and linear decay. Finite difference techniques are used to discretize the governing equations using a point-distributed grid. The flow-, heat- and solute-transport equations are solved , in turn, after a particle Gauss-reduction scheme is used to modify them. The modified equations are more tightly coupled and have better stability for the numerical solutions. The basic source-sink term represents wells. A complex well flow model may be used to simulate specified flow rate and pressure conditions at the land surface or within the aquifer, with or without pressure and flow rate constraints. Boundary condition types offered include specified value, specified flux, leakage, heat conduction, and approximate free surface, and two types of aquifer influence functions. All boundary conditions can be functions of time. Two techniques are available for solution of the finite difference matrix equations. One technique is a direct-elimination solver, using equations reordered by alternating diagonal planes. The other technique is an iterative solver, using two-line successive over-relaxation. A restart option is available for storing intermediate results and restarting the simulation at an intermediate time with modified boundary conditions. This feature also can be used as protection against computer system failure. Data input and output may be in metric (SI) units or inch-pound units. Output may include tables of dependent variables and parameters, zoned-contour maps, and plots of the dependent variables versus time.

Results of reconnaissance test drilling indicate that the Upper Floridan aquifer may be treated as an unconfined aquifer in the management area which allows it to be divided into two types of geohydrologic areas: (1) areas of high recharge, and (2) areas of moderate recharge. Conceptually, the source of water to well fields in areas of high recharge would largely be natural recharge, whereas, in areas of moderate recharge, a significant part of the source of water to well fields would be induced downward leakage, or capture, of surface and near-surface water. The Withlacoochee River Basin of the Southwest Florida Water Management District is drained almost entirely by the Withlacoochee River and its tributaries. Field data were collected from April 13 through August 17, 1981, to document extremely low streamflow conditions. Conditions in the upper half of the drainage basin were found to be the most severe of record. On July 7, 1981, the total net runoff from the upper half of the basin was observed to be only 0.1 cu ft/sec. Low-flow conditions in the lower half of the drainage basin, however, were less severe than during the record low period of 1956.

The model simulates hydraulic heads and changes in hydraulic heads for 1907 to 1979. Hydraulic-conductivity values used in the accepted model range from 0.25 ft/day in part of the Santa Fe Group to 50 ft/day in the fluvial deposits in the Rio Grande flood plain. The majority of the basin-fill material of the Santa Fe group of Tertiary and Quaternary age was modeled as having a horizontal hydraulic conductivity of either 30 or 40 ft/day. The simulated specific storage of the aquifer was 0.000001/ft and the simulated specific yield was 0.10. The aquifer was simulated as being vertically anisotropic with a ratio of vertical to horizontal hydraulic conductivity of 1:500. Simulations for 1976-79 indicated that of the 100,000 acre-ft of groundwater withdrawn annually from the basin-fill deposits outside of the Rio Grande flood plain, 68% was obtained from recharge around the basin margin, depletion of streams that are tributary to the Rio Grande, and the stream-aquifer system in the Rio Grande flood plain. Depletion of aquifer storage accounted for 25% of the groundwater supply to wells outside of the flood plain, and the remaining 7% was obtained by induced groundwater inflow from the Santo Domingo Basin. The model displayed an acceptable performance throughout the period of simulation. However, by the end of the simulation period, 1979, the portrayal of the Rio Grande flood-plain system as a specified hydraulic-head boundary was having adverse effects on the simulation.

Interpretation of geologic and geophysical information indicates that the main structure of McMullen Valley is a syncline that has been normal faulted on the southeast side. Basin fill that accumulated in the structural depression during late Miocene to Pleistocene time is the main aquifer and is divided into upper and lower units on the basis of lithologic information. The upper unit is a thin layer of coarse-grained sediments and generally is not saturated. The lower unit is 3,000 to 4,000 ft thick, includes a fine-grained facies in the upper 1,000 ft, and is the main source of water. The fine-grained facies is found in the southwest half of the basin and is further divided into upper and lower parts. The lower part of the fine-grained facies has: a higher percentage of silt and clay than the upper part, contains evaporites, does not yield water to wells, and separates the aquifer into shallow and deep systems. A numerical model was used to analyze the groundwater system for both steady-state and transient conditions. The transient model was used to analyze system response to pumping stress. The transient system is one of storage depletion, and water level declines are controlled by pumping and specific yield distributions. Water level declines are also influenced by hydraulic properties and areal extent of the fine-grained facies. Significant water level declines may extend to aquifer boundaries in most of the basin; in one area, impermeable boundary greatly influences declines. The location of the nearby boundary was estimated through gravity data modeling. Several hydrologic components, including hydraulic properties and areal extent of the fine-grained facies , storage properties, and aquifer boundaries, need better definition in order to develop a more accurate model of the groundwater system.

In addition, selected intervals in these boreholes were logged with a borehole acoustic televiewer that produces a high-resolution image of the borehole wall, an acoustic waveform-logging system using 34-kiloHertz magnetostrictive and 5-kiloHertz sparker sources, and a highly sensitive heat-pulse flowmeter. Emphasis was on identifying and characterizing fracture zones that represent groundwater conduits in deeper portions of the granite, and on characterizing the properties of the largest intervals of unfractured granite. Major fracture zones were indicated by correlating geophysical log anomalies detected on the suite of conventional logs (unpublished data from Atomic Energy of Canada). However, several other anomalies, were identified as mafic intrusions of approximately the same thickness as major fracture zones. Geophysical log anomalies were compared for all major fracture zones that could serve as significant groundwater conduits, and fracture zone permeability is estimated on the basis of acoustic tube-wave attenuation in these intervals. Acoustic televiewer logs obtained at depths below 1,000 m in the deeper well indicate that most of the few fractures identified on core at these depths do not remain open enough under in situ conditions to produce detectable anomalies in acoustic refraction. Flowmeter data indicate that some groundwater circulation occurs in the upper portion of both boreholes. Water in the shallower of the two holes was observed to flow at 2.0 L/min; most of this flow entered the borehole at a depth &lt; 25 m, and no flow occurred below a depth of 100 m.

Pumpage from shallow wells near the inland bays has caused localized saltwater intrusion into the unconfined aquifer. Chloride concentrations in the Ocean City aquifer at 44th Street increased from 50 to 200mg/L from 1976 to 1986. Chloride concentrations in water from wells in the Manokin aquifer ranged from 6 to 460 mg/L, whereas those in the Ocean City aquifer ranged from 6 to 260 mg/L. Chloride concentrations in water from the Pocomoke aquifer ranged from 5 to 46 mg/L, and from 11.5 to 46 mg/L in the unconfined aquifer. Seasonal high water levels are affected more by total annual rainfall than by pumpage. Seasonal low water levels generally have declined during most years in areas of heavy pumpage along the coast.

The freshwater lens covers an area of about 22 sq mi surrounding the town of Geneva, and generally is enclosed by the 25 ft land surface altitude contour. Thickness of the lens is about 350 ft in the center of the recharge area. The geohydrologic units in descending order consist of the post-Miocene sand and shell of the surficial aquifer; Miocene clay, sand, clay, and shell that form a leaky confining bed; and permeable Eocene limestones of the Floridan aquifer system. The freshwater lens is the result of local rainfall flushing ancient seawater from the Floridan aquifer system. Sufficient quantities of water for domestic and small public supply systems are available from the Floridan aquifer system in the Geneva area. The limiting factor for water supply in the area is the chemical quality of the water. Chloride concentrations range from &lt; 20 mg/L in the center of the recharge area to about 5,100 mg/L near the St. Johns River southeast of Geneva. Constituents analyzed included sulfate (range 1 to 800 mg/L), hardness (range 89 to 2,076 mg/L), and iron (range 34 to 6,600 mg/L). Because the freshwater lens results entirely from local recharge, the long-term sustained freshwater yield of the aquifer in the Geneva area depends on the local recharge rate. In 1982, recharge was about 13 inches (13.8 million gal/day). Average recharge for 1941 through 1970 was estimated to be about 11 inches (11.3 million gal/day). Freshwater that recharges the aquifer in the Geneva area is either pumped out or flows north and northeast to discharge near or in the St. Johns River. Average annual outflow from the lens is about 10 in/yr. No measurable change in the size or location of the freshwater lens has occurred since studies in the early 1950's.

Data were collected at 19 gaging stations--18 stations in the Price, San Rafael, and Dirty Devil River basins, and 1 in the Kanab Creek Basin. Streamflow data were collected continuously at 11 stations and seasonally at 5 stations. At the other three stations streamflow data were collected continuously during the 1979 water year and then seasonally for the rest of their periods of record. Types of data collected at each station included quantity and quality of streamflow; suspended sediment concentrations; and descriptions of stream bottom sediments, benthic invertebrate, and phytoplankton samples. Also, base flow measurements were made annually upstream from 12 of the gaging stations. Stream bottom sediment sampled at nearly all the monitoring sites contained small to moderate quantities of coal, which may be attributed chiefly to pre-monitoring mining. Streamflow sampled at several sites contained large concentrations of sulfate and dissolved solids. Also, concentrations of various trace elements at 10 stations, and phenols at 18 stations, exceeded the criteria of the EPA for drinking water. This may be attributed to contemporary (water years 1979-84) mine drainage activities. The data collected during the complete water years (1979-84) of monitoring do provide a better understanding of the hydrologic systems of the coal field areas monitored. The data also provide a definite base by which to evaluate hydrologic impacts of continued or increased coal mining in those areas.

A technique is presented for estimating flood-peak discharges at recurrence intervals ranging from 2 to 500 years for nonregulated streams in Illinois with drainage areas ranging from 0.02 to 10,000 square miles. Multiple-regression analyses, using basin characteristics and peak streamflow data from 268 of the 394 gaged sites, were used to define the flood-frequency relation.

The parameters that changed under the steady-state condition were those that had been routinely adjusted during the calibration process as part of the effort to match pre-development potentiometric surfaces, and elements of the water budget. The tested steady-state parameters include: recharge, riverbed conductance, transmissivity, confining unit leakance, and boundary location. In the transient-state model, the storage coefficient was adjusted. The sensitivity of the model to changes in the calibrated values of these parameters was evaluated with respect to the simulated response of net base flow to the rivers, and the mean value of the absolute head residual. To provide a standard measurement of sensitivity from one parameter to another, the standard deviation of the absolute head residual was calculated. The steady-state model was shown to be most sensitive to changes in rates of recharge. When the recharge rate was held constant, the model was more sensitive to variations in transmissivity. Near the rivers, the riverbed conductance becomes the dominant parameter in controlling the heads. Changes in confining unit leakance had little effect on simulated base flow, but greatly affected head residuals. The model was relatively insensitive to changes in the location of no-flow boundaries and to moderate changes in the altitude of constant head boundaries. The storage coefficient was adjusted under transient conditions to illustrate the model 's sensitivity to changes in storativity. The model is less sensitive to an increase in storage coefficient than it is to a decrease in storage coefficient. As the storage coefficient decreased, the aquifer drawdown increases, the base flow decreased. The opposite response occurred when the storage coefficient was increased.

The quadrangle covers approximately 15,765 km<sup>2</sup> in east-central Alaska; most of it is included in the mountainous Yukon-Tanana Upland physiographic division, but the northernmost part is in the low-lying Yukon Flats section. The Circle mining district, in the east-central part of the quadrangle, has been a major producing area of placer gold since its discovery in 1893. </p><p>For descriptive purposes, the Circle quadrangle is divided into three areas: the northwest Circle quadrangle, the area north of the Tintina fault zone, and the area south of the Tintina fault zone. The Tintina fault zone extends northwesterly through the northern part of the quadrangle. The northwest Circle quadrangle contains mostly folded and faulted, slightly metamorphosed sedimentary rocks that are intruded by Tertiary granitic plutons. In the northern part of the area north of the Tintina fault zone (Little Crazy Mountains and northern east Crazy Mountains), the rocks consist primarily of the gabbro and basalt of the Circle Volcanics and minor associated chert, graywacke, and limestone. Elsewhere in this area (south of the Circle Volcanics and in the western Crazy Mountains), the rocks are mostly slightly metamorphosed Paleozoic sedimentary rocks that have been folded and faulted. Rocks in the largest part of the quadrangle, the area south of the Tintina fault zone, consist largely of pelitic rocks that are regionally metamorphosed to greenschist and amphibolite facies. Felsic plutons, mostly Tertiary in age, occur throughout the area. The metamorphic rocks are separated from sedimentary rocks on the northwest by thrust faulting. </p><p>The aeromagnetic and gravity data show clear differences between the areas north and south of the Tintina fault zone. The metamorphic terrane to the south has low overall gravity and local gravity lows over exposed granitic plutons. It is hypothesized that magnetic chlorite schist infolded with nonmagnetic quartzite and schist account for east-northeast-trending magnetic highs that approximately parallel the regional strike of the most prominent foliation in the metamorphic rocks. North of the Tintina fault zone, the Circle Volcanics are characterized by high gravity and east-west-trending magnetic highs. The Tintina fault zone has an intense magnetic high near the western margin of the Circle quadrangle overlying the magnetic granodiorite of the Victoria Mountain pluton. A magnetic high near Circle Hot Springs is less intense, but broader, and could reflect a buried magnetic pluton similar to that of the Victoria Mountain pluton. </p><p>Computer-enhanced Landsat images of the Circle quadrangle show trends and patterns of concentrations of linear features. Features trending northeast-southwest predominate throughout the quadrangle; northwest-southeast-trending linear features are found mostly south of the Tintina fault zone. High concentrations of linear features were not found to correspond to areas of known mineralization in any consistent or significant way that could presently be used in locating areas of mineralization. Geochemical and mineralogical studies of stream sediment and heavy-mineral concentrates from the Circle quadrangle identify areas of anomalous concentrations of metallic elements, including gold, silver, tin, tungsten, lead, antimony, zinc, thorium, uranium, and beryllium. The data delineate areas of known mineral occurrences and areas that may contain undiscovered mineral resources. </p><p>To date, placer gold has been the only significant metallic mineral resource from the Circle quadrangle, but the general geologic setting, especially the presence of post-orogenic plutons, is similar to that of regions that contain tin greisen deposits, tungsten skarn deposits, lode gold deposits in metasedimentary rocks, and uranium vein deposits. Six areas or tracts were identified in which such deposits might occur, and two more tracts were delineated as possible for the occurrence of shale-hosted Lead-zinc deposits. The discovery of two diamonds in the gravels of Cooked Creek point to the slight possibility of finding placer or lode diamond deposits.&nbsp;</p><p>Although most of the past and present gold mining has taken place in four areas in the quadrangle, a sedimentary basin near the town of Central was identified as possibly containing buried placer gold deposits or sedimentary uranium deposits.&nbsp;</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/cir986","usgsCitation":"Foster, H.L., Menzie, W., Cady, J.W., Simpson, S.L., Aleinikoff, J.N., Wilson, F.H., and Tripp, R.B., 1987, The Alaska Mineral Resource Assessment Program: Background information to accompany folio of geologic and mineral resource maps of the Circle quadrangle, Alaska: U.S. Geological Survey Circular 986, iii, 22 p., https://doi.org/10.3133/cir986.","productDescription":"iii, 22 p.","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":31348,"rank":3,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/circ/1987/0986/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":139315,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/circ/1987/0986/report-thumb.jpg"},{"id":391760,"rank":2,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_24147.htm"}],"country":"United States","state":"Alaska","otherGeospatial":"Circle quadrangle","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -147,\n              65\n            ],\n            [\n              -144,\n              65\n            ],\n            [\n              -144,\n              66\n            ],\n            [\n              -147,\n              66\n            ],\n            [\n              -147,\n              65\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad5e4b07f02db6834b2","contributors":{"authors":[{"text":"Foster, Helen Laura","contributorId":21936,"corporation":false,"usgs":true,"family":"Foster","given":"Helen","email":"","middleInitial":"Laura","affiliations":[],"preferred":false,"id":148511,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Menzie, W.

Dissolution of these deposits is the fundamental cause of sinkhole development. Sinkholes and other karst features are more pronounced in the northern part of the study area, but sinkhole activity has occurred throughout the area. Fifty-eight sinkholes with known or suspected connection to the Upper Floridan aquifer are located in the study area. An internally drained basin near the city of Brandon and five sinkholes in Hillsborough, Pasco, and Hernando Counties were selected for detailed investigation. At all sites, chemical or biological constituents were detected that indicate pollutants had entered the aquifer. A generalized classification, based on the potential to pollute, was applied to the selected sites. Four of the sites have high potential and two have moderate potential to pollute the Upper Floridan aquifer. All of the sites investigated are capable of recharging large volumes of water to the Upper Floridan aquifer in short periods of time. Continued monitoring of the quality of water entering the sinkholes and of wells downgradient to the sinks is needed to assess the future impacts on the aquifer.
