The glacial deposits underlying a 260 square-mile area near Logansport, Indiana, range in thickness from 0 to 300 feet and consist of three semiconfined sand and gravel aquifer units separated and overlain by three semiconfining till units. The ground-water development potential of the lowest of the sand and gravel aquifers is considerable. Thickness of the aquifer is generally about 80 feet along the axis of the narrow buried valley that it fills. Maximum and average transmissivities of the aquifer are about 38,000 and 13,000 square feet per day, respectively. Withdrawal of 10 million gallons per day from the aquifer was simulated by a four-layer digital model of the study area. Simulated pumping centers were located in areas of high transmissivity and proximity to ground-water discharge. Results indicate an absence of hydrologic constraints to development of the quantities of ground water simulated in the model. However, the simulation of water-level declines of as much as 35 feet in the lowest aquifer indicates that interference with the operation of domestic wells is likely.

This model, using a weekly time step, simulated the transient interactions of these two systems for an initial-fill condition and general-operational condition. A sensitivity analysis was made to test the effects of possible errors in the description of aquifer characteristics on the model results. The initial-fill simulation indicated that to fill the reservoir when hydraulic connection between the surface-water system and the aquifer is simulated would take 2 additional years than if no connection was assumed. Simulated ground-water return flow to the river downstream of the proposed dam was about 85 percent of the estimated maximum values, computed under steady-state conditions in an earlier study. The general operation simulation indicated that during the period of lowest reservoir contents the aquifer provided about 80,000 acre-feet of recoverable storage to the reservoir 's capacity. Average return flow was only about 70 percent of the estimated maximum values computed in the earlier, steady-state analysis. Monthly ground-water outflow from the reservoir to the aquifer ranged from 55,200 to -10,400 acre-feet. Parameters tested for sensitivity, in order of decreasing sensitivity, were: Hydraulic conductivity, specific yield, hydraulic connection between reservoir and aquifer, local recharge, boundary conditions, and dam permeability. The probable error in the parameters tested would not seem to warrant significant new data collection.

Q-mode factor analysis of 29 samples of this granite shows that five bulk compositions are required to explain the observed variances of 33 constituents in these samples. Models presented in this paper show that the origin of the granite can be accounted for by the mixing of a starting liquid with two ranges of solid compositions such that all five compositions are granitic. \r\n\r\nThere are several features of the granite of Lankin Dome that suggest derivation by partial melting and, because the proposed source region was inhomogeneous, that more than one of the five end members may have been a liquid. Data for the granite are compatible with derivation from rocks similar to those of the metamorphic complex that the granite intrudes. Evidence for crustal derivation by partial melting includes a strongly peraluminous nature, extremely high differentiation indices, high contents of incompatible elements, generally large negative Eu anomalies, and high initial lead and strontium isotopic ratios. If the granite of Lankin Dome originated by partial melting of a heterogeneous metamorphic complex, the initial magma could reasonably have been composed of a range of granitic liquids. \r\n\r\nFive variables were not well accounted for by a five-end-member model. Water, CO 2 , and U0 2 contents and the oxidation state of iron are all subject to variations caused by near-surface processes. The Q-mode factor analysis suggests that these four variables have a distribution determined by postmagmatic processes. The reason for failure of Cs0 2 to vary systematically with the other 33 variables is not known. Other granites that have lost large amounts of uranium possibly can be identified by Q-mode factor analysis.","language":"ENGLISH","doi":"10.3133/pp1225","usgsCitation":"Stuckless, J., and Miesch, A., 1981, Petrogenetic modeling of a potential uranium source rock, Granite Mountains, Wyoming: U.S. Geological Survey Professional Paper 1225, 34 p., https://doi.org/10.3133/pp1225.","productDescription":"34 p.","costCenters":[],"links":[{"id":170415,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/pp/1225/report-thumb.jpg"},{"id":65424,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/pp/1225/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a81e4b07f02db649ee2","contributors":{"authors":[{"text":"Stuckless, J.

During the summer field seasons of 1976, 1977, 1978, and 1979, the U.S. Geological Survey under contract with the Bureau of Land Management through the National Oceanic and Atmospheric Administration conducted geo-environmental studies in lower Cook Inlet (note Table 1) (Bouma and Hampton, 1976; Bouma and others, 1978, Hampton and Bouma 1979, 1980).
The USGS research vessel SEA SOUNDER was used to obtain continuous seismic reflection profiles and to collect seafloor sediment samples. In addition, bottom samples were taken by the University of Alaska during benthic biological studies aboard the R/V MOANA WAVE (April 1976) and the NOAA vessel MILLER FREEMAN (October1976, Feder,1977). Textural analyses were carried out on sediment samples taken at 117 station locations. Sample collection was influenced by the nature of the substrate, texture, equipment malfunction and weather. Figure 2 presents a map with station locations. Station locations and other data are tabulated in Appendix I.
A modified Van Veen grab sampler, capable of taking an undisturbed surface sample of 40X60X30 cm was used to collect unconsolidated sediment. In addition, a 3-m gravity corer and a 2-m vibracorer were used at selected sites. The top ten centimeters of each sample were used for grain size analysis. Most samples were taken from bedform fields that occupy much of central lower Cook Inlet. Water depths in the lower inlet range from 40 to 170 m, averaging approximately 70 m. Strong tidal currents are present and surface water velocities of 3-5 knots (150-250 cm/sec) are common during flood and ebb tides (Bouma and Hampton, 1978).
The bottom of central lower Cook Inlet is almost completely covered by sand. Bedrock material can be observed at the seafloor on seismic records in isolated areas. The sand occurs in bedform patterns; textural data are important when determining the relationship between the currents and migrating sand bodies patterns. Immediate and long-term effects of sand movement over and around obstructions placed on the seafloor should be studied to prevent damage or destruction to the sensitive ecosystem of lower Cook Inlet.
This report presents textural grain-size data that have been gathered for lower Cook Inlet samples, the method of collection, and analytical processes. The data in Appendix 2 can be used to compare calculated parameters in order to properly assess the sedimentary environment of lower Cook Inlet.

Water-quality data from these studies showed that water in the basin is of good quality for most of the beneficial uses defined by the California State Water Resources Control Board. Concentrations of dissolved constituents are substantially higher in the water in the two largest tributaries than in Cache Creek. Seasonal variations in dissolved constituents are also greater in the tributaries than in Cache Creek. Clear Lake has a major effect on water quality, resulting in little seasonal fluctuation in water quality in Cache Creek. Excessive voron and suspended-sediment concentrations are the greatest water-quality problems, according to existing data. Both of these problems are from natural sources. Water-quality monitoring is presently being conducted monthly at four sites by the California Department of Water Resurces and at several other sites by other agencies. Modifications in current monitoring are proposed to gain further information on diel dissolved-oxygen cycles, pesticides, and biological constituents that may adversely affect beneficial uses.

The purposes of the survey were to define: (1) areas of sediment accumulation and erosion; (2) the thickness of Holocene sediments; (3) the internal structure of the near-surface sediments; (4) the types of bottom topography; and (5) the general geologic framework of the tidal river and estuary.
The survey utilized a variety of acoustic systems. Bottom data were obtained by using a Raytheon _1/ model DE-719 fathometer (200 kHz) and an EDO Western model 606 sidescan-sonar system (100 kHz). Subbottom data were collected with a 7-kHz Raytheon model PTR-106 system and a small airgun system (170-645 Hz band pass; l in3 chamber). An EDO Western sidescan fish (model 604-150) coupled with a 2.5-kHz seismic-reflection system also was used during the longitudinal run up the river. The totals for the ,various kinds of data collected were 481 line kilometers each of fathometer, sidescan sonar, 7-kHz, and airgun records, and 246 line kilometers of 2.5-kHz records. Positional control for all tracklines was provided by frequent radar fixes, by dead reckoning, and by sightings on buoys, landmarks, and other navigational aids.
The quality of the acoustic records varied with location in the river. Good fathometer and sidescan-sonar records were collected along all tracklines. However, because of the nature of the sediments within some sections of the river, the degree of subbottom penetration in many places was limited. In general, the subbottom penetration and resolution were poor in the upper and middle reaches of the river, whereas the subbottom records from the lower reach usually were quite good.
The original records may be examined at the U.S. Geological Survey, Woods Hole, MA 02543. Microfilm copies of the data are available for purchase from the National Geophysical and Solar-Terrestrial Data Center (NGSDC), Boulder, CO 80303.

Several wells and springs near active faults in southern California have been monitored for the concentration of Rn, Na+ , K+ , Mg+2 , and Cl- for periods of up to 24 months, in an effort to see if any of these constituents show variations which may be related to seismic activity. Radon might reflect either a change in the rock surface area to pore volume ratio or a change in groundwater flow characteristics. The chemistry may change with a change in the flow characteristics. Only a few of these sites have shown significant fluctuations in either radon or chemistry. Data from cold springs are consistent with a model in which ionic constituents are controlled by reactions in the soil zone and radon concentrations are controlled by flow rates in the aquifer.

A key element in the planning is the determination of whether water quality of the river is suitable for recreation. A preliminary water-quality assessment of the river in Indianapolis on August 4-5, 1980, indicates that, during low-flow steady-state conditions, water quality of the river is suitable for partial body contact recreation (any contact with water up to, but not including, complete submergence). Dissolved-oxygen concentrations varied but were higher than the Indiana water-quality standards established to ensure conditions for the maintenance of a well-balanced, warm-water fish community. High fecal-coliform densities that have been observed in the White River during high stream-flow are probably caused by stormwater runoff from combined sewers. However, during the low-flow steady-state conditions on August 4-5, 1980, fecal coliform densities were within the Indiana standards for partial body contact recreation. Concentrations of organic matter (based on biochemical-oxygen demand and dissolved- and suspended-organic carbon concentrations), nutrients, and heavy metals in the White River were generally within the limits recommended by the U.S. Environmental Protection Agency and were generally similar to values for other Indiana rivers. Chromium, copper, lead, zinc, and mercury are accumulating in bottom materials downstream from 30th Street (river mile 235.58). The source of these metals is probably stormwater runoff from combined sewer overflows. The phytoplankton densities of the White River were high (>500 cells per milliliter). The dominant phytoplankton species are indicative of rivers moderately affected by organic wastes. The highest cell concentrations, upstream from dams on the White River, significantly affected dissolved-oxygen concentration and pH.

Seven dikes form a radial pattern about Ship Rock we describe in detail the northeastern dike, which has an outcrop length of about 2,900 m, an average thickness of 2.3 m, and a maximum thickness of 7.2 m. The dike is composed of 35 discrete segments arranged in echelon; orientation. of dike segments ranges systematically from N. 52? E. to N. 66? E. A prominent joint set strikes parallel to the segments and is localized within several tens of meters of the dike. Regional joint patterns display no obvious relation to dike orientation. Small offsets of segment contacts, as well as wedge-shaped bodies of crumpled host rock within segments mark the sites of coalescence of smaller segments during dike growth. Bulges in the dike contact, which represent a nondilational component of growth, indicate that wall rocks were brecciated and eroded during the flow of magma. Breccias make up about 9 percent of the 7,176-m 2 area of the dike, are concentrated in its southwest half, and are commonly associated with its thickest parts. We also describe three subcircular plugs; each plug is smaller than 30 m in diameter, is laterally associated with a dike, and contains abundant breccias. Field evidence indicates that these plugs grew from the dikes by brecciation and erosion of wallrocks and that the bulges in the contact of the northeastern dike represent an initial stage of this process. \r\n\r\nFrom continuum-mechanical models of host-rock deformation, we conclude that dike propagation was the dominant mechanism for creating conduits for magma ascent where the host rock was brittle and elastic. At a given driving pressure, dikes dilate to accept greater volumes of magma than plugs, and for a given dilation, less work is done on the host rocks. In addition, the pressure required for dike growth decreases with dike length. From numerical solutions for dilation of cracks oriented like segments of the northeastern dike, we find that we can best model the form of the dike by treating it as composed of 10 cracks rather than 35. We attribute this result to coalescence of adjacent segments below the present outcrop and to inelastic deformation at segment ends. Using a driving pressure of 2 MPa (20 bars), we estimate a shear modulus of about 10^3 MPa for the host rocks, in agreement with laboratory tests on soft shale. A propagation criterion based on stress intensity at the segment ends indicates a fracture toughness of the host rocks of about 100 MPa-m^? , a hundredfold greater than values reported from laboratory tests. Segmentation of fractures is common in many materials and has been observed during fissure eruptions at Kilauea Volcano in Hawaii. At the northeastern dike, we attribute segmentation to local rotation of the direction of least principal compressive stress. \r\n\r\nFrom continuum-mechanical models of magma and heat flow in idealized conduits, we conclude that magma flows far more rapidly and with less relative heat loss in plugs than in dikes. Although dikes are the preferred form for emplacement, plugs are the preferred form for the flow of magma. We present a numerical solution for volumetric flow rate and wall heat flux for the northeastern dike and find that although the flow rate is extremely sensitive to conduit geometry, the rate of heat loss to wall rocks is not. During emplacement of the northeastern dike, local flow rate increased where wall rocks were eroded and reached a maximum of about 45 times the mean initial rate, whereas the maximum rate of heat loss to wallrocks increased to only 1.6 times the mean initial rate. An inferred progression from continuous magma flow along a dike to flow from a plug agrees well with observations of volcanic eruptions that begin from fissures and later are localized at discrete vents.

The findings were to be submitted for inclusion in an Environmental Impact Statement being assembled by Land Management Services of Jackson, Wyoming. The study area is being considered for possible drilling sites in the near future.
The project area lies on the southwest slope of the Gros Ventre Mountain Range in the Cache Creek-Little Granite Creek area in Teton County, north-western Wyoming. A total of 16 prehistoric sites and isolated finds were recorded within or immediately adjacent to the study area boundaries. The total surface area covered amounted to 1857 acres (or 5.7%) of the 32,580 acres included in the study. An intensive surface evaluation was completed of all staked projects (well locations and access roads) in the survey area. Exploratory or evaluative testing is recommended for the Getty Reserve well location and in one area on the NCRA well access route. Some form of further evaluation is recommended at thirteen other localities.
Fieldwork was conducted during September, 1980, by archeologists from Archeological Services. Subsequent analysis included the application of a model of site predictability based on the statistical analysis of environmental factors, such as slope, aspect, vegetation, soils, fauna and proximity to water.

revision of Outer Continental Shelf oil and gas activities in the Gulf of Mexico and their onshore impacts: A summary report, September 1980","docAbstract":"The Gulf of Mexico Outer Continental Shelf (OCS) continues to be the most intensively developed offshore oil- and gas-producing region in the world. With the development of technology, exploration, development, and production are being extended to include areas off the coast of southwest Florida and deep-water areas near the Mississippi River Delta. Development in both areas requires careful analyses of local considerations. The hydrocarbon potential of the region, while not well established in the frontier portions, generally remains favorable. A total of 482 fields have been discovered to date in the federally regulated part of the Gulf of Mexico. Reserve estimates have been made for the 435 producing fields in the region. Through December 31, 1980, those fields have produced 5.0 billion barrels of oil and condensate, and 48.7 trillion cubic feet of gas. Remaining recoverable reserves are 3.1 billion barrels of oil and 40.2 trillion cubic feet of gas. Estimates of undiscovered recoverable resources for the Gulf of Mexico are 6.6 billion barrels of oil and 71.9 trillion cubic feet of gas.
Since enactment of the Outer Continental Shelf Lands Act in 1953, there have been 42 oil and gas lease sales in the Gulf of Mexico. An average of three lease sales per year are scheduled through 1986. Since 1953, the Bureau of Land Management (BLM) has leased 3,119 tracts in the Gulf of Mexico; 1,825 leases are currently active. The distribution of leased tracts exhibits a regionwide pattern as shown by Lease Sales A62, 62, A66, and 66. Proposed Lease Sales 67, 69, 72, and 74 will probably continue that pattern. Tracts off the coast of southwest Florida in the Charlotte Harbor, Howell Hook, and Pulley Ridge Areas will be offered in upcoming sales. Operations on tracts in deepwater areas slated for future sales may require additional technology.
Exploration, development, and production in the Gulf of Mexico Region are continuing at a rapid pace throughout the Gulf of Mexico. Between January 1, 1980, and April 15, 1981, 197 initial plans of exploration and 165 supplemental plans of exploration were submitted to the U.S. Geological Survey (USGS). During the same period, 107 initial and 131 supplemental plans of development/production were submitted to the USGS. As of May 1981, there were 121 offshore mobile drilling units operating in the Gulf of Mexico.
Pipelines continue to be the preferred mode of transport for Gulf of Mexico OCS oil and gas production. Pipeline additions to the existing network average 69 miles (111 km) per month. At any given time, numerous pipeline projects are under way in the Gulf of Mexico. To supplement OCS oil and gas production several deepwater port projects, designed to handle imported crude oil, are being planned or constructed in the region. The process of transportation planning in the Gulf of Mexico is done by industry and government through BLM's Intergovernmental Planning Program and its Regional Technical Working Group (RTWG). The RTWG has completed the First Edition Gulf of Mexico Regional Transportation Management Plan.
The nearshore and onshore facilities in the Gulf of Mexico service both the domestic onshore and offshore oil and gas industry as well as the global market. Most of the major centers along the Gulf Coast, including Houston, Corpus Christi, Galveston, Beaumont, Port Arthur, and Freeport, Texas; New Orleans, Lake Charles, Lafayette, Baton Rouge, Morgan City, and Houma, Louisiana; Pascagoula, Mississippi; Mobile, Alabama; and Port Manatee, Florida, have ties to the offshore industry. A wide array of services and support industries, ranging from small independent vendors to major international manufacturing contractors, can be found within the region. Profiles of selected centers reveal typical industries and patterns of activity that are characteristic throughout the Gulf Coast region.

Well yields from the aquifer commonly are from 1,000 to 2,000 gallons per minute. Flow toward the main area of pumping stress is eastward from the Cache River and westward from the St. Francis River. The Memphis aquifer acts as a conduit through Crowleys Ridge for induced flow from the St. Francis River basin to the Cache River basn. Water use from the alluvial aquifer since the early 1900 's has been mostly for rice irrigation. Total pumpage for rice in 1978 was about 1,650 ,000 acre-feet, of which about 88 percent was pumped from the aquifer west of Crowleys Ridge. Water levels in wells west of the ridge in parts of Poinsett, Cross, and Craighead Counties in 1978 were 75 feet below land surface and declining about 2 feet per year. Digital-model analysis indicated that at the end of 1978 water was being removed from aquifer storage at the rate of 540,000 acre-feet per year, and streamflow, mostly from the Cache River and Bayou DeView, was being captured at the rate of 430,000 acre-feet per year. Projecting the 1978 pumping rate of 1,460,000 acre-feet per year, the pumping rate would have to be reduced by about 110,000 acre-feet per year by 1990 to sustain sufficient aquifer saturation for water needs through the year 2000 in all parts of Poinsett, Craighead, and Cross Counties west of Crowleys Ridge.

These hazards include areas of rapid accumulation of unconsolidated sediment, areas of intense erosional activity, and regions of submarine sliding and slumping; shallow faults are also being identified and classified.
The region of concern in this report is the continental shelf of the Northeast Gulf of Alaska, between Montague Island (longitude 148° W.) and Icy Bay (longitude 141° W.), figs. 2 and 3. During 1975, nearly 350 bottom grab samples were collected from this region by the Fisheries Research Ship Townsend Cromwell. These samples formed the basis for the initial characterization of the surface deposits.
Four major sedimentary units were defined on the basis of the bottom grab samples and seismic data (fig. 1) (Carlson and Molnia, 1977; Molnia and Carlson, 1978). These units are (1) Holocene glacial—marine sediments (normal marine deposition), (2) Holocene morainal deposits, (3) Quaternary glacial—marine sediments, and (4) Pleistocene and older lithified sediments. Each of these sedimentary units is in turn composed of various facies defined by lithological, structural, and biological parameters (Molnia and Carlson, 1980).
As part of the Northeast Gulf of Alaska project, I am examining the ostracode assemblages occurring in the Cromwell bottom grab samples. This report provides a tabulation of the fauna and flora contained in 102 selected bottom grab samples (figs. 2 and 3). A baseline datum is being established of the environmental factors that significantly control or contribute to the distributional patterns of modern ostracode species occurring in the Gulf of Alaska. The ostracode biofacies defined by characteristic assemblages of species, together with information on the sedimentary facies, provides a model of the environments presently occurring in the Gulf of Alaska, (Brouwers, 1981). This model forms a vital basis for the interpretation of Neogene and Quaternary glaciomarine environments in the Gulf of Alaska Tertiary Province.

The probability of spill occurrences, likely movement of oil slicks, and locations of resources vulnerable to spilled oil were analyzed. The model predicted movement of the center of spill mass and estimated the times between spill occurrence and contact with various resources, to allow a qualitative assessment of oil characteristics at the time of contact; no direct computation was made of weathering and cleanup. The model also assumed that any oil spilled under ice would remain in place, unchanged, until spring breakup. Ice movements, or travel of oil under ice, if occurring, would affect the results in a manner not directly predictable at this time. The combined results of spill occurrence and spill movement predictions yielded estimates of the overall risks associated with development of the proposed lease area. Assuming that oil exists in the lease area (a 99.3-percent chance) it is estimated that the leasing of the tracts proposed for OCS Sale 71 will result in an expected 9.2 oilspills (of 1,000 barrels or larger) over the lease lifetime of 25 years. This estimate is based on historic oilspill accident data for platforms and pipelines on the U.S. OCS (Gulf of Mexico and California). The estimated probability that land will be contacted by one or more oilspills (of 1,000 barrels or larger) that have been at sea less than 30 days (not counting any time trapped under ice) is greater than 99.5 percent. If oilspill accident data for Prudhoe Bay, Alaska, is used in the analysis, it is estimated that 5.6 oilspills (1,000 barrels or larger) will occur over the lease lifetime. The estimated probability that one or more oilspills (1,000 barrels or larger)will occur and contact land is99 percent. The results of a recent experimental cleanup operation for oilspills under ice in Canadian Arctic waters showed a substantial degree of success; this should be considered in evaluating impacts of spills predicted by this model. Oilspill occurrence probabilities are high primarily because of the large amount of oil believed to be present in the area.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr8213","usgsCitation":"Samuels, W., Hopkins, D., and Lanfear, K., 1981, An oilspill risk analysis for the Beaufort Sea, Alaska (proposed sale 71)outer continental shelf lease area: U.S. Geological Survey Open-File Report 82-13, viii, 111 p., ill., maps ;28 cm., https://doi.org/10.3133/ofr8213.","productDescription":"viii, 111 p., ill., maps ;28 cm.","costCenters":[],"links":[{"id":143321,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0013/report-thumb.jpg"},{"id":38734,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0013/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad6e4b07f02db684199","contributors":{"authors":[{"text":"Samuels, W.B.","contributorId":85958,"corporation":false,"usgs":true,"family":"Samuels","given":"W.B.","email":"","affiliations":[],"preferred":false,"id":162281,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hopkins, Dorothy","contributorId":11614,"corporation":false,"usgs":true,"family":"Hopkins","given":"Dorothy","email":"","affiliations":[],"preferred":false,"id":162279,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lanfear, K.J.","contributorId":14392,"corporation":false,"usgs":true,"family":"Lanfear","given":"K.J.","affiliations":[],"preferred":false,"id":162280,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":11722,"text":"ofr81479 - 1981 - Documentation of a dissolved-solids model of the Tongue River, southeastern Montana","interactions":[],"lastModifiedDate":"2012-02-02T00:06:30","indexId":"ofr81479","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1981","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"81-479","title":"Documentation of a dissolved-solids model of the Tongue River, southeastern Montana","docAbstract":"A model has been developed for assessing potential increases in dissolved solids of the Tongue River as a result of leaching of overburden materials used to backfill pits in surface coal-mining operations.

Maps were prepared showing average precipitation, average streamflow, stream temperature, ground- and surface-water quality, sediment yield, and geology. Recommendations were made for additional study and suggested approaches for continued monitoring in the coalfields areas.
moDuring the 1931-75 water years, the minimum discharges for the five major streams that head in the area ranged from about 12,000 to 26,000 acre-feet per year, and the maximum discharges ranged from about 59,000 to 315,000 acre-feet per year. Correlations indicate that 3 years of low-flow records at stream sites in the Wasatch Plateau would allow the development of relationships with long-term sites that can be used to estimate future low-flow records within a standard error of about 20 percent.
Most water-quality degradation in streams occurs along the flanks of the Wasatch Plateau and Book Cliffs. In the uplands, dissolved-solids concentrations generally ranged from less than 100 to about 250 milligrams per liter, and in the lowlands, the concentrations ranged from about 250 to more than 6,000 milligrams per liter.
Most springs in the Wasatch Plateau and Book Cliffs discharge from the Star Point Sandstone or younger formations, and the water generally contains less than about 1,000 milligrams per liter of dissolved solids. The discharges of 65 springs ranged from about 0.2 to 200 gallons per minute. The Blackhawk Formation, which is the principal coal-bearing formation, produces water in many of the mines. The dissolved-solids concentration in water discharging from springs and mines in the Blackhawk ranged from about 60 to 800 milligrams per liter.
In the lowland areas, the Ferron Sandstone Member of the Maneos Shale appears to have the most potential for subsurface development of water of suitable chemical quality for human consumption. Three wells in the Ferron yielded water with dissolved-solids concentrations ranging from about 650 to 1,230 milligrams per liter.
