Industrial </span><span>and irrigation uses required 73 percent of the freshwater. The largest </span><span>user of freshwater was Hernando County, using 43.0 million gallons per </span><span>day. </span></p><p><span>The ground-water system is comprised of up to three different aquifers--the surficial, the secondary artesian, and the Floridan. Little is known about the surficial and secondary artesian aquifers. </span></p><p><span>The Floridan aquifer consists mostly of limestones and dolomites, and is as much as 1,500 feet thick. Transmissivities are known to be as high as 25 million feet squared per day. Yields of 2,000 gallons per minute from 12-inch wells are possible. Although the range in fluctuations of the potentiometric surface is as great as 20 feet, no significant change has occurred since the 1930's when data were first collected. </span></p><p><span>The quality of water within the Floridan aquifer is generally excellent except near the Gulf Coast and in extreme east Marion County, near the St. Johns River where saltwater is present in the aquifer. Iron and hydrogen sulfide are sometimes a problem, but they can usually be con-trolled by proper well design and aeration of the water. Concentrations of sulfate do not exceed 250 milligrams per liter in the study area, and only in a small part of the area do dissolved-solids concentrations exceed 250 milligrams per liter. </span></p><p><span>Summaries were compiled of more than 1,000 wells, 43 continuous-record gaging stations, 21 lakes, and 46 springs. The predominant chemical type for both streams and springs is calcium and magnesium bicarbonate due to the dissolution process of the carbonate rocks. Along the coastal areas and near the St. Johns River, water is commonly of the sodium chloride type. The majority of the streams have average dissolved-solids concentrations between 100 and 200 milligrams per liter, maximum-observed specific conductance between 250 and 750 micro-mhos per centimeter, and average total nitrogen concentrations of less than 1.2 milligrams per liter. </span></p><p><span>Data for six lakes showed that the range of stage between the 90 and 10 percent exceedance stages is as great as 4.5 feet and as small as 2.2 feet. Little water-quality data for lakes are available, especially for the important constituents such as biochemical oxygen demand, total nitrogen, total phosphorus, and total carbon. </span></p><p><span>Flow-duration data for springs show small ranges in discharge. The differences between the 10 and 90 percent exceedance discharges are 350 cubic feet per second for Silver Springs and 280 cubic feet per second for Rainbow Springs, the two largest springs in the area. Water quality of the springs is relatively constant with time because of the water's long residence time within the carbonate rocks. </span></p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri8111","collaboration":"Prepared in cooperation with the U.S. Army Corps of Engineers","usgsCitation":"Miller, R.A., Anderson, W., Navoy, A.S., Smoot, J.L., and Belles, R.G., 1981, Water-resources information for the Withlacoochee River region, west-central Florida: U.S. Geological Survey Water-Resources Investigations Report 81-11, xi, 130 p., https://doi.org/10.3133/wri8111.","productDescription":"xi, 130 p.","costCenters":[],"links":[{"id":380157,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1981/0011/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":158287,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1981/0011/report-thumb.jpg"}],"country":"United States","state":"Florida","otherGeospatial":"Withlacoochee River region","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -83.5894775390625,\n              28.434883464940082\n            ],\n            [\n              -81.54052734375,\n              28.434883464940082\n            ],\n            [\n              -81.54052734375,\n              29.82158272057499\n            ],\n            [\n              -83.5894775390625,\n              29.82158272057499\n            ],\n            [\n              -83.5894775390625,\n              28.434883464940082\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a08e4b07f02db5f9d16","contributors":{"authors":[{"text":"Miller, Robert A.","contributorId":52938,"corporation":false,"usgs":true,"family":"Miller","given":"Robert","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":195369,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Anderson, Warren","contributorId":7712,"corporation":false,"usgs":true,"family":"Anderson","given":"Warren","affiliations":[],"preferred":false,"id":195367,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Navoy, Anthony S. anavoy@usgs.gov","contributorId":2464,"corporation":false,"usgs":true,"family":"Navoy","given":"Anthony","email":"anavoy@usgs.gov","middleInitial":"S.","affiliations":[],"preferred":true,"id":195365,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Smoot, James L.","contributorId":13605,"corporation":false,"usgs":true,"family":"Smoot","given":"James","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":195368,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Belles, Roger G.","contributorId":6423,"corporation":false,"usgs":true,"family":"Belles","given":"Roger","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":195366,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Interpretation of the geophysical data collected indicated that depth to bedrock below the valley floor varies between about 350 and 450 feet. Two, and perhaps three, major unconsolidated sedimentary layers are inferred to overlie bedrock, although other significant layers may not have been recognizable. No prior subsurface data were available in this area. A resistivity sounding was made also at a site about 7 miles downstream to explore for a buried bedrock channel. The data here indicated that the bedrock surface is about 50 feet above sea level. Hence, the hypothesis of a buried ancient outlet valley of Eagle River at this location gained more credence.

The rocks are Archean in age; they predate a major Precambrian orogeny that affected all of southwestern Montana about 2,750 m.y. ago. The principal bed of iron-formation occurs within a metasedimentary sequence that has dolomite marble at the base and rests on quartzofeldspathic gneiss of uncertain origin. The stratigraphic thickness of the preserved part of the metasedimentary group cannot readily be established because of structural complexities, including both thickening and attenuation, but it probably does not exceed 300 m. The true (original) thickness of the iron-formation is even more difficult to determine because of the structural incompetence of the rock, but it ranges from 15 to 30 m. All the rocks, with the exception of a few younger Precambrian (Proterozoic Y) diabase dikes, are metamorphosed to amphibolite or hornblende granulite facies. The iron-formation typically consists of quartz and magnetite, with subordinate amounts of iron silicates, mainly hypersthene, garnet, clinopyroxene, and grunerite. \r\n\r\nThe principal deposits of iron-formation are in the Copper Mountain area, an area of about 13 km 2 in the west-central part of the Tobacco Root range that has been mapped in some detail. The structure consists of an early set of tight isoclinal folds, trending north-south and overturned to the east, that are deformed by later crossfolds that trend and plunge northwest. The most prominent belt of iron-formation is on a tight anticlinal buckle within the northsouth-trending Ramshorn syncline, a major structure of the first fold set. This belt of iron-formation is estimated to contain about 63 million t of potential low-grade ore (taconite) to a depth of 100 m. The rock contains about 35 weight percent Fe, mostly in the form of magnetite. \r\n\r\nIron-formation occurs in many other localities in the region as distinctive but thin and discontinuous units. Some deposits probably are stratigraphically equivalent to the iron-formation of the Copper Mountain area, but others have quite different lithologic associations and probably different ages.","language":"ENGLISH","doi":"10.3133/pp1187","usgsCitation":"James, H.L., 1981, Bedded Precambrian iron deposits of the Tobacco Root Mountains, southwestern Montana: U.S. Geological Survey Professional Paper 1187, 16 p.; 1 plate in pocket, https://doi.org/10.3133/pp1187.","productDescription":"16 p.; 1 plate in pocket","costCenters":[],"links":[{"id":124323,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/pp/1187/report-thumb.jpg"},{"id":247692,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1187/plate-1.pdf","size":"2573","linkFileType":{"id":1,"text":"pdf"}},{"id":65447,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/pp/1187/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a6be4b07f02db63dc0c","contributors":{"authors":[{"text":"James, H.

The Divide Section, the northernmost 39 miles of the Waterway, will consist, from north to south, of (1) a dredged channel, (2) the Divide Cut, and (3) an artifical lake impounded by the Bay Springs Dam. In all three , water will be at Tennessee River level. A three-dimensional digital model covering 3,273 square miles was constructed to simulate ground-water flow in the Gordo and Eutaw Formations and the Coffee Sand in the vicinity of the Divide Section. The model was calibrated to preconstruction water levels, then used to simulate the effects of stresses imposed by the construction of the Divide Section. The model indicates that the system stabilizes after major changes in conditions within a few months. The Divide Cut acts as a drain, lowering water levels as much as 55 feet. Drawdowns of 5 feet occur as much as 8 miles from the Cut. The 80-foot-high Bay Springs Dam raises ground-water levels by 5 feet as far as 6 miles from its impoundment. Drawdown is not likely to affect public water supplies significantly, but probably will adversely affect a relatively small number of private wells.

Flows in Separation Creek are seasonal and highly variable. Streamflow is primarily caused by snowmelt. Very light snowpack in the spring of 1977 resulted in annual runoff being only 10 percent of that for the previous year. Surface-water quality is variable in both time and space. Dissolved-solids concentrations ranged from less than 100 to more than 1,500 milligrams per liter. Flushing of accumulated salts occurs during a rising stage. Ground water is obtainable from the Mesaverde Formation, the Lance and Fort Union Formations, and from alluvium. Yields from wells and springs are usually less than 10 gallons per minute, though some springs flow as much as 35 gallons per minute. Ground-water quality varies with the formation. Stream biota are governed by the intermittent nature of the stream and by habitat. Daily mean sediment concentrations ranged from 34 to 11,900 milligrams per liter.

About 70 percent of the project funding was used to acquire radar imagery and to evaluate Alaskan applications. Results of these studies indicate that radar images have a unique incremental value for certain geologic and cartographic applications but that the images are best suited for use as supplemental information sources or as primary data sources in areas of persistent cloud cover.</p><p>The value of radar data is greatest for geologic mapping and resource surveys, particularly for mineral and petroleum exploration, where the objective is to locate any single feature or group of features that may control the occurrences of these resources. Radar images are considered by oil and gas companies to be worth the cost of data acquisition within a limited area of active exploration.</p><p>Radar images also have incremental value for geologic site studies and hazard mapping. The need in these cases is TO inventory all geologic hazards to human life, property, resources, and the environment. For other geologic applications, radar images have a relatively small incremental value over a combination of Landsat images and aerial photographs.</p><p>The value of radar images for cartographic applications is minimal, except when they are used as a substitute for aerial photographs and topographic maps in persistently cloud-covered areas. If conventional data sources are not available, radar images provide useful information on terrain relief, landforms, drainage patterns, and land cover. Screen less lithography is a low-cost method of reproducing the images. </p><p>The images from modern, commercially available radar systems have good visual quality; they also have better geometric accuracy and higher information content than images from older systems. Images from modern systems, however, also have some of the same disadvantages as those from older systems. The most serious problem is that considerable information is lost in the process of recording the radar return on film. Another problem is that the oblique radar view of the landscape results in interpretations that are biased by look direction. A compromise antenna depression angle also commonly results in inadequate or excessive shadowing in parts of the image. There is a need for high-resolution digital data, not currently available from the private sector, to significantly improve the utility of radar data for geologic and cartographic applications.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr811358","usgsCitation":"Moore, G.K., and Sheehan, C.A., 1981, Evaluation of radar imagery for geological and cartographic applications: U.S. Geological Survey Open-File Report 81-1358, iii, 37 p., https://doi.org/10.3133/ofr811358.","productDescription":"iii, 37 p.","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":143925,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1981/1358/report-thumb.jpg"},{"id":38225,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1981/1358/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a09e4b07f02db5fac20","contributors":{"authors":[{"text":"Moore, Gerald K.","contributorId":14377,"corporation":false,"usgs":true,"family":"Moore","given":"Gerald","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":161312,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sheehan, Cynthia A.","contributorId":44921,"corporation":false,"usgs":true,"family":"Sheehan","given":"Cynthia","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":161313,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

This study of the hydrology and geochemistry of the area used ground-water solute-transport-modeling techniques to investigate the possible impact of the mines on water quality. Maps of the extent and structure of the aquifer were prepared and show that a saturated thickness of 2,000 feet occurs in the northeast part of the basin. Ground-water recharge in the upland areas in the east, south, and west parts of the basin moves down into deeper zones in the aquifer and laterally to the discharge areas along Piceance and Yellow Creeks. The saline zone and the unsaturated zone provide the majority of the dissolved solids found in the ground water. Precipitation, ion-exchange, and oxidation-reduction reactions are also occuring in the aquifer. Model simulations of ground-water pumpage in tracts C-a and C-b indicate that the altered direction of ground-water movement near the pumped mines will cause an improvement in ground-water quality near the mines and a degradation of water quality downgradient from the tracts. Model simulations of mine leaching in tract C-a and C-b indicate that equal rates of mine leaching in the tracts will produce much different effects on the water quality in the basin. Tract C-a, by virtue of its remote location from perennial streams, will primarily degrade the ground-water quality over a large area to the northeast of the tract. Tract C-b, by contrast, will primarily degrade the surface-water quality in Piceance Creek, with only localized effects on the ground-water quality.
