More than 90 percent of the project activity was directed toward the acquisition and processing of data for more than two thousand rainfall-runoff periods occurring during 1964-74 at the 104 project stations. Storm rainfall data were computed at 5-minute intervals from records of six long-term (about 75 years) National Weather Service Stations. The U.S. Geological Survey mathematical rainfall-runoff model is used to synthesize long-term flood records for about 80 percent of the project stations. Station flood-frequency data are developed, using the log-Pearson Type III distribution with regionalized skew coefficients. Multiple regression analysis is used to define relations between flood-frequency station data for small and large streams and 10 physical and climatological basin characteristics. The analysis indicates the drainage-basin size is the most significant variable. Five regions having distinct flood-peak characteristics are delineated. The developed relations, expressed as equations and nomographs, are considered usable for virtually any site in Georgia where the drainage area is between 0.1 and 20 square miles, and the flow is natural.

Major sources of ground water are the Gosport Sand and Lisbon Formation undifferentiated, the Miocene Series undifferentiated, and alluvium and low terrace deposits. The Miocene, the most productive source of ground water, will yield 0.5 to 1.0 mgd (million gallons per day) per well and is a potential source of larger supplies in most of the county. The quantity of potable water available is governed largely by geologic structures. Average flows of the Tombigbee and Mobile Rivers in the southeast corner of the county are 18,200 and 39,400 mgd. Average runoff originating in the county is about 1,100 mgd or 1 mgd per square mile. Water in aquifers tapped by wells generally contains less than 500 mg/l (milligrams per liter) dissolved solids. The water generally is soft to moderately hard. Water in streams is soft to moderately hard and low in dissolved solids. Estimated water use in 1966 was 43.5 mgd of which 10.9 mgd was ground water and 32.6 mgd was surface water. Lava flows underlie the entire basin, and unconsolidated sedimentary deposits overlie the lavas in the Camas Prairie-Glenwood area and in small areas elsewhere. A spring supplies water to much of the Camas Prairie-Glenwood area through a public system, so not many wells are used now. About 56 million gallons (110 acre-feet) of ground water was used in 1974. The unconsolidated deposits yield from 1 to 500 gallons per minute of water to wells, and the basalt can yield more than 100 gallons per minute and possibly several thousand gallons per minute to deep wells. Ground-water recharge and discharge on the reservation is estimated to average 550,000 acre-feet per year.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr75518","usgsCitation":"Cline, D.R., 1976, Reconnaissance of the water resources of the upper Klickitat River Basin, Yakima Indian Reservation, Washington: U.S. Geological Survey Open-File Report 75-518, vi, 54 p., https://doi.org/10.3133/ofr75518.","productDescription":"vi, 54 p.","numberOfPages":"59","costCenters":[{"id":622,"text":"Washington Water Science Center","active":true,"usgs":true}],"links":[{"id":146345,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1975/0518/report-thumb.jpg"},{"id":41505,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1975/0518/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":389662,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_15195.htm"}],"country":"United States","state":"Washington","otherGeospatial":"Klickitat River basin, Yakima Indian Reservation","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -121.5,\n              45.85\n            ],\n            [\n              -120.85,\n              45.85\n            ],\n            [\n              -120.85,\n              46.5\n            ],\n            [\n              -121.5,\n              46.5\n            ],\n            [\n              -121.5,\n              45.85\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a62e4b07f02db6368a4","contributors":{"authors":[{"text":"Cline, Denzel R.","contributorId":87910,"corporation":false,"usgs":true,"family":"Cline","given":"Denzel","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":167173,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Simulations of one-lake and multiple-lake systems in vertical sections show that for many hydrogeologic settings, the line (divide) separating local from regional ground-water flow systems is continuous beneath individual lakes. If the divide is continuous, there exists a point along it at which the head is a minimum compared to all other points along the divide. This point of minimum head is always greater than the head represented by lake level, therefore in such a setting there can be no movement of lake water through the lake bed to the ground-water system. In a setting where the divide is not continuous, the lake loses water through part of its bed, but rarely in the littoral zone of the lake.</p><p>Factors that strongly influence the position, shape, and continuity of the flow-system divide beneath lakes are height of the water table on the downslope side of the lake relative to lake level, position and hydraulic conductivity of aquifers within the ground-water reservoir, ratio of horizontal to vertical hydraulic conductivity of the groundwater system, and lake depth.</p>","language":"English","publisher":"U.S. Government Printing Office","publisherLocation":"Washington, D.C.","doi":"10.3133/pp1001","usgsCitation":"Winter, T.C., 1976, Numerical simulation analysis of the interaction of lakes and ground water: U.S. Geological Survey Professional Paper 1001, iv, 45 p., https://doi.org/10.3133/pp1001.","productDescription":"iv, 45 p.","costCenters":[{"id":478,"text":"North Dakota Water Science Center","active":true,"usgs":true},{"id":34685,"text":"Dakota Water Science Center","active":true,"usgs":true}],"links":[{"id":34022,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/pp/1001/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":123992,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/pp/1001/report-thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b23e4b07f02db6adff0","contributors":{"authors":[{"text":"Winter, Thomas C.","contributorId":84736,"corporation":false,"usgs":true,"family":"Winter","given":"Thomas","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":152885,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Temperatures of these fluids ranged from about 250 deg to 700 deg C for various stages and deposits. Most systems boiled. High salinities, shown by halite-bearing inclusions, and boiling, suggested by coexisting gas and liquid-rich inclusions, are considered to be diagnostic of epizonal intrusions which are the most favorable parents for porphyry copper mineralization. Depth of emplacement of many copper-bearing stocks is deduced from fluid inclusions to have been about 6,000 to 10,000 feet (1,800 to 3,000 metres); fluid pressures during mineralization are interpreted generally to be less than 500 bars.\r\n\r\nModerate-salinity (less than about 12 percent) and moderate-temperature <350 deg C) fluids are noted in all porphyry copper deposits and were responsible for the deposition of most copper and molybdenum in deposits, such as Bagdad, Esperanza, Mineral Park, Morenci, Ray, Sierrita, in the Southwestern United States and several in southern British Columbia. However, with only three exceptions, highly saline fluids apparently were present at an early stage and also deposited metals. The relative amounts and economic importance of copper and molybdenum deposited from high- and moderate-salinity fluids varies within the porphyry deposit class.\r\n\r\nThere is compelling geologic and geochemical evidence that chloride is important for transport of metals, but the porphyry coppers stand out as a class associated with fluids of especially high salinity during at least one stage of their formation. Halite cubes in fluid inclusions are an effective, although rough, indicator of those salinities and can be conveniently monitored during petrographic study of thin sections. Thus, fluid inclusions can be used to characterize favorable intrusions, metal anomalies, and caprocks as an additional method of detecting possible disseminated porphyry copper metallization. The presence of halite-bearing inclusions, especially coexisting with gas-rich inclusions, is considered to be a favorable fluid anomaly in the search for porphyry ore.","language":"ENGLISH","publisher":"U.S. Geological Survey","doi":"10.3133/pp907D","usgsCitation":"Nash, J.T., 1976, Fluid-Inclusion Petrology - Data from Porphyry Copper Deposits and Applications to Exploration: U.S. Geological Survey Professional Paper 907, vi, 16 p., https://doi.org/10.3133/pp907D.","productDescription":"vi, 16 p.","costCenters":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"links":[{"id":117830,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/pp/0907d/report-thumb.jpg"},{"id":33424,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/pp/0907d/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -120,30 ], [ -120,42 ], [ -106,42 ], [ -106,30 ], [ -120,30 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49d6e4b07f02db5de7c7","contributors":{"authors":[{"text":"Nash, J.

Measurements of magnetic properties of samples collected along valley margins or from drill holes indicate that the anomaly-producing rocks are mostly Tertiary volcanic flows in Nevada and mostly Cretaceous-Tertiary intrusives in southern New Mexico. Aeromagnetic data were compiled as both observed and residual anomalies from surveys at various flight-line spacings and intervals from ground surface. Theoretical anomalies from known models were analyzed to recover data on depth, width, and magnetization of models and thereby establish reliability of methods used by certain investigators. These methods were then applied to measured anomalies to obtain information about the igneous rock structures that are buried beneath nonmagnetic valley alluvium. Recommendations made for future valley studies include aeromagnetic surveys flown 150 m above ground surface and at 800 m spacing; measurement of magnetic properties from outcrop samples, drill-core samples, and magnetometer logging of uncased drill holes; and use of the interpretation from gravity surveys in the same area.","language":"ENGLISH","publisher":"U.S. Dept. of the Interior, Geological Survey,","doi":"10.3133/ofr76440","usgsCitation":"Bath, G.D., 1976, Interpretation of magnetic surveys in intermontane valleys of Nevada and southern New Mexico: U.S. Geological Survey Open-File Report 76-440, iii, 37 p. :ill. ;28 cm., https://doi.org/10.3133/ofr76440.","productDescription":"iii, 37 p. :ill. ;28 cm.","costCenters":[],"links":[{"id":149885,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1976/0440/report-thumb.jpg"},{"id":46420,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1976/0440/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aafe4b07f02db66d37d","contributors":{"authors":[{"text":"Bath, G.

Diagenetic alteration of framework grains throughout the stratigraphic sequence has produced widespread zeolite cement or phyllosilicate grain coatings and pseudomatrix. Multiple deformation and deep burial of the older Tertiary sequence--the Orca Group, the shale of Haydon Peak, and the Kulthieth and Tokun Formations--caused extensive alteration and grain interpenetration, resulting in low porosity values. Less intense deformation and intermediate depth of burial of the younger Tertiary sequence--the Katalla, Poul Creek, Redwood, and Yakataga Formations--has resulted in a greater range in textural properties. Most sandstone samples in the younger Tertiary sequence are poorly sorted, tightly packed, and have strongly appressed framework grains, but some are less tightly packed and contain less matrix. Soft and mineralogically unstable framework grains have undergone considerable alteration, reducing pore space even in the youngest rocks. \r\n\r\nMeasurements of porosity, permeability, grain density, and sonic velocity of outcrop samples of the younger Tertiary sequence indicate a modest up-section improvement in sandstone reservoir characteristics. Nonetheless porosity and permeability values typically are below 16 percent and 15 millidarcies respectively and grain densities are consistently high, about 2.7 gm/cc. Low permeability and porosity values, and high grain densities and sonic velocities appear to be typical of most outcrop areas throughout the onshore Gulf of Alaska Tertiary Province.","language":"ENGLISH","publisher":"U.S. Dept. of the Interior, Geological Survey,","doi":"10.3133/ofr76198","usgsCitation":"Winkler, G., McLean, H., and Plafker, G., 1976, Textural and mineralogical study of sandstones from the onshore Gulf of Alaska Tertiary Province, southern Alaska: U.S. Geological Survey Open-File Report 76-198, iii, 48 leaves :ill., map ;27 cm.; (51 p., 6 sheets - PGS), https://doi.org/10.3133/ofr76198.","productDescription":"iii, 48 leaves :ill., map ;27 cm.; (51 p., 6 sheets - PGS)","costCenters":[],"links":[{"id":150179,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1976/0198/report-thumb.jpg"},{"id":45597,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1976/0198/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad5e4b07f02db683737","contributors":{"authors":[{"text":"Winkler, Gary R.","contributorId":75513,"corporation":false,"usgs":true,"family":"Winkler","given":"Gary R.","affiliations":[],"preferred":false,"id":173125,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McLean, Hugh","contributorId":73977,"corporation":false,"usgs":true,"family":"McLean","given":"Hugh","affiliations":[],"preferred":false,"id":173124,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Plafker, George","contributorId":3920,"corporation":false,"usgs":false,"family":"Plafker","given":"George","email":"","affiliations":[],"preferred":false,"id":173123,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The solutions percolate toward the Snake River Plain aquifer (135 m below) through interlayered basalts and unconsolidated sediments and an extensive zone of ground water perched on a sedimentary layer about 40 m beneath the ponds. A three-segment numerical model was developed to simulate the system, including effects of convection, hydrodynamic dispersion, radioactive decay, and adsorption. Simulated hydraulics and solute migration patterns for all segments agree adequately with the available field data. The model can be used to project subsurface distributions of waste solutes under a variety of assumed conditions for the future. Although chloride and tritium reached the aquifer several years ago, the model analysis suggests that the more easily sorbed solutes, such as cesium-137 and strontium-90, would not reach the aquifer in detectable concentrations within 150 years for the conditions assumed.
