The United States produced in 1980 about 54 million tons of phosphate rock, which was 40 percent of the world production. About 62 percent of this production was exported, 28 percent as phosphate rock and 34 percent is manufactured fertilizers and chemicals. The remainder was used domestically, largely (88 percent) for fertilizer and animal feed supplement to produce agricultural products (U.S. Bureau of Mines, 1981). A significant portion of these agricultural products was exported, so the phosphate rock that went into that portion was exported indirectly. Thus, most phosphate production is exported directly or indirectly and contributes to the U.S. balance of international payments. Although the marketable value of the phosphate rock produced in 1980 was only about $1.2 billion, the total value of the agricultural and chemical products depending on phosphate rock input is many times that. The continued ability of the U.S. phosphate industry to supply low-cost phosphate rock for export and domestic consumption is clearly of major importance to the Nation.

Montana to provide a base for development, calibration, and verification of a precipitation-runoff model. The study area and data-collection stations within the area are shown on a map. A summary of data collected at each station during the first year, beginning in October 1978, is provided in tables. The data include precipitation, snow depth and water content, air temperature, relative humidity, wind run, solar radiation, soil temperature and moisture, stream discharge, chemical analyses of water, and sediment content.

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.

These changes are attributed here to agricultural, municipal, and industrial water use.
Although water-resource development varied temporally throughout the basin, the history of development along the Platte River and tributaries followed four stages: (1) Construction of small, crude ditches to irrigate flood plains; (2) construction of larger canals to irrigate bench lands; (3) construction of reservoirs to store snowmelt runoff; and (4) accelerated development of ground-water resources. Despite differences in rates of development, diversion and storage of water for irrigation, municipal, and industrial use have changed streamflow patterns throughout the basin. At some stations, significant changes in flood peaks, annual mean discharges, and shapes of flow-duration curves have been recorded.
Changes in streamflow patterns are manifested by changes in appearance of channels of the Platte River. Prior to water development in the 19th century, the Platte was a wide (-2 kilometers), shallow (1.8 to 2.4 meters) river characterized by bankfull spring flows and low summer flows. Although timber generally was scarce in the valley, the Platte channels contained hundreds of small, timbered islands. Since development, the channels have changed radically. Comparing surveyor's maps (General Land Office), drawn during the 1860's, with six sets of aerial photographs, taken between 1938 and 1979, for six 5-kilometer reaches of the river shows that the channels have narrowed considerably above the confluence with the Loup River. The width of the channels in 1979 ranged from 8 to 50 percent of the channel width in 1860. Below the confluence with the Loup River, the width of the river in 1979 was about 92 percent of the channel width in 1860. Above the confluence with the Loup River, width reduction has occurred by progressive encroachment of vegetation and consequent vertical and horizontal accretion on sand bars in the channel. Vegetative encroachment on sand bars has occurred because (1) the present hydrologic regime provides more favorable conditions for germination and growth on sand bars, and (2) since development of the basin, flood peaks are no longer capable of scouring vegetation from the sand bars. Overbank flows evidently have become more common, probably because channel narrowing and vegetative encroachment have increased the hydraulic roughness of the channels. Moreover, the magnitude of low flows has increased and the days of no flows has decreased giving the channels a more perennial character.

For this investigation, the formations considered to be part of the Floridan aquifer are: Lake City and Avon Park Limestones of middle Eocene age; Ocala Limestone of late Eocene age; Suwannee Limestone of Oligocene age; and permeable parts of the Tampa Limestone and Hawthorn Formation of Miocene age that are in hydrologic contact with the rest of the aquifer.

This report is one of a series presenting hydrologic information of the High Plains aquifer in Oklahoma.\r\nThis report consists of two maps showing the altitude and configuration of the eroded pre-Ogallala bedrock surface (sheets 1 and 2) that forms the base of the aquifer. Bedrock slopes generally from west to east and is composed of rocks of Permian, Triassic-Jurassic, and Cretaceous age. The subcrop extent of these rocks is shown by Morton (1973) for Oklahoma and by Weeks and Gutentag (1981) for the entire High Plains study area. Altitudes of the aquifer base were determined from drillers' logs provided by the Oklahoma Water Resources Board and from published and unpublished information in the files of the U.S. Geological Survey. Where data were sparse, the total well depth was used as the aquifer base under the assumption that wells generally are not drilled very deep into non-water yielding bedrock.","language":"ENGLISH","doi":"10.3133/ofr811117","usgsCitation":"Havens, J., 1981, Generalized altitude and configuration of the base of the High Plains regional aquifer, northwestern Oklahoma (WRI/OFR): U.S. Geological Survey Open-File Report 81-1117, 2 maps ;73 x 31 cm. and 23 x 108 cm. folded in envelope 31 x 23 cm., https://doi.org/10.3133/ofr811117.","productDescription":"2 maps ;73 x 31 cm. and 23 x 108 cm. folded in envelope 31 x 23 cm.","costCenters":[],"links":[{"id":168271,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":20275,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1981/1117/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":20276,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1981/1117/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}}],"edition":"WRI/OFR","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b27e4b07f02db6b066f","contributors":{"authors":[{"text":"Havens, John S.","contributorId":13949,"corporation":false,"usgs":true,"family":"Havens","given":"John S.","affiliations":[],"preferred":false,"id":234871,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":46564,"text":"ofr81753 - 1981 - Map showing distribution of Ag, Au, and As in heavy-mineral concentrates from the Golden Trout Wilderness, California","interactions":[],"lastModifiedDate":"2021-12-06T21:00:16.017463","indexId":"ofr81753","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":"81-753","title":"Map showing distribution of Ag, Au, and As in heavy-mineral concentrates from the Golden Trout Wilderness, California","docAbstract":"No abstract available.
