The data were collected by the U.S. Geological Survey in cooperation with the Prairie Island Indian Community. Seventeen monitoring wells were installed by the U.S. Geological Survey in 1998. Fifteen of the wells were installed with the screen at the water-table. The well screens for the other two wells were approximately 26 and 56 feet below the water table. Samples were collected from the wells in 1998. The water-quality properties and constituents determined for the 17 wells include temperature, pH, specific conductance, dissolved oxygen, alkalinity, major ions, nutrients, and iron and manganese. Water samples collected from two of the wells were analyzed for common agricultural pesticides. In addition, semiquantitative immunoassay screens for presence of atrazine and related triazine herbicides were conducted on samples from all 17 wells. Water-surface altitudes were measured during 1999 in the 17 wells and at 8 surface-water sites.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Mounds View, MN","doi":"10.3133/ofr200078","issn":"0094-9140","collaboration":"Prepared in cooperation with the Prairie Island Indian Community","usgsCitation":"Winterstein, T.A., 2000, Water-quality data collected on Prairie Island near Welch, Minnesota, 1998-99: U.S. Geological Survey Open-File Report 2000-78, iv, 25 p., https://doi.org/10.3133/ofr200078.","productDescription":"iv, 25 p.","onlineOnly":"N","additionalOnlineFiles":"N","temporalStart":"1998-01-01","temporalEnd":"1999-12-31","costCenters":[{"id":392,"text":"Minnesota Water Science Center","active":true,"usgs":true}],"links":[{"id":157253,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2000/0078/report-thumb.jpg"},{"id":12219,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://mn.water.usgs.gov/publications/pubs/00-78.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":53878,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2000/0078/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Minnesota","otherGeospatial":"Prairie Island","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -92.75,44.61666666666667 ], [ -92.75,44.7 ], [ -92.61666666666666,44.7 ], [ -92.61666666666666,44.61666666666667 ], [ -92.75,44.61666666666667 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49f2e4b07f02db5eecf2","contributors":{"authors":[{"text":"Winterstein, Thomas A.","contributorId":25971,"corporation":false,"usgs":true,"family":"Winterstein","given":"Thomas","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":192748,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The maps show the locations, ages, and activity rates of major earthquake-related features such as faults and fault-related folds. They are accompanied by databases that describe these features and document current information on their activity in the Quaternary.

The sites are all located within 5 nautical miles of shore on insular shelves or slopes. Regional maps were required of areas much larger than the disposal sites themselves to assess both the regional seafloor geology and the immediate vicinity of the disposal sites. The purpose of the disposal site surveys was to delimit the extent of disposal material by producing detailed bathymetric and backscatter maps of the seafloor with a ± 1 m spatial accuracy and <1% depth error. The advantage of using multibeam over conventional towed, single-beam sidescan sonar is that the multibeam data are accurately georeferenced for precise location of all imaged features. The multibeam produces a coregistered acoustic-backscatter map that is often required to locate individual disposal deposits. These data were collected by the USGS as part of its regional seafloor mapping and in support of ocean disposal site monitoring studies conducted in cooperation with the US Environmental Protection Agency (EPA) and the US Army Corps of Engineers (COE).","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr00124","usgsCitation":"Torresan, M.E., and Gardner, J.V., 2000, Acoustic mapping of the regional seafloor geology in and around Hawaiian ocean dredged-material disposal sites: U.S. Geological Survey Open-File Report 2000-124, HTML document, https://doi.org/10.3133/ofr00124.","productDescription":"HTML document","onlineOnly":"Y","costCenters":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":60341,"rank":3,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/of/2000/0124/summary.html","linkFileType":{"id":1,"text":"pdf"}},{"id":161274,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2000/0124/report-thumb.jpg"},{"id":3308,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2000/0124/","linkFileType":{"id":5,"text":"html"}},{"id":466237,"rank":7,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_25600.htm","text":"Hilo area","linkFileType":{"id":5,"text":"html"}},{"id":466236,"rank":6,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_25599.htm","text":"Maui","linkFileType":{"id":5,"text":"html"}},{"id":466235,"rank":5,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_25598.htm","text":"Oahu","linkFileType":{"id":5,"text":"html"}},{"id":466234,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_25597.htm","text":"Kauai","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Hawai'i","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -178.31,18.91 ], [ -178.31,28.4 ], [ -154.81,28.4 ], [ -154.81,18.91 ], [ -178.31,18.91 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b13e4b07f02db6a34ed","contributors":{"authors":[{"text":"Torresan, Michael E. mtorresan@usgs.gov","contributorId":4392,"corporation":false,"usgs":true,"family":"Torresan","given":"Michael","email":"mtorresan@usgs.gov","middleInitial":"E.","affiliations":[],"preferred":true,"id":208261,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gardner, James V.","contributorId":93035,"corporation":false,"usgs":true,"family":"Gardner","given":"James","email":"","middleInitial":"V.","affiliations":[],"preferred":false,"id":208262,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Therefore, this study seeks to identify the apparent prospective areas for CBM exploration in the Wilcox Group (Paleocene-Eocene) lignite and coalbeds by mapping net coal thickness, depth to coal, and coal rank (vitrinite reflectance). Economic factors are not considered in this CBM prospects study.

Past gold production has come from the Kenai Peninsula and the Girdwood, Port Wells, and Valdez areas. Copper and by-product gold and silver have been produced from mines at Ellamar, on Latouche Island, and near Valdez. Many of the past-producing properties were not mined out and contain significant inferred reserves of gold, copper, lead, zinc, and silver. This report outlines mineral resource areas (tracts) that contain both identified and undiscovered mineral resources. These tracts were drawn on the basis of one or more of the following criteria: (1) geochemical anomalies, (2) favorable geologic units, (3) presence of mines, prospects or mineral occurrences, and (4) geophysical anomalies. Bliss (1989) used six mineral deposit models to describe the types of deposits known from the CNF. Of these deposit types, only four are sufficiently known and defined in the CNF to be suitable for consideration in outlining and ranking of mineral resource tracts; these deposit types are: (1) Cyprus-type massive sulfide, (2) Chugach-type low-sulfide goldquartz veins, (3) placer gold, and (4) polymetallic vein.</p>\n<br/>\n<p>The U.S. Bureau of Mines indicated that most of the inferred mineral reserves in the CNF would not be economic to produce under current prices.

Mine waste and tailings in the unnamed tributary to Jack Creek draining the Bullion mine area and in Uncle Sam Gulch below the Crystal mine are contributors to water quality degradation of Basin Creek and Cataract Creek, Montana. Basin Creek and Cataract Creek are two of three tributaries to the Boulder River in the study area. The bed sediment geochemistry in these two creeks has also been affected by the acidic drainage from these two mines. Geochemical analysis of 42 tailings cores and eleven bed-sediment samples was undertaken to determine the concentrations of Ag, As, Cd, Cu, Pb, and Zn present in these materials. These elements are environmentally significant, in that they can be toxic to fish and/or the invertebrate organisms in the aquatic food chain. Suites of one-inch cores of mine waste and tailings material were taken from two breached tailings impoundments near the site of the Bullion mine and from Uncle Sam Gulch below the Crystal mine. Forty-two core samples were taken and divided into 211 subsamples. The samples were analyzed by ICP-AES (inductively coupled plasma-atomic emission spectroscopy) using a mixed-acid (HC1-HNO<sub>3</sub>-HC1O<sub>4</sub>-HF) digestion. Results of the core analyses show that some samples contain moderate to very high concentrations of arsenic (as much as 13,000 ppm), silver (as much as 130 ppm), cadmium (as much as 260 ppm), copper (as much as 9,000 ppm), lead (as much as 11,000 ppm), and zinc (as much as 18,000 ppm). Eleven bed-sediment samples were also subjected to the mixed-acid total digestion, and a warm (50°C) 2M HC1-1% H<sub>2</sub>O<sub>2</sub> leach and analyzed by ICP-AES. Results indicate that bed sediments of the Jack Creek tributary are impacted by past mining at the Bullion and Crystal mines. The contaminating metals are mostly contained in the 2M HC1-1% H<sub>2</sub>O<sub>2</sub> leachable phase, which are the hydrous amorphous iron- and manganese-hydroxide coatings on detrital sediment particles.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr0031","issn":"0094-9140","usgsCitation":"Fey, D.L., Church, S.E., and

The watershed database includes watersheds delineated to all 1:24,000-scale mapped stream confluences and other hydrologically significant points, selected watershed characteristics, and hydrologic derivative datasets.\r\n\r\nComputer technology allows generation of preliminary watershed boundaries in a fraction of the time needed for manual methods. This automated process reduces development time and results in quality improvements in watershed boundaries and characteristics. These data can then be compiled in a permanent database, eliminating the time-consuming step of data creation at the beginning of a project and providing a stable base dataset that can give users greater confidence when further subdividing watersheds.\r\n\r\nA standardized dataset of watershed characteristics is a valuable contribution to the understanding and management of natural resources. Vertical integration of the input datasets used to automatically generate watershed boundaries is crucial to the success of such an effort. The optimum situation would be to use the digital orthophoto quadrangles as the source of all the input datasets. While the hydrographic data from the digital line graphs can be revised to match the digital orthophoto quadrangles, hypsography data cannot be revised to match the digital orthophoto quadrangles. Revised hydrography from the digital orthophoto quadrangle should be used to create an updated digital elevation model that incorporates the stream channels as revised from the digital orthophoto quadrangle. Computer-generated, standardized watersheds that are vertically integrated with existing digital line graph hydrographic data will continue to be difficult to create until revisions can be made to existing source datasets. Until such time, manual editing will be necessary to make adjustments for man-made features and changes in the natural landscape that are not reflected in the digital elevation model data.","language":"ENGLISH","publisher":"U.S. Dept. of the Interior, U.S. Geological Survey ;\r\nBranch of Information Services [distributor],","doi":"10.3133/ofr0065","issn":"0094-9140","usgsCitation":"Brown, J.R., Ulery, R.L., and Parcher, J.W., 2000, Creating a standardized watersheds database for the lower Rio Grande/Rio Bravo, Texas: U.S. Geological Survey Open-File Report 2000-65, iii, 17 p. :ill., maps ;28 cm., https://doi.org/10.3133/ofr0065.","productDescription":"iii, 17 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":154435,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":1359,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/ofr00-065","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad5e4b07f02db68342e","contributors":{"authors":[{"text":"Brown, Julie R.","contributorId":39816,"corporation":false,"usgs":true,"family":"Brown","given":"Julie","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":188517,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ulery, Randy L. rlulery@usgs.gov","contributorId":4679,"corporation":false,"usgs":true,"family":"Ulery","given":"Randy","email":"rlulery@usgs.gov","middleInitial":"L.","affiliations":[],"preferred":true,"id":188516,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Parcher, Jean W. jwparcher@usgs.gov","contributorId":2209,"corporation":false,"usgs":true,"family":"Parcher","given":"Jean","email":"jwparcher@usgs.gov","middleInitial":"W.","affiliations":[],"preferred":true,"id":188515,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Annual loads were estimated by use of the U.S. Geological Survey ESTIMATOR model and are available upon request. Trends were estimated by use of either linear regression, Seasonal Kendall, or Kendall-Theil tests. Trends were reported for monthly-mean flow, monthly load, flow-adjusted concentration, and flow-weighted concentration. Mean yields and median concentrations were calculated to help assess current water-quality status and to facilitate comparisons between basins. The trend in flow was upward at 12 of the 30 sites. Trends of nutrient and sediment load were upward at these same 12 sites. Trends in flow-adjusted and flow-weighted concentrations varied by species. Trends in flow-weighted concentrations were generally upward or not significant for the nitrogen species and parallel or not significant for phosphorus species. Trends in flow-adjusted concentrations were downward at nearly all sites for sediment and dissolved solids in the Susquehanna and Potomac River Basins and generally were not significant in the Virginia river basins.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr99451","issn":"0094-9140","usgsCitation":"Langland, M.J., Blomquist, J., Sprague, L.A., and Edwards, R.E., 2000, Trends and status of flow, nutrients, and sediments for selected nontidal sites in the Chesapeake Bay Watershed, 1985-98: U.S. Geological Survey Open-File Report 99-451, iv, 17 p.; Appendices, https://doi.org/10.3133/ofr99451.","productDescription":"iv, 17 p.; Appendices","costCenters":[{"id":532,"text":"Pennsylvania Water Science Center","active":true,"usgs":true}],"links":[{"id":119053,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1999/0451/report-thumb.jpg"},{"id":24581,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1999/0451/","linkFileType":{"id":5,"text":"html"}},{"id":51654,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1999/0451/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Delaware;Maryl;New York;Pennsylvania;Virginia;West Virginia","otherGeospatial":"Susquehanna River Basin;Choptank River Basin;Western Shore River Basin;Patuxent River Basin;Potomac River Basin;Rappahannock River Basin;Mattaponi River Basin;Pamunkey River Basin;James River Basin;Appomattox River Basin","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -81,36.75 ], [ -81,43 ], [ -74,43 ], [ -74,36.75 ], [ -81,36.75 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4affe4b07f02db697c91","contributors":{"authors":[{"text":"Langland, Michael J. 0000-0002-8350-8779 langland@usgs.gov","orcid":"https://orcid.org/0000-0002-8350-8779","contributorId":2347,"corporation":false,"usgs":true,"family":"Langland","given":"Michael","email":"langland@usgs.gov","middleInitial":"J.","affiliations":[{"id":532,"text":"Pennsylvania Water Science Center","active":true,"usgs":true}],"preferred":true,"id":187688,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Blomquist, Joel D. jdblomqu@usgs.gov","contributorId":3774,"corporation":false,"usgs":true,"family":"Blomquist","given":"Joel D.","email":"jdblomqu@usgs.gov","affiliations":[{"id":374,"text":"Maryland Water Science Center","active":true,"usgs":true}],"preferred":false,"id":187689,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Sprague, Lori A. 0000-0003-2832-6662 lsprague@usgs.gov","orcid":"https://orcid.org/0000-0003-2832-6662","contributorId":726,"corporation":false,"usgs":true,"family":"Sprague","given":"Lori","email":"lsprague@usgs.gov","middleInitial":"A.","affiliations":[{"id":509,"text":"Office of the Associate Director for Water","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true},{"id":27111,"text":"National Water Quality Program","active":true,"usgs":true}],"preferred":true,"id":187687,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Edwards, Robert E.","contributorId":69191,"corporation":false,"usgs":true,"family":"Edwards","given":"Robert","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":187690,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

An ecological monitoring program was proposed for these resources. Some of the resources are pristine, while others have been affected by development. Each type of resource has physical (habitat, sediment, and hydrology), chemical, and biological (fish, invertebrates, and algae) characteristics that are monitored in a consistent manner so that change may be detected. Not all aspects of the physical, chemical, and biotic components are monitored at each resource type. Monitoring is focused on those aspects most susceptible to change. Replication and comparison with pristine components are a significant part of the program so that actual change can be determined from natural temporal and spatial
