Sediment cores were extracted from two sites (one shallow and one deep) in Las Vegas Bay, from one site in the Overton Arm, and from one site near the historic confluence of the Colorado and Virgin Rivers. The sediment cores were age-dated using cesium-137 and were analyzed for the presence of organochlorine compounds (pesticides and degradation products, polychlorinated biphenyls, dioxins, and furans) and for semivolatile organic compounds (polycyclic aromatic hydrocarbons and phenols). Sediment-deposition rates after impoundment of the Colorado River by Hoover Dam were determined by measuring the accumulation of mass during three different periods: (1) from the approximate impoundment date for each site (1935-37) to the initial occurrence of cesium-137 in the atmosphere (1952); (2) from 1952 to the maximum concentration of cesium-137 in the atmosphere (1964); and (3) from 1964 to the collection date of the sample (1998). Sediment-deposition rates for the entire post-impoundment period (1935-98) averaged 1.45 (g/cm2)/yr (grams per square centimeter per year) at the Las Vegas Bay shallow site, 1.25 (g/cm2)/yr at the Las Vegas Bay deep site, 0.80 (g/cm2)/yr at the Overton Arm site, and 0.65 (g/cm2)/yr at the Colorado and Virgin Rivers confluence site.\rSediment-deposition rates after impoundment of the Colorado River by Hoover Dam were determined by measuring the accumulation of mass during three different periods: (1) from the approximate impoundment date for each site (1935-37) to the initial occurrence of cesium-137 in the atmosphere (1952); (2) from 1952 to the maximum concentration of cesium-137 in the atmosphere (1964); and (3) from 1964 to the collection date of the sample (1998).

The U.S. Geological Survey designed and operated a streamflow and water quality\nmonitoring network in the basin during the 1999 water year (October 1, 1998, through September 30, 1999) in support of this Remedial Investigation/Feasibility Study. The objective for\nthe network was to quantify the absolute and relative magnitude of hydrologic, trace-element, and nutrient loads transported by numerous stream reaches within the Spokane River Basin. Of the 29 water-quality stations in the network, 19 were in the Coeur d?Alene River Basin, 2 were in the St. Joe River Basin, and the remaining 8 were on the Spokane River downstream from Coeur d'Alene Lake. All stations were sampled for whole-water recoverable and dissolved concentrations of cadmium, lead, and zinc. Nitrogen and phosphorus concentrations were sampled at nine stations to determine loads of nutrients into and out of Coeur d'Alene Lake and transported down the Spokane River into the Columbia River. Mean daily discharge during the 1999 water year was about 120 percent of the long-term average. Trace-element loads to the Columbia River were calculated for the basin's terminal station, Spokane River at Long Lake. For whole-water recoverable cadmium, 2,110 pounds, 92 percent of which was dissolved, was delivered to the Columbia River. The Columbia River received 25,000 pounds of whole-water recoverable lead, 29 percent of which was dissolved, from the Spokane River Basin. The largest trace-element load delivered to the Columbia River by the Spokane River was 764,000 pounds of whole-water recoverable zinc, 76 percent of which was dissolved. The primary source of trace-element loads in the Spokane River Basin was the Coeur d'Alene River Basin. The South Fork Coeur d'Alene River was the largest source of dissolved and wholewater recoverable loads of cadmium and zinc. In contrast, the main stem of the Coeur d'Alene River was the largest source of dissolved and wholewater recoverable loads of lead. Within the South Fork, substantial increases in dissolved loads of cadmium, lead, and zinc were detected in excess of those measured by the monitoring network stations upstream from the terminal station, South Fork Coeur d'Alene River near Pinehurst. Much of the added load was attributed to inflow of traceelement-contaminated ground water. Similarly, increases in whole-water recoverable loads of cadmium, lead, and zinc were detected in the South Fork in excess of measured loads; these were attributed largely to erosion and transport of sediment-associated trace elements during increased stream discharge events. Coeur d'Alene Lake received nearly all its trace-element loads from the Coeur d'Alene River. The lake retained the majority of the dissolved and whole-water recoverable loads of lead input to it, but retained almost none of its dissolved and whole-water recoverable loads of zinc. About one-half of the dissolved and whole-water recoverable loads of cadmium was retained in the lake. Within the Spokane River Basin, the largest loads of total nitrogen, 13,000,000 pounds, and total phosphorus, 677,000 pounds, were measuredat Spokane River at Long Lake, the station closest to the Columbia River. At Coeur d'Alene Lake, total nitrogen loads input to the lake from the Coeur d'Alene and St. Joe Rivers totaled 1,890,000 pounds; the lake discharged 2,430,000 pounds. The lake received 253,000 pounds of total phosphorus and discharged 187,000 pounds; thus, 66,000 pounds was retained by the lake.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr00441","collaboration":"Prepared in cooperation with U.S. Environmental Protection Agency","usgsCitation":"Woods, P.F., 2001, Concentrations and loads of cadmium, lead, zinc, and nutrients measured during the 1999 water year within the Spokane River basin, Idaho and Washington: U.S. Geological Survey Open-File Report 2000-441, iv, 32 p., https://doi.org/10.3133/ofr00441.","productDescription":"iv, 32 p.","numberOfPages":"38","costCenters":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"links":[{"id":262350,"rank":800,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2000/0441/report.pdf"},{"id":262351,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2000/0441/report-thumb.jpg"}],"country":"United States","state":"Idaho","otherGeospatial":"Coeur D'alene River Basin;St. Joe River Basin;Coeur D'alene Lake;Long Lake","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -118.4966,46.753 ], [ -118.4966,47.9947 ], [ -114.9876,47.9947 ], [ -114.9876,46.753 ], [ -118.4966,46.753 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b16e4b07f02db6a55d6","contributors":{"authors":[{"text":"Woods, P.

Dissolved nickel and predominant ligands (represented by dissolved organic carbon, and sulfides) were the solutes of primary interest, although a variety of ancillary measurements were also performed to provide a framework for interpretation. Results described herein integrate information needs identified by the State Water Resources Control Board and local stakeholders with fundamental research associated with the U.S. Geological Survey Toxic Substances Hydrology Program. Dissolved-Ni concentrations in the bottom water over the three sampling dates ranged from 34 to 43 nanomoles per liter. Dissolved-macronutrient concentrations in the bottom water were consistently higher (frequently by orders of magnitude) than surface-water determinations reported for similar times and locations (Regional Monitoring Program, 2001). This is consistent with measured positive benthic fluxes for the macronutrients. Benthic-flux estimates for dissolved nickel from core-incubations, when areally averaged over the South Bay, were significant (that is, of equivalent or greater order of magnitude) relative to previously reported freshwater point and non-point sources. This observation is consistent with previous determinations for other metals, and with the potential remobilization of sediment-associated metals that have been ubiquitously distributed in the South Bay. Similar to dissolved-nickel results, benthic flux of macronutrients was also consistently significant relative to surface-water inputs. These results add to a growing body of knowledge that strongly suggests a need to consider contaminant transport across the sediment-water interface when establishing future management strategies for the watershed.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr0189","usgsCitation":"Topping, B., Kuwabara, J., Parcheso, F., Hager, S., Arnsberg, A., and Murphy, F., 2001, Benthic flux of dissolved nickel into the water column of south San Francisco Bay: U.S. Geological Survey Open-File Report 2001-89, 50 p., https://doi.org/10.3133/ofr0189.","productDescription":"50 p.","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":552,"text":"San Francisco Bay-Delta","active":false,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true},{"id":5079,"text":"Pacific Regional Director's Office","active":true,"usgs":true}],"links":[{"id":2845,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/ofr01-089/index.html","linkFileType":{"id":5,"text":"html"}},{"id":160776,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"San Francisco Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -123.035888671875,\n              37.36142550190517\n            ],\n            [\n              -121.84936523437499,\n              37.36142550190517\n            ],\n            [\n              -121.84936523437499,\n              38.1777509666256\n            ],\n            [\n              -123.035888671875,\n              38.1777509666256\n            ],\n            [\n              -123.035888671875,\n              37.36142550190517\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a53e4b07f02db62b5cd","contributors":{"authors":[{"text":"Topping, B.R.","contributorId":97541,"corporation":false,"usgs":true,"family":"Topping","given":"B.R.","email":"","affiliations":[],"preferred":false,"id":205455,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kuwabara, J.S.","contributorId":57905,"corporation":false,"usgs":true,"family":"Kuwabara","given":"J.S.","email":"","affiliations":[],"preferred":false,"id":205453,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Parcheso, Francis 0000-0002-9471-7787 parchaso@usgs.gov","orcid":"https://orcid.org/0000-0002-9471-7787","contributorId":2590,"corporation":false,"usgs":true,"family":"Parcheso","given":"Francis","email":"parchaso@usgs.gov","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":false,"id":205450,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hager, S.W.","contributorId":51746,"corporation":false,"usgs":true,"family":"Hager","given":"S.W.","email":"","affiliations":[],"preferred":false,"id":205452,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Arnsberg, A.J.","contributorId":92715,"corporation":false,"usgs":true,"family":"Arnsberg","given":"A.J.","email":"","affiliations":[],"preferred":false,"id":205454,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Murphy, Fred fmurphy@usgs.gov","contributorId":4572,"corporation":false,"usgs":true,"family":"Murphy","given":"Fred","email":"fmurphy@usgs.gov","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":205451,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Continuous cores of the\r\nwetland sediment and of the Canal Creek aquifer\r\nwere collected at five sites. Attempts to sample\r\nground water were made by use of a continuous\r\nprofiler at 12 sites, without well installation, at a\r\ntotal of 81 depths within the aquifer. Of those\r\n81 attempts, only 34 sampling depths produced\r\nenough water to collect samples.\r\nGround-water samples from two sites had the\r\nhighest concentrations of volatile organic\r\ncompounds?with total volatile organic\r\ncompound concentrations in the upper part of\r\nthe aquifer ranging from about 15,000 to 50,000\r\nmicrograms per liter. Ground-water samples\r\nfrom five sites had much lower total volatile\r\norganic compound concentrations (95 to 2,100\r\nmicrograms per liter), whereas two sites were\r\nessentially not contaminated, with total volatile\r\norganic compound concentrations less than or\r\nequal to 5 micrograms per liter.","language":"ENGLISH","publisher":"U.S. Dept. of the Interior, U.S. Geological Survey ;\r\nBranch of Information Services [distributor],","doi":"10.3133/ofr00446","issn":"0094-9140","usgsCitation":"Phelan, D.J., Senus, M.P., and Olsen, L., 2001, Lithologic and ground-water-quality data collected using Hoverprobe drilling techniques at the West Branch Canal Creek wetland, Aberdeen Proving Ground, Maryland, April-May 2000: U.S. Geological Survey Open-File Report 2000-446, vii, 43 p. :col. ill., maps ;28 cm., https://doi.org/10.3133/ofr00446.","productDescription":"vii, 43 p. :col. ill., maps ;28 cm.","costCenters":[],"links":[{"id":1578,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2000/ofr00-446/","linkFileType":{"id":5,"text":"html"}},{"id":155467,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0be4b07f02db5fc20b","contributors":{"authors":[{"text":"Phelan, Daniel J.","contributorId":51716,"corporation":false,"usgs":true,"family":"Phelan","given":"Daniel","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":191445,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Senus, Michael P.","contributorId":39820,"corporation":false,"usgs":true,"family":"Senus","given":"Michael","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":191444,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Olsen, Lisa D. ldolsen@usgs.gov","contributorId":2707,"corporation":false,"usgs":true,"family":"Olsen","given":"Lisa D.","email":"ldolsen@usgs.gov","affiliations":[{"id":509,"text":"Office of the Associate Director for Water","active":true,"usgs":true}],"preferred":true,"id":191443,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

At the same time, several of these parks include active and potentially active volcanoes that could pose serious hazards - earthquakes, mudflows, and hydrothermal explosions, as well as eruptions - events that would profoundly affect park visitors, employees, and infrastructure. Although most parks are in relatively remote areas, those with high visitation have daily populations during the peak season equivalent to those of moderate-sized cities. For example, Yellowstone and Grand Teton national parks can have a combined daily population of 80,000 during the summer, with total annual visitation of 7 million. Nearly 3 million people enter Hawai`i Volcanoes National Park every year, where the on-going (since 1983) eruption of Kilauea presents the challenge of keeping visitors out of harm's way while still allowing them to enjoy the volcano's spellbinding activity.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr01435","usgsCitation":"Brantley, S., and McClelland, L., 2001, Volcanism in national parks: summary of the workshop convened by the U.S. Geological Survey and National Park Service, 26-29 September 2000, Redding, California: U.S. Geological Survey Open-File Report 2001-435, Report: PDF, 43 p.; Report: HTML Document, https://doi.org/10.3133/ofr01435.","productDescription":"Report: PDF, 43 p.; Report: HTML Document","numberOfPages":"43","additionalOnlineFiles":"Y","costCenters":[{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true}],"links":[{"id":282915,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":3002,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/0435/","linkFileType":{"id":5,"text":"html"}},{"id":59754,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0435/pdf/of01-435.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":282914,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0435/ofr01-435_report.html"}],"country":"United States","state":"Alaska;California;Hawai'i;Oregon;Washington;Wyoming","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 172.45,32.37 ], [ 172.45,71.39 ], [ -103.89,71.39 ], [ -103.89,32.37 ], [ 172.45,32.37 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0de4b07f02db5fd7e5","contributors":{"editors":[{"text":"Guffanti, Marianne","contributorId":55334,"corporation":false,"usgs":true,"family":"Guffanti","given":"Marianne","affiliations":[],"preferred":false,"id":745714,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Brantley, Steven R. srbrant@usgs.gov","contributorId":4182,"corporation":false,"usgs":true,"family":"Brantley","given":"Steven R.","email":"srbrant@usgs.gov","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":205750,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McClelland, Lindsay","contributorId":51652,"corporation":false,"usgs":true,"family":"McClelland","given":"Lindsay","email":"","affiliations":[],"preferred":false,"id":205751,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The objective of this particular study was to improve our understanding\nof the effects of different river discharges and lake levels of Coeur d'Alene Lake on the transport of cadmium, zinc, and lead within the main stem Coeur d'Alene River. In particular, water-quality data and loads during a broad range of hydrologic conditions were examined to determine if the river channel, flood plain, and associated ground water along the main stem Coeur d'Alene River acted as sources or sinks of trace elements. Water-quality samples were collected at six riverine stations and one lake station along a 35-mile reach during March, June, September, and October of 1999. Samples were analyzed for whole-water recoverable, filtered (0.45 micrometer), and dissolved (0.01 micrometer) concentrations of cadmium, zinc, and lead. Concentrations and loads of cadmium and zinc measured during the four sampling trips were predominately in the filtered and dissolved fraction ,rather than particulate. The smallest concentrations were measured during the June sampling trip when flows were high and snowmelt runoff diluted riverine concentrations. Conversely, the largest concentrations were measured during the latter two sampling trips when flows were low because a larger proportion of the river's discharge was contributed by ground-water inflow. During each sampling trip, cadmium and zinc concentrations generally decreased in a downstream directioeven as discharge increased in a downstream direction. Spatial and temporal trends exhibited by lead concentrations and loads during the four sampling trips were different from those of cadmium and zinc because of the propensity for lead to adsorb to sediment particles. Whole-water recoverable lead concentrations and loads during the four sampling trips were predominantly in the particulate fraction, with filtered and dissolved concentrations and loads composing a much smaller proportion of the recoverable fraction compared to cadmium and zinc. Filtered lead concentrations generally increased at a faster rate in the downstream direction than dissolved lead concentrations; thus, colloidallead either was being formed by complexation reactions or being added by sediment erosion in the downstream direction.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr0134","collaboration":"Prepared in cooperation with U.S. Environmental Protection Agency","usgsCitation":"Woods, P.F., 2001, Concentrations and loads of cadmium, zinc, and lead in the main stem Coeur d'Alene River, Idaho&mdash;March, June, September, and October 1999: U.S. Geological Survey Open-File Report 2001-34, iv, 33 p., https://doi.org/10.3133/ofr0134.","productDescription":"iv, 33 p.","numberOfPages":"39","costCenters":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"links":[{"id":262352,"rank":800,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0034/report.pdf"},{"id":262353,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2001/0034/report-thumb.jpg"}],"country":"United States","state":"Idaho","city":"Coeur D'alene;Cataldo;Harrison","otherGeospatial":"Coeur D'alene Lake;Rose Lake;Post Falls Dam","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -117.0464,47.1971 ], [ -117.0464,47.9819 ], [ -115.995,47.9819 ], [ -115.995,47.1971 ], [ -117.0464,47.1971 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b16e4b07f02db6a5605","contributors":{"authors":[{"text":"Woods, P.

Paleoliquefaction studies have been used extensively in the central and eastern U.S. to assess seismic hazards, and could be used elsewhere to good purpose because paleoliquefaction studies in some field settings can reveal more than other methods, such as fault studies, about the prehistoric strength of shaking and earthquake magnitude. \r\n\r\nWe present guidelines for the conduct of a paleoliquefaction study in continental deposits, mainly in terms of the geologic/seismologic setting and geotechnical properties, because a successful interpretation requires factors from all these disciplines. No single discipline suffices alone. Their interactions must be appreciated in order to understand why seismically induced liquefaction features are found in some locales and not in others. \r\n\r\nThe guidelines that we present also relate to three primary issues for which liquefaction features are especially useful for interpretations: Where was the tectonic source? What was the strength of shaking? And what was the magnitude? In discussing these issues we focus on the following aspects of level-ground liquefaction: (1) mechanisms that form seismic liquefaction features in the field; (2) field settings where liquefaction features should be present if strong seismic shaking has occurred; (3) field settings where an absence of liquefaction features indicates an absence of strong seismic shaking; (4) how liquefaction features should be used to interpret the tectonic source locale of a paleo-earthquake; and (5) how effects of liquefaction can be used to back-calculate the strength of shaking as well as earthquake magnitude. \r\n\r\nSeveral methods are available to back-calculate the strength of shaking and earthquake magnitude, and the most commonly used methods are presented and critiqued. Our critique of these methods points out the uncertainties attending each. Paleoliquefaction/paleoseismic case histories are presented to illustrate potential uncertainties in back-calculations and procedures to overcome these uncertainties. \r\n\r\nReasonable confidence in paleoseismic interpretation generally requires using multiple methods of back-analysis, and achieving similar results from each method. An alternate approach can be used for paleo-earthquakes that were large enough to have caused liquefaction in a variety of geologic settings, in which there were differing factors affecting surface ground motions and liquefaction susceptibility. For this situation, a method such as the cyclic-stress method can be used to make back-calculations that can be cross-checked with results from other settings.","language":"ENGLISH","doi":"10.3133/ofr0129","usgsCitation":"Obermeier, S.F., Pond, E.C., Olson, S.M., Green, R.A., Stark, T., and Mitchell, J.K., 2001, Paleoliquefaction studies in continental setting; geologic and geotechnical factors in interpretations and back-analysis: U.S. Geological Survey Open-File Report 2001-29, 72 p., https://doi.org/10.3133/ofr0129.","productDescription":"72 p.","costCenters":[],"links":[{"id":160332,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":2743,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/openfile/of01-029/ ","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae4e4b07f02db689c53","contributors":{"authors":[{"text":"Obermeier, Stephen F.","contributorId":102482,"corporation":false,"usgs":true,"family":"Obermeier","given":"Stephen","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":205331,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pond, Eric C.","contributorId":82361,"corporation":false,"usgs":true,"family":"Pond","given":"Eric","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":205328,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Olson, Scott M.","contributorId":11257,"corporation":false,"usgs":true,"family":"Olson","given":"Scott","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":205326,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Green, Russell A.","contributorId":94708,"corporation":false,"usgs":false,"family":"Green","given":"Russell","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":205329,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Stark, Timothy D.","contributorId":58317,"corporation":false,"usgs":true,"family":"Stark","given":"Timothy D.","affiliations":[],"preferred":false,"id":205327,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Mitchell, James K.","contributorId":99598,"corporation":false,"usgs":true,"family":"Mitchell","given":"James","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":205330,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Two deltas off the mouth of Las Vegas Wash formed at different lake elevations and account for 41% of the total volume of post-impoundment sediment within the study area. Deltas off the other two washes (Gypsum and Government) account for only 6% of the total volume. The sediment beyond the front of the deltas is primarily mud, and it only occurs in valley floors, where it forms a flat-lying blanket that is mostly less than 1.5 m thick. Although a thin layer, the fine-grained sediment accounts for approximately 53% of the total post-impoundment sediment volume of 5.7 x 106 m3 that has accumulated in the study area.

Classification of areas by type of mining-related activity at active mines is generally detailed; however, the spatial coverage does not differentiate mining-related surface disturbance features at many of the closed or inactive mines.</p>\n<br/>\n<p>Nineteen phosphate mine sites are included in the study. A total of 5,728 hc (14,154 ac), or more than 57 km<sup>2</sup> (22 mi<sup>2</sup>), of phosphate mining-related surface disturbance are documented in the spatial coverage of the core of the southeast Idaho phosphate resource area. The study includes 4 active phosphate mines—Dry Valley, Enoch Valley, Rasmussen Ridge, and Smoky Canyon—and 15 historic phosphate mines—Ballard, Champ, Conda, Diamond Gulch, Gay, Georgetown Canyon, Henry, Home Canyon, Lanes Creek, Maybe Canyon, Mountain Fuel, Trail Canyon, Rattlesnake Canyon, Waterloo, and Wooley Valley. Spatial data on the inactive historic mines is relatively up-to-date; however, spatially described areas for active mines are based on digital maps prepared in early 1999. The inactive Gay mine has the largest total area of disturbance: 1,917 hc (4,736 ac) or about 19 km<sup>2</sup> (7.4 mi<sup>2</sup>). It encompasses over three times the disturbance area of the next largest mine, the Conda mine with 607 hc (1,504 ac), and it is nearly four times the area of the Smoky Canyon mine, the largest of the active mines with 497 hc (1,228 ac).</p>\n<br/>\n<p>The wide range of phosphate mining-related surface disturbance features (approximately 80) were reduced to 13 types or features used in this study—adit and pit, backfilled mine pit, facilities, mine pit, ore stockpile, railroad, road, sediment catchment, tailings or tailings pond, topsoil stockpile, water reservoir, and disturbed land (undifferentiated). In summary, the spatial coverage includes polygons totaling 1,114 hc (2,753 ac) of mine pits, 272 hc (671 ac) of backfilled mine pits, 1,570 hc (3,880 ac) of waste dumps, 26 hc (64 ac) of ore stockpiles, and 44 hc (110 ac) of tailings or tailings ponds.

Salinity remained polyhaline to\r\neuhaline throughout the time of deposition (1800-1997), with alternating periods of\r\nstability and increased fluctuations. Since 1800, a Brachidontes assemblage has\r\ncharacterized Whipray Basin and the dominant faunal components have remained the\r\nsame in terms of presence and absence of species. However, patterns of dominance and\r\ndiversity within the Brachidontes assemblage have changed and these changes indicate\r\nfluctuations in the environment.\r\nThe period from 1815 to 1857 was distinguished by an abundance of molluscs\r\ndwelling on seagrass and sub-aquatic vegetation. Faunal richness and abundance were\r\nhigh and stable, and epiphytic molluscs flourished. Polyhaline conditions existed,\r\nalthough periods of slightly lower salinities occurred. The period from 1862 to 1894\r\nappears unstable based on fluctuations in molluscan faunal richness, abundance, and\r\ndominant species. The epiphytic molluscs experienced significant shifts (? >30%)\r\nassociated with changes in sub-aquatic vegetation. The changes in epiphytic molluscs\r\nfrom 1871 to 1913 may be indicative of a seagrass die-off. The period from 1899 to 1950\r\nwas the most stable section of the core in terms of changes in the molluscan fauna.\r\nFaunal richness and abundance reached highs of 31 groups and 726 individuals per\r\nsample during this period and epiphytic molluscs were prevalent. Beginning in 1955,\r\nfaunal groups experienced high amplitude fluctuations in abundance; this pattern\r\ncontinued through the second half of the 20th century. Fluctuating salinity, changes in\r\nvegetation, and reduced water quality (low O2, increased nutrients and/or reduced clarity)\r\noxygen supply) have characterized the past 50 years. These changes preceded a seagrass\r\ndie-off in 1987-88 and may be related to the causes of the die-off. Whether the cause of\r\nthe changes seen in Whipray Basin is natural or a combination of natural and\r\nanthropogenic factors, the amount of change in the molluscan fauna in the last 50 years\r\nclearly exceeds the preceding 150 years.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr01143","usgsCitation":"Trappe, C.A., and Brewster-Wingard, G.L., 2001, Molluscan fauna from core 25B, Whipray Basin, central Florida Bay, Everglades National Park: U.S. Geological Survey Open-File Report 2001-143, 20 p., https://doi.org/10.3133/ofr01143.","productDescription":"20 p.","costCenters":[{"id":27821,"text":"Caribbean-Florida Water Science Center","active":true,"usgs":true}],"links":[{"id":160388,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":390984,"rank":3,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/of01-143/of01-143.pdf","text":"Report","size":"328 KB","linkFileType":{"id":1,"text":"pdf"},"description":"OFR 2001-143"}],"country":"United States","state":"Florida","otherGeospatial":"Everglades National Park","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -81.9580078125,\n              25.025884063244828\n            ],\n            [\n              -80.013427734375,\n              25.025884063244828\n            ],\n            [\n              -80.013427734375,\n              26.912273826625587\n            ],\n            [\n              -81.9580078125,\n              26.912273826625587\n            ],\n            [\n              -81.9580078125,\n              25.025884063244828\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","contact":"<p><a href=\"https://www.usgs.gov/centers/car-fl-water\" data-mce-href=\"https://www.usgs.gov/centers/car-fl-water\">Caribbean-Florida Water Science Center</a><br>U.S. Geological Survey<br>3321 College Avenue<br>Davie, FL 33314</p><p><a href=\"../contact\" data-mce-href=\"../contact\">Contact Pubs Warehouse</a></p>","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b04e4b07f02db6992ae","contributors":{"authors":[{"text":"Trappe, Carleigh A.","contributorId":37782,"corporation":false,"usgs":true,"family":"Trappe","given":"Carleigh","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":205554,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Brewster-Wingard, G.

We\r\ncollected samples also from Hogum Creek, a tributary to the Blackfoot, from Copper\r\nCreek, a tributary to the Landers Fork, and from ground water seeps contributing to the\r\nflow along the Landers Fork. To better define the physical dynamics of the hydrologic\r\nsystem and to determine geochemical loads, we measured streamflow at all the sites where\r\nwe took samples for water quality analysis. The Upper Blackfoot River, which drains\r\nhistoric mines ca. 20 Km upstream of the study area, had higher trace metal concentrations\r\nthan did the Landers Fork, which drains the pristine Scapegoat Wilderness area. In both\r\nrivers, many of the major elements were inversely related to streamflow, and at some sites,\r\nseveral show a hysteresis effect in which the concentrations were lower on the rising limb\r\nof the hydrograph than on the falling limb. However, many of the trace elements followed\r\nfar more irregular trends, especially in the Blackfoot River. Elements such as As, Cu, Fe,\r\nMn, S, and Zn exhibited complex and variable temporal patterns, which included almost no\r\nresponse to streamflow differences, increased concentrations following a summer storm\r\nand at the start of snowmelt in the spring, and/or increased concentrations throughout the\r\ncourse of spring runoff.

This district is one of many located on or near the Melones fault zone, a major regional suture in the Sierra Nevada foothills. The districts along the Melones fault comprise the Mother Lode gold belt (Clark, 1970).\n\nThe Harvard pit is the largest of several open pits mined at the Jamestown site by Sonora Mining Corporation between 1986 and 1994 (Fig. 2; Algood, 1990). It is at the site of an historical mine named the Harvard that produced about 100,000 troy ounces of gold, mainly between 1906 and 1916 (Julihn and Horton, 1940).\n\nSonora Mining mined and processed about 17,000,000 short tons of ore, with an overall stripping ratio of about 4.5:1, yielding about 660,000 troy ounces of gold (Nelson and Leicht, 1994). Most of this material came from the Harvard pit, which attained dimensions of about 2700 ft (830 m) in length, 1500 ft (460 m) in width, and 600 ft (185 m) in depth. The bottom of the pit is at an elevation of 870 ft (265 m). Since mining operations ceased in mid-1994, the open pit has been filling with water. As of November, 2000, lake level had reached an elevation of about 1170 ft (357 m).\n\nWater quality monitoring data gathered after mine closure showed rising levels of arsenic, sulfate, and other components in the lake, with particularly notable increases accompanying a period of rapid filling in 1995 (County of Tuolumne, 1998). The largest potential source for arsenic in the vicinity of the Harvard pit is arsenian pyrite, the most abundant sulfide mineral related to gold mineralization. A previous study of weathering of arsenian pyrite in similarly mineralized rocks at the Clio mine, in the nearby Jacksonville mining district, showed that arsenic released by weathering of arsenian pyrite is effectively attenuated by adsorption on goethite or coprecipitation with jarosite, depending upon the buffering capacity of the pyrite-bearing rock (Savage and others, 2000). Although jarosite would be expected to dissolve in water having the composition of the developing pit lake, iron oxyhydroxide species (ferrihydrite and goethite) would be stable, and strong partitioning of arsenic onto suspended particles or bottom sediments containing these iron phases would be expected. Arsenic release to the lake would not be expected until stratification develops, producing a reducing, non-circulating hypolimnion in which the iron phases would be destroyed by dissolution.\n\nThe fact that arsenic concentrations increased rapidly before the pit lake was deep enough to stratify shows that arsenic may not be attenuated in the ways that the earlier Clio mine area study indicated, and suggested that our understanding of release and transport of arsenic in this environment is incomplete. Therefore, in 1997 we decided to study the chemical evolution of the Harvard pit lake as part of a project on environmental impacts of gold mining in the Sierra Nevada, and in early 1998 we developed a cooperative study with several of the investigators in the Stanford University Department of Geological and Environmental Sciences who had done the Clio study. The U.S. Geological Survey portion of the project has been funded by the Mineral Resources Program.\n\nIt is anticipated that a better understanding of the release and transport of arsenic into the Harvard pit lake and its accumulation there will contribute to more accurate predictions of arsenic release from weathering of sulfide-bearing rocks exposed by mining or other activities or events, and to better forecasts of pit lake evolution in this and similar environments, leading to more effective monitoring and mitigation strategies.\n\nAn accurate predictive model is needed for the Harvard pit lake to forecast trends in metal concentrations, particularly arsenic, and also concentrations of major cations and anions. As the lake approaches pre-mining groundwater levels the lake water could move down the hydrologic gradient to the southeast into domestic wells, and could also affect the surface water of Woods Creek (see Figures 1-3).\n\nThis report presents data for water samples collected from March, 1998 through September, 1999. Selected preliminary data for the pit lake for the 1998 calendar year have been reported (Savage and others, 2000).","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr0174","usgsCitation":"Ashley, R.P., and Savage, K.S., 2001, Analytical data for waters of the Harvard Open Pit, Jamestown Mine, Tuolumne County, California, March 1998-September 1999: U.S. Geological Survey Open-File Report 2001-74, Report: ii, 13 p.; 3 Tables; Data Table, https://doi.org/10.3133/ofr0174.","productDescription":"Report: ii, 13 p.; 3 Tables; Data Table","numberOfPages":"15","temporalStart":"1998-03-01","temporalEnd":"1999-09-30","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":160560,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr0174.jpg"},{"id":282004,"rank":6,"type":{"id":27,"text":"Table"},"url":"https://pubs.usgs.gov/of/2001/0074/tables2-4.xls","text":"Tables 2-4 Excel format","linkFileType":{"id":3,"text":"xlsx"}},{"id":2803,"rank":8,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/0074/","linkFileType":{"id":5,"text":"html"}},{"id":282003,"rank":5,"type":{"id":27,"text":"Table"},"url":"https://pubs.usgs.gov/of/2001/0074/pdf/table4.pdf","text":"Table 4","linkFileType":{"id":1,"text":"pdf"}},{"id":282002,"rank":4,"type":{"id":27,"text":"Table"},"url":"https://pubs.usgs.gov/of/2001/0074/pdf/table3.pdf","text":"Table 3","linkFileType":{"id":1,"text":"pdf"}},{"id":282001,"rank":3,"type":{"id":27,"text":"Table"},"url":"https://pubs.usgs.gov/of/2001/0074/pdf/table2.pdf","text":"Table 2","linkFileType":{"id":1,"text":"pdf"}},{"id":282000,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0074/pdf/of01-074.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":407176,"rank":7,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_37339.htm","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"California","county":"Tuolumme County","otherGeospatial":"Jamestown Mine","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -120.453,\n              37.955\n            ],\n            [\n              -120.405,\n              37.955\n            ],\n            [\n              -120.405,\n              37.93\n            ],\n            [\n              -120.453,\n              37.93\n            ],\n            [\n              -120.453,\n              37.955\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4acee4b07f02db67fa7f","contributors":{"authors":[{"text":"Ashley, R.
