During 1990 and 1991, a series of research flows were released from Glen Canyon Dam. Data collected at the streamflow-gaging station on the Colorado River above National Canyon near Supai from that period have been compiled and entered into the U.S. Geological Survey database. The data consist of measurements of suspended-sediment concentration and sand sizes in suspension, sand sizes of streambed

North-central and northeast Nevada contains numerous large plutons and smaller stocks but also contains many small, shallowly emplaced intrusive bodies, including dikes, sills, and intrusive lava dome complexes. Decades of geologic investigations in the study area demonstrate that many ore deposits, representing diverse ore deposit types, are spatially, and probably temporally and genetically, ass

The Geologic Map of North America (published February 2005) portrays the grand architecture of the continent as we understood it in the closing years of the 20th century. As the final product of the Geological Society of America's Decade of North American Geology project, it was compiled by John C. Reed, Jr. (USGS), John O. Wheeler (Geological Survey of Canada), and Brian E. Tucholke (Woods Hole O

Landforms in Seattle, Washington, that were created primarily by landsliding were mapped using LIDAR-derived imagery. These landforms include landslides (primarily landslide complexes), headscarps, and denuded slopes. Over 93 percent of about 1,300 reported historical landslides are located within the LIDAR-mapped landform boundaries. The spatial densities of reported historical landslides within

The geologic map covers the southernmost part of Texas (parts of Jim Hogg, Brooks, Starr, Hidalgo, Zapata, Willacy, Kenedy, and Cameron Counties), and parts of Nuevo Leon and Tamaulipas, Mexico. Geologic units become younger from west to east across the map area. The oldest rocks are in the western part of the map area in the states of Nuevo Leon and Tamaulipas, Mexico, and include mostly Cretaceo

Anadromous fish populations historically have found healthy habitat in Jordan Creek, Juneau, Alaska. Concern regarding potential degradation to the habitat by urban development within the Mendenhall Valley led to a cooperative study among the City and Borough of Juneau, Alaska Department of Environmental Conservation, and the U.S. Geological Survey, that assessed current hydrologic, water-quality,

Coal-bed methane exploration and production have begun within the Tongue River watershed in southeastern Montana. The development of coal-bed methane requires production of large volumes of ground water, some of which may be discharged to streams, potentially increasing stream discharge and sediment load. Changes in stream discharge or sediment load may result in changes to channel morphology thro

Lake Mohave is one of several multi-purpose reservoirs that have been constructed on the Colorado River. The lake was formed upon completion of the Davis Dam in 1953. Since then, research on this reservoir has dealt primarily with vegetation surrounding the lake (Tallent-Halsell and Walker, 2002), fish (Bozek and others, 1990), water quality (Paulson and Baker, 1983), and geological hazards to rec

This website contains information on faults and associated folds in the United States that are believed to be sources of M>6 earthquakes during the Quaternary (the past 1,600,000 years). Maps of these geologic structures are linked to detailed descriptions and references. NOTE: This database is the source for faults used in the National Seismic Hazard Maps. These faults were altered and values add

The Bluegill landslide, located in south-central Idaho, is part of a larger landslide complex that forms an area in the Salmon Falls Creek drainage named Sinking Canyon. The landslide is on public property administered by the U.S. Bureau of Land Management (BLM). As part of ongoing efforts to address possible public safety concerns, the BLM requested that the U.S. Geological Survey (USGS) conduct

Lead-rich sediments, containing at least 1000 ppm of lead (Pb), and derived mainly from discarded mill tailings in the Coeur d'Alene mining region, cover about 60 km2 of the 80-km2 floor of the main stem of the Coeur d'Alene River valley, in north Idaho. Although mill tailings have not been discarded directly into tributary streams since 1968, frequent floods continue to re-mobilize sediment from

Cattlemans detention basin, South Lake Tahoe, California is designed to capture and reduce urban runoff and pollutants originating from developed areas before entering Cold Creek, which is tributary to Trout Creek and to Lake Tahoe. The effectiveness of the basin in reducing sediment and nutrient loads currently is being assessed with a five-year study. Hydraulic conductivity of the alluvium near

Precipitation is measured at many sites within CPCRW using TE525 tipping buckets. These sensors are able to detect .254mm of precipitation and record hourly totals of rainfall or throughfall. It should be noted the tipping buckets within forested sites are subject to clogging by forest debris which can result in under reporting of rain events as well as over reporting upon release of the collected
