Using GIS and Multivariate Regressions to Model Salt and Selenium Loads in Regions of the Upper Colorado River Basin

Elevated loads of salt and selenium can impair the quality of water for both anthropogenic and natural uses. Understanding the environmental processes controlling how salt and selenium are introduced to streams is critical to managing and mitigating the effects of elevated loads. Dominant relations between salt and selenium loads and environmental characteristics can be established by using...

Water-Quality Sampling at Five Hydrologic Benchmark Stations in the Western United States

The Hydrologic Benchmark Network (HBN) was established in 1963 to provide  Swiftwater Creek, MT long-term measurements of streamflow and water quality in areas of the United States that are minimally affected by human activities. Historically, the HBN has used a fixed-interval sampling strategy, however other more robust sampling strategies are now available. Trend networks, for example, can...

Water-Quality Monitoring of the Vallecito Reservoir Watershed

The water quality of the Vallecito Reservoir watershed in southwestern Colorado was initially studied by the U.S. Geological Survey (USGS) during July 1996 to July 1997, in cooperation with the Pine River Irrigation District, to assess the suitability of the reservoir as a potential source of drinking water (Ranalli and Evans, 1999). As a result of this study, in December 1997 a group of...

Effects of increasing urbanization on ground- and surface-water resources in the Fraser River watershed

The USGS has assessed the effects of increasing urbanization on ground- and surface-water resources in the Fraser River watershed. The population of Grand County increased 93 percent between the years of 1970 and 1990. The majority of the new development in the watershed will rely on ground water and individual septic disposal systems (ISDS's). This study has assessed the potential effects of...

Effects of Fluvial Tailings Deposits on Receiving Waters in the Upper Arkansas River Basin, Lake County, Colorado

Fluvial tailings deposits stored in the floodplain of the upper Arkansas River represent a potential nonpoint source of contamination to surface and ground waters. The U.S. Geological Survey has been cooperating with the U.S. Environmental Protection Agency to monitor a lowcost, insitu remediation technique for the deposits. Remediation of selected sites occurred in 1998 through 2000 by...

Groundwater-level data for the Albuquerque Basin and Adjacent Areas

The Albuquerque hydrologic basin extends along the Rio Grande from Cochiti in the north to San Acacia in the south. Increases in groundwater pumping to accommodate population growth in the basin resulted in substantial groundwater-level drawdown in some areas.

Groundwater Monitoring in the Espanola Basin Piezometers

In 1996, the U.S. Geological Survey, in cooperation with the City of Santa Fe, and the New Mexico Office of the State Engineer began a drilling program to install specialized monitoring wells in the Espanola basin. The purpose of the program is to monitor hydraulic head at specific depths in the aquifer. Most of these specialized wells, called piezometers, are located in areas between major...

Establishing chronologies for alluvial-fan sequences with analysis of high-resolution topographic data: San Luis Valley, Colorado, USA

On active alluvial fans, debris-flow deposits and frequent avulsions produce a rough topographic surface. As is the case in many initially rough landforms produced by catastrophic processes, the topography of alluvial fans is progressively smoothed, producing textural differences useful in establishing relative age criteria for fans. Here, we...

Methodology for correcting bottomhole temperatures acquired from wireline logging measurements in the onshore U.S. Gulf of Mexico Basin to characterize the thermal regime of total petroleum systems

Characterization of the subsurface thermal regime is critical for understanding many facets of the petroleum system, from thermal maturation of organic-rich source rocks to thermal preservation and non-degradation of hydrocarbon accumulations. On a broad scale, paleo-heatflow has been mapped for the North American continent (Blackwell and Richards...

Fire, vegetation, and Holocene climate in a southeastern Tibetan lake: a multi-biomarker reconstruction from Paru Co

The fire history of the Tibetan Plateau over centennial to millennial timescales is not well known.
