Estimating Evaporative Losses Incurred by Conveyance of City of Albuquerque San Juan-Chama Water: Jemez to Albuquerque

The City of Albuquerque is in the process of implementing the Drinking Water Project, which is part of the Albuquerque Water Resources Management Strategy. As part of this strategy, the City will begin accepting delivery of imported San Juan-Chama water to supplement present municipal water supplies. The City of Albuquerque’s annual allotment of imported San Juan-Chama water is 48,200 acre-...

Comparison of the power consumption coefficient (PCC) method to totalizing flow meter (TFM) for estimating ground-water pumpage in the Arkansas River Valley, Colorado

In the mid-1990s, the Colorado Division of Water Resources (CDWR) adopted rules governing measurement of tributary groundwater pumpage for the Arkansas River Basin. The rules allowed groundwater pumpage to be determined using one of two approaches—power conversion coefficient (PCC) or totalizing flowmeters (TFM). In addition, the rules allowed a PCC to be applied to the electrical power usage...

Hydrogeology and water quality of the shallow unconsolidated-rock aquifers in the Upper Arkansas River Basin from Buena Vista to Salida, Colorado

Population growth near Buena Vista and Salida in Chaffee County has caused concern for the long-term availability and quality of groundwater . Groundwater withdrawals from deep wells that are completed in the basin-fill deposits and designed to supply multiple-dwelling developments could cause drawdowns in water levels of the overlying aquifers. Continued development of groundwater supplies in...

Development of a Plan of Study on the Hydrogeology and Groundwater Resources of the Salt Basin in New Mexico

The New Mexico part of the Salt Basin covers about 2,400 square miles of the south central part of the State. The principal aquifers in the basin are included in the San Andres Limestone, the Yeso Formation and the Abo Formation all of Permian age. Groundwater recharge to the basin is about 35,078 acre-feet per year with about half of the recharge coming from the watershed feeding the...

Stochastic Modeling of Effects that the Sulphur Gulch Reservoir May Have on Colorado River Water Quality near Grand Junction, Colorado

Sulphur Gulch, a new reservoir proposed to be located about 25 miles east of Grand Junction, Colorado, on a tributary to the Colorado River that drains the Sulphur Gulch watershed between De Beque and Cameo, Colorado. The primary use of the Sulphur Gulch Reservoir would be to provide the Colorado River with up to 5,412.5 acre-feet of late-season water in support of the Endangered Fish Recovery...

Sources of Metal Loading to the Lake Fork from Turquoise Lake to the confluence with the Arkansas River

The Lake Fork emerges from the outlet of Turquoise Lake at the Sugarloaf dam and flows approximately 5 miles before joining the upper Arkansas River. The first reach of the Lake Fork downstream from the dam is affected by drainage from abandoned mines in the Sugarloaf mining district. Whereas remediation of some of the mine sites has been initiated, Federal Land holders are interested in...

Arkansas River Water-Quality Data

The Arkansas River Basin drains an area of 24,904 square miles of southeastern Colorado. Like other basins on the Front Range, the Arkansas Basin has experienced growth and is expected to have significant increases in growth in the future. Demands on the limited water resources also will increase as changes in water storage, water releases, and/or transfer of waters within or outside of the...

Water-Quality Assessment of Wolford Mountain Reservoir on Muddy Creek near Kremmling, Colorado

In March 1985 the U.S. Geological Survey (USGS), in cooperation with the Colorado River Water Conservation District (CRWCD), began a monitoring program on Muddy Creek in anticipation of the construction of a water storage project. A site upstream of the proposed reservoir (Muddy Creek above Antelope Creek, 09041090), and a downstream site (Muddy Creek at Kremmling, 09041500) were chosen to...

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...

Distribution of mineral phases in the Eocene Green River Formation, Piceance Basin, Colorado – Implications for the evolution of Lake Uinta

The mineralogy of the Eocene Green River Formation in the Piceance Basin, Colorado, has been the subject of numerous studies since the 1920s. Most previous work has focused on the resource potential of these lacustrine mudrocks, which in addition to substantial oil shale potential (in-place resources of 353 billion barrels of synthetic crude oil...

Rapid station and network quality analysis for temporary deployments

Seismic station data quality is commonly defined by metrics such as data completeness or background seismic noise levels in specific frequency bands. However, for temporary networks such as aftershock deployments or induced seismicity monitoring, the most critical metric is often how well the station performs when recording events of interest. A...
