Middle Rio Grande Basin Study

The U.S. Geological Survey (USGS) Middle Rio Grande Basin Study was a 6-year effort (1995-2001) by the USGS and other agencies to improve the understanding of the hydrology, geology, and land-surface characteristics of the Middle Rio Grande Basin in order to provide the scientific information needed for water-resources management. The Santa Fe Group aquifer system is the main source of...

Water, Energy, and Biogeochemical Budgets (WEBB): Loch Vale Watershed

Loch Vale is an alpine/subalpine watershed in Rocky Mountain National Park where the U.S. Geological Survey has been conducting research since the 1980s. Our research has focused on the effects of climate change and atmospheric pollutants on water, soil, vegetation, and aquatic life. The alpine/subalpine ecosystem in Loch Vale is sensitive to changes in climate and air pollution. Our long-term...

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...

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...
