Groundwater Availability Analysis of the Denver Groundwater Basin
The Denver Basin aquifer system is a critical water resource for growing municipal, industrial, and domestic uses along the semiarid Front Range urban corridor of Colorado. The confined bedrock aquifer system is located along the eastern edge of the Rocky Mountain Front Range where the mountains meet the Great Plains physiographic province. Mining, transportation, agricultural, and urban...
Estimation of baseflow characteristics for selected reaches of the South Platte and Cache la Poudre Rivers, northeastern Colorado
Baseflow will be determined for selected reaches in the South Platte River by using a mass-balance approach and possibly by modifying conventional baseflow analysis techniques.
Numerical simulation of the cumulative effects of land-use change and aggregate mines on ground-water flow and wetlands along the South Platte River, Brighton to Fort Lupton, Colorado
The South Platte River valley between the City of Brighton in Adams County and the town of Fort Lupton in Weld County, Colorado, contains many wetland areas that provide habitat for wildlife in the Front Range Urban Corridor. The extent of aggregate mining along this reach of the South Platte River valley continues to increase as the demand for aggregate grows in response to urban development. The...
Historical perspective of Statewide streamflows during the 1977 and 2002 droughts in Colorado
Since the late 1800's, Colorado has experienced several periods of drought that have varied from about 2 to 12 years in duration. The Statewide drought from 1999 extended into 2002, a year characterized by lower than normal precipitation, snowpack accumulation, and streamflow. Statewide, mountain snowpack was about 53 percent of normal on April 1, 2002, the lowest since 1977 Accumulated...
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 up...
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...
Hydrologic assessment of groundwater resources in a foothills watershed in Jefferson County, Colorado
Water quantity, water-quality, and growth issues are of concern to Jefferson County, Colorado, officials who must balance the needs of current (2002) residents and requests for future development with protection and allocation of available water resources. The current status of groundwater resources in the mountainous parts of Jefferson County must be determined as a basis for developing a...
