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...
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...

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...

Demonstration optimization analyses of pumping from selected Arapahoe aquifer municipal wells in the west-central Denver Basin, Colorado, 2010–2109 Demonstration optimization analyses of pumping from selected Arapahoe aquifer municipal wells in the west-central Denver Basin, Colorado, 2010–2109
Declining water levels caused by withdrawals of water from wells in the west-central part of the Denver Basin bedrock-aquifer system have raised concerns with respect to the ability of the aquifer system to sustain production. The Arapahoe aquifer in particular is heavily used in this area. Two optimization analyses were conducted to demonstrate approaches that could be used to evaluate...
