DEVELOPING A COMPREHENSIVE WATER LEVEL DATABASE TO ASSESS AQUIFER DEPLETIONS IN THE DENVER BASIN, COLORADO
Water level data were collected from Designated Basin data reports, the States Denver Basin and South Platte Alluvial databases, USGS NAWQA and general databases, Centennial Water and Sanitation District database and data collected in a field program. The current database contains over 57,000 water level measurements from 3,814 wells located though out the Denver Basin in one of the four principle aquifers, Dawson, Denver, Arapahoe and Laramie-Fox Hills and an overlying alluvial aquifer. These data were summarized into a single database. The database was screened to include wells that provide well location, ground surface elevation, and aquifer completion information.
The water level data were used to develop potentiometric surface contour maps for each bedrock aquifer for the years 1968, 1978, 1990 and 2002. In addition, 40 hydrographs were developed for individual wells in the bedrock aquifer that had a period of record of at least 10 years and were distributed throughout the Denver Basin. The data were used to assess the aquifer water level trends, as will be summarized. The data collected in this effort can be used for water supply planning studies at a local and regional level. This data provides scientists, planners and engineers the information they need to assess the water availability in the Denver Basin aquifer system.
