Rural Douglas County Groundwater Network

History of water-level data collection in the Denver Basin:

• The first comprehensive  measurements of water levels across the basin were made by the USGS from 1956 to 1963 and published by McConaghy and others (1964).
• A second comprehensive set of water-level data for the bedrock and alluvial aquifers through 1981 was published by Major and others (1983).
• Routine water-level measurements by the USGS continued  through the 1980s, were incorporated into the Robson (1987) groundwater flow model, and are available through the USGS National Water Information System (NWIS) (http://waterdata.usgs.gov/co/nwis/gw).
• The USGS NWIS data  were used for model calibration by recent USGS modeling efforts (Paschke, 2010). A water-level monitoring network of  approximately 278 wells was established in the 1980s by the Colorado Divison of Water Resources, and data from that network are published in annual  data reports.
• A compilation and bibliography of all  available water-level data for bedrock and alluvial aquifers through 2004 was published as part of the South Platte Decision Support System.
