• Year: 2014
• Document Type - Publications and Reports: Ground Water Levels Report

GROUNDWATER LEVELS IN THE
DENVER BASIN BEDROCK AQUIFERS
2014
This report updates basic data concerning the depth to and elevation of groundwater in the four
main Denver Basin bedrock aquifers collected during the spring of 2014. The report is organized
by aquifer and well location. Well completion information is provided, where available. Wells
that may be completed in more than one aquifer are listed according to the uppermost aquifer.
Approximately 107 water level measurements in this year's report were obtained by Division of
Water Resources (Division) personnel. A total of seven wells have been instrumented with data
loggers to collect daily water -level data. These include the following:
- four wells in the Castle Rock area that monitor all four Denver Basin aquifers;
CO3_LTDW, CO3_TKD, C06_KA and CO3_KLF;
- a well near Bennett, DSSBR01, is completed in the upper Arapahoe; and
- two wells near Golden in the Pleasant View Metropolitan District are completed in the
Arapahoe and Laramie -Fox Hills aquifers.
Water level data from 114 cooperator wells are also included in this report. Personnel from
cooperating water districts and municipalities graciously provided these data upon request. The
Division appreciates the cooperation of the many entities that provide water level information.
Tabular data are presented for each well for the previous ten years. Graphical data show the entire
period of record for each well. Wells lacking measurements in the past 10 years have been
removed from the monitoring program and are no longer included in this publication, although the
data are retained in the Division's HydroBase database.
Analyses of water -levet changes in the aquifers are based on single point comparisons and may be
complicated by unknown pumping schedules or other site-specific hydrologic factors. Table 1
summarizes some of these water level changes for each aquifer.
New to the report this year are color -coded maps showing the change in water levels (by aquifer)
for a one (2013-2014), five (2009-2014) and ten (2004-2014) year period. The changes, both
positive and negative are displayed by color in accordance with the map key.
Included in this report is a summary of the Denver Basin hydrogeology with generalized aquifer
maps and geologic cross-sections.
