^ As State resources allow, expand the bedrock water level monitoring network to include <br />locations and aquifers where data gaps exist, including the deeper central portion of <br />each of the aquifers. <br />Additional effort should be considered to obtain historical water level data for the <br />aquifers and time periods where data gaps exist. This might include soliciting more <br />entities for historical data and obtaining static water level information from well <br />permits. <br />HydroBase should include a field in its water level measurement table that indicates if <br />the water level measurement was collected under pumping or non-pumping conditions. <br />For data solicited from outside entities, the State should evaluate the data to determine if <br />the measurements represent pumping or non-pumping conditions. This could be <br />accomplished by analysis of hydrographs from individual wells and by evaluating <br />records eliminated from contouring in this TM. <br />The water level data presented in this TM should be used to develop continuous <br />potentiometric surface maps of each aquifer for use as initial aquifer water levels and in <br />model calibration of a Denver Basin Region bedrock aquifer groundwater model. <br />6.0 References <br />Castle Pines Metropolitan District. 2005.
