Data Flow Process <br />During this phase, water level data was obtained from HydroBase and newly identified <br />databases were added to a temporary HydroBase-compatible SPDSS database used for this <br />study. This SPDSS database was queried for water level data in selected time periods and <br />analyzed. The data in this TM is presented in several forms to depict spatial and temporal water <br />level tends. This process is very similar to the process that was undertaken in the South Platte <br />Alluvium Region (Task 44.3) Water Level TM. The HydroBase-compatible SPDSS database will <br />be submitted to the DWR at the end of this phase so that all new data can be incorporated into <br />HydroBase by the DWR. <br />1.1 Sources of Data <br />Several sources of water level data were used to compile a water level database for this study. <br />Water level data were gathered from both public and private sources for the Denver Basin <br />Region, water level data collected for the South Platte Alluvium Region is discussed in a <br />separate TM (Task 44.3). Sources of data collected during this study included the Colorado <br />Division of Water Resources (DWR), U.S. Geological Survey (USGS), Castle Pines Metropolitan <br />District, Castle Pines North Metropolitan District, Centennial Water and Sanitation District <br />(WSD), Donala WSD, Thunderbird Water District, and SPDSS field studies, as summarized in <br />Table 1. <br />Table 1: Summary of Water Level Data for the Denver Basin Region <br /> <br /> <br />Source Number of Bedrock <br />Wells with Water <br />Level Data Number of Bedrock <br />Water Level <br />Measurements <br />1.

This water level data has been <br />enhanced with additional data identified during this phase of Task 44. <br />During this phase of the SPDSS, several additional bedrock water level databases were <br />identified and obtained from entities within the Denver Basin Region. Data from these entities <br />were added to data already in HydroBase to be used in this analysis. The following is a brief <br />SPDSS Phase 3 Task 44.2 TM -Final 3 <br />11/28/2006 <br />
