description of each of the databases that were obtained during the SPDSS and contain bedrock <br />water level data. <br />Donala WSD provided water level data for 11 bedrock wells that are completed in the Dawson, <br />Denver and Arapahoe Aquifers, most of which were measured monthly during 2003 and 2004. <br />A second database was obtained from Castle Pines Metropolitan District. The Castle Pines <br />database contains 7 bedrock wells that are completed in the Lower Dawson, Denver, and <br />Arapahoe Aquifers. Water levels were collected at various time intervals from 1986 to 2002 <br />depending on when each of the wells had been instrumented with automated water level data <br />loggers. Average daily values of water levels were computed when measurements were <br />recorded more than once a day. <br />A third set of water level data was from Castle Pines North Metropolitan District. Castle Pines <br />North has 11 bedrock wells that are completed in the Lower Dawson, Denver, and Arapahoe <br />Aquifers. Wells in the Castle Pines North Metropolitan District database have been collected <br />since 1985 and more recently instrumented with automated water level data loggers. Average <br />daily values were computed for water levels recorded more than once a day. <br />A fourth set of data was obtained from Centennial WSD. This database includes a tota148 <br />different wells. Of these 48 wells, water level measurement data was provided for only 26 <br />wells. Water levels for the Laramie-Fox Hills Aquifer wells were not included in the data set. <br />Wells in this data set include water level information for the Denver and Arapahoe Aquifers <br />from 1999 to present. <br />A fifth data set was obtained from the Colorado Division of Water Resources. The DWR has <br />been collecting bedrock water level measurements once a year in the spring since 1988. The data <br />set contains water level measurements from 289 wells located in the Denver Basin. This data set <br />continues to be populated with additional water level data collected as part of the DWR's <br />bedrock water level measurement program. <br />A sixth set of data was provided by Thunderbird Water District, a water supplier in Douglas <br />County with a well completed in the Arapahoe Aquifer. Water level data from this well consists <br />of quarterly water level measurements from 2000 to 2005. <br />A seventh data set was obtained from the USGS by the DWR, from a complete download of the <br />USGS general water level database for the entire State of Colorado. The data set contains water <br />level measurements for both alluvial and bedrock aquifers for selected historic time periods that <br />were not obtained during Phase 1. The data located in Water Division 1 was provided by the <br />DWR and was queried for bedrock wells located within the SPDSS study area for the current <br />analysis. <br />An eighth water level data were collected from the SPDSS Task 36.1 and Task 39.1 field <br />investigations. The Task 36.1 water level data, from a bedrock monitoring well installed in the <br />Upper Arapahoe Aquifer during Phase 1 of the SPDSS, were recorded on an hourly interval <br />from May of 2004 to June of 2006, using pressure transducer and data logging equipment. <br />Average daily water level values were computed using the hourly measurements.
