Historic water level data were obtained from the CWCB Basic Data Report #8. This report <br />consists of 663 alluvial wells measured between 1957 and 1961 in the Cache la Poudre Basin. <br />These data were entered into an Excel spreadsheet from hard-copy format. <br />Another database developed and maintained at Colorado State University (CSU) was obtained. <br />This data set includes 168 wells in the alluvial aquifer of the South Platte Alluvium Region. The <br />CSU data were made available in hard copy format and entered into an Excel spreadsheet by <br />DWR staff. The majority of the water levels in this database were measured through the 1970's. <br />Approximately 120 wells in this network were also measured in the spring of 2003 as part of the <br />SPDSS Task 44 effort to obtain recent water level data in the region. <br />A database was obtained from Metropolitan Wastewater Reclamation District. The <br />Metropolitan Wastewater Reclamation District has 24 alluvial monitoring wells located in pairs <br />along the mainstem of the South Platte from 64th Avenue to County Road 32.5. Data consists of <br />118 quarterly water level measurements from 2003 to 2005. <br />The Morgan County Quality Water District provided water levels from 9 alluvial wells located <br />in Morgan County. Data consists of 353 monthly water level measurements from 2003 and <br />2006. <br />An alluvial water level database was obtained from the Rocky Mountain Arsenal. The data <br />were acquired via a request sent to the Department of the Army for well information and water <br />level data for 11 alluvial wells. These 11 wells provide a spatially distributed sample of their <br />monitoring network in western Adams County. These wells are located in the South Platte <br />Alluvium in western Adams County. The data set contains 746 water level measurements from <br />1983 to 2004. <br />The South Adams County WSD provided a water level database for 20 alluvial wells. Data <br />consists of 708 quarterly water level measurements from 1986 and 2005. <br />Additional water level data were collected from the Task 35 and 39 field studies. The Task 35 <br />and 39 water level data are from 38 alluvial monitoring wells installed during Phases 1 and 2 of <br />the SPDSS. Water level data have been recorded on an hourly interval since November 2003 <br />using pressure transducer and data logging equipment. The locations of the wells, discussion of <br />water level measurement techniques and results, and hydrographs of the water level elevation <br />data are reported in the Phase 3 Task 39 TM. <br />The City of Thornton provided alluvial water level data for wells located in the Cache la Poudre <br />River and its tributaries. Thornton has 46 wells that are measured in the spring. Water level <br />data has been collected from these wells once a year in the spring since 1998 and were also <br />collected in November 2002. In addition to water level data from their current monitoring <br />program, historical water level measurements were obtained from the Thornton Northern <br />Project Groundwater Investigations Report (Rocky Mountain Consultants, 1990). During this <br />study Rocky Mountain Consultants collected over 1,800 water level measurements for 55 wells, <br />primarily located in the alluvial systems of the Cache la Poudre River and its tributaries. Data <br />associated with the Thornton Northern Project was provided by Thornton via a series of Lotus <br />spreadsheets. <br />SPDSS Phase 3 Task 44.3 TM -Final <br />11/29/2006 <br />
