<br />.. <br /> <br />.. <br /> <br />. <br /> <br />. <br /> <br />Tasks 38 and 44: Collection, Analysis and Mapping of Water Level Data <br /> <br />Objective: <br /> <br />The objective of these tasks is to (1) compile existing aquifer water level information and create <br />HydroBase-compatible databases with data from the Denver Basin and Lower South Platte <br />Regions, (2) help identifY additional data needs in these Regions, (3) support the design of the <br />groundwater field program described in Task 33, and (4) enhance HydroBase with aquifer water <br />level data collected during the Phase I field activities in Tasks 35 and 36. <br /> <br />Water level data is commonly available as a depth to water rather than an elevation. Therefore <br />ground surface elevation data will be collected and processed as appropriate in order to present <br />water level data as an elevation. <br /> <br />Approach: <br /> <br />Task 38 <br /> <br />Collect Historic Aquifer Water Level and Ground Elevation Data <br /> <br />. Obtain existing electronic databases that are currently maintained by the State and, if <br />available, the USGS and the available paper-copy reports (as identified in Appendix B7 of <br />the SPDSS Feasibility Study) that contain information on ground water levels. <br /> <br />. Obtain digital elevation data from the USGS. Process as appropriate for use in expressing <br />depth to water as an elevation. <br /> <br />Task 44.1 <br /> <br />Analyze and Map Historic Aquifer Water Level Data <br /> <br />. Coordinate with the Relational and Spatial System Integration Consultant to determine the <br />database structure that will be used for entry and/or formatting of these historic data. <br /> <br />. Reformat the existing electronic databases into the appropriate DSS (Hydro Base ) formats <br /> <br />. The Consultant will obtain and review existing available ground water level data for the <br />1950-2000 time period. <br /> <br />. The water level database will include fields for the measurement location, surface <br />elevation, water level and measurement date, accuracy estimate and, where possible, the <br />perforated interval measured and the aquifer being monitored. <br /> <br />. Evaluate whether the non-electronic historic data is suitable for addition to the SPDSS <br />database. These data will be evaluated to determine if it may provide an enhanced <br />understanding of the Denver Basin and Lower South Platte Regions' ground water <br />systems. Data that are necessary for future use to configure, calibrate and use in the <br />groundwater models that are a part of the SPDSS will be converted to an electronic format <br />and added to HydroBase. <br /> <br />. Summarize the database for descriptive purposes, including the database fields, number of <br />entries in each field by aquifer, measurement date, and sources of data. <br /> <br />SPDSS Groundwater SOW, Phase I <br /> <br />Page 16 <br />
