- Laramie-Fox Hills. <br />The water level maps of the Lower South Platte Region will be prepared for up to three <br />distinct time periods (likely within the 1970's, 1990's and for the current year (2002) <br />conditions for each aquifer, including the location of data used in the contouring. <br />For the Lower South Platte Region the mapped aquifers include the following, as defined <br />in the SPDSS Feasibility Study: <br />- Alluvium of the Lower South Platte and its tributaries. <br />The dates and number of mapped time periods will depend on the spatial and temporal <br />distribution of data. The final time periods and number of periods mapped for each Region <br />will be decided in collaboration with the State after the data have been collected and reviewed. <br />Maps of head differences between aquifers within the Denver Basin Region will be prepared <br />from available data, including that of nest (co-located) wells. <br />Hydrographs of groundwater levels also will be prepared for up to 40 wells in the Denver <br />Basin and for up to 20 wells in the Lower South Platte Regions and will be selected to provide <br />a good spatial distribution across each Region and aquifer, as data allow. <br />The Relational and Spatial System Integration and GIS Consultant will provide base maps in <br />digital format to be used for mapping. These will be in the coordinate system and format <br />consistent with other SPDSS products. <br />• The maps and hydrographs will be evaluated and revised based on the presence of outliers, <br />comparison to existing maps and hydrographs, consultation with SEO and CWCB staff <br />familiar with the data, and professional judgment. <br />Deliverables: <br />Task 44.2 Phase 1 Denver Basin Region Aquifer Water Level Technical Memorandum <br />The Consultant will develop a submittal of approximately 10-15 pages (with additional pages <br />for maps and appendices), consisting of the historic data on aquifer water levels and their <br />analysis, as described in Tasks 38 and 44.1. The Technical Memorandum will include the <br />following: <br />- a discussion of the data sources, analysis methods, and results, <br />- a summary of the HydroBase-compatible database fields, structure and contents, <br />- an electronic HydroBase-compatible version of the aquifer water level database, <br />- aquifer water level maps <br />Six hard copies and one digital copy (in MSWord and Adobe Acrobat PDF format) of a draft <br />Technical Memorandum will be provided to the State.
