<br />Executive Summary <br /> <br />The highest scoring subregions in each the alluvial aquifer regions and for the <br />combined bedrock aquifer regions are listed below. <br /> <br />South Platte River Basin Alluvial Aquifer Subregions <br />Lower Lost Creek <br />Upper Lost Creek <br />Lower Kiowa Creek <br />South Platte River - Fort Morgan Area <br />Lower Beebe Draw jBox Elder Creek <br /> <br />Arkansas River Basin Alluvial Aquifer Subregions <br />Upper Black Squirrel Creek <br />Arkansas River - Crowley Area <br />Arkansas River - Lamar to State Line <br />Arkansas River - Buena Vista to Salida <br />Fountain Creek <br /> <br />Bedrock Aquifer Subregions <br />Dawson Unconfined West <br />Arapahoe Confined Northwest <br />Ogallala - North <br />Arapahoe Confined Southwest <br />Arapahoe Unconfined West <br />Ogallala - South <br /> <br />The locations of these areas are shown on Figure ES-1. Specific locations are shown for <br />all subregions except for the Denver Basin. Because of the layered nature of the <br />Denver Basin aquifers, the specific locations of the higher-scoring subregions in the <br />Denver Basin region could not be shown on this figure. Figure 24 in the main report <br />shows the locations of the Denver Basin subregions in more detail. <br /> <br />The scoring results show that for the alluvial aquifers there are high-scoring areas that <br />exist both away from and along the mainstems of the South Platte and Arkansas <br />Rivers. Among the bedrock aquifers, there are high-scoring areas within both <br />unconfined and confined portions of the Denver Basin, as well as the Ogallala. <br />However, there was not much spread in the scores for many of the subregions. <br />Consequently, most of the areas evaluated in this study, regardless of their ranking, <br />could contain feasible underground storage sites worthy of more detailed <br />investigation. The findings in this report, along with site-specific factors outside the <br />scope of this study such as available water supply and local stakeholder interest, <br />should be considered in the selection of areas for further investigation. <br /> <br />The CWCB is a potential source of funding for underground storage projects through <br />means such as the Water Supply Reserve Account created by Senate Bill 06-179 and <br />non-reimbursable grants from the CWCB's Severance Tax Trust Fund Operational <br />Account and Construction Fund.
