Depending upon the height and type of embankment used in increasing Lake <br />Meredith storage, the cost per acre-foot of storage ranges between $261 and <br />$1,212, <br /> <br />. Statement of Range Net Evaporation Loss. <br />. The cost range is based on an embankment alignment east of Highway 71. <br /> <br />The Lake Meredith Reservoir enlargement is considered to be a component of CSU' s <br />overall Water Resource Plan, If this plan remains valid based on CSU discussions <br />with the U.S, Bureau of Rec1amation and other water entities/agencies, the following <br />items need to be undertaken to better assess enlargement of Lake Meredith, <br /> <br />1. Updated Survey and Topographic Map <br />2, Expanded Geotechnical Investigation <br />3, Review service outlet and spillway criteria with Colorado State Engineer's <br />Office <br />4, Based on the targeted enlargement alternative, refine the design of the <br />Preferred Embankment Raised Alternatives <br /> <br />URS Greiner <br /> <br />Page 7 <br />
