SUMMARY <br />W. W. Wheeler and Associates, Inc. and Kumar and Associates, Inc., as requested by the <br />Julesburg Irrigation District, has prepared feasibility level cost estimates for the enlargement <br />of Julesburg Reservoir. The project would include bringing the dam embankments up to <br />current day standards, in -so -far as possible, and would provide for up to 21,900 acre -feet of <br />new reservoir storage. The project would increase the safety of the existing structures, <br />remove restrictions, and provide additional water to assist with the Platte River endangered <br />species issues. <br />Three alternatives for the project were evaluated based on storage levels. These were then <br />subdivided into six options. Wheeler and Kumar developed general facilities layout, feasibility <br />designs, quantity and volume estimates, and prepared feasibility level opinions of probable <br />construction costs for the project alternatives. The work was performed at the feasibility level <br />to characterize the magnitude of the project costs and to make project comparisons between <br />alternatives. <br />Construction costs are generally, commensurate with the magnitude of the construction <br />project, and range from $387,000 for limited improvements to Dam 1 and no storage increase, <br />to $23 million for a complete reconstruction program and maximum storage increase to <br />21,900 acre -feet. Depending on the option selected, the unit price for development of new <br />storage ranges between $2,374 to $1,048 per acre -foot. <br />The project options appear technically feasible. Further studies are needed to fully confirm <br />design assumptions, locate construction materials, establish financial viability, and evaluate <br />potential environmentaLimpacts and permitting issues. <br />2 \reports \97 -1 -500. nk <br />
