Conclusions <br /> <br />The Continental Dam Rehabilitation Feasibilty Study has been pre- <br /> <br /> <br />pared to provide a detailed evaluation of both the technical aspects <br /> <br /> <br />and financial feasibility of the project. This study has followed the <br /> <br /> <br />guidelines of the Colorado Water Conservation Board for the prepara- <br /> <br /> <br />tion of feasibility reports. Following are the conclusions and recom- <br /> <br /> <br />mendations developed during the course of the study. <br /> <br />1. Seepage Mitigation Plan <br /> <br />The State Engineer's Office has issued a reservoir storage <br />restriction which limits the maximum storage to 15,000 acre-feet for <br />Continental Reservoir, a reduction of more than 7,000 acre-feet from <br />its storage capacity of 22,679 acre-feet at the spillway crest. This <br />restriction was imposed because embankment seepage becomes significant <br />at higher reservoir levels. An investigation into the seepage mecha- <br />nism was conducted and alternative solutions to alleviate these <br />seepage problems were defined. <br /> <br />The conclusion reached was that excavation of a zone of the <br /> <br /> <br />exi sti ng upstream face and then repl acement of that zone wi th an <br /> <br />impervious clay liner would solve the seepage problems.
