<br />. <br /> <br />1 . <br /> <br />Raise the height of the dam, enhance the spillway, and <br /> <br /> <br />stabilize the dam by placing additional material on the <br /> <br /> <br />downstream face. This alternative would allow full passage <br /> <br /> <br />of the probable maximum flood (PMF). The estimated cost is <br /> <br /> <br />$5.25 million. <br /> <br />2. Raise the height of the dam and place additIonal material on <br /> <br /> <br />the downstream face of the dam. This alternative would <br /> <br /> <br />allow the dam to pass one-half of the probable maximum <br /> <br />flood. It is estimated to cost $1.04 million. <br /> <br />3. Limit the storage capacity of the reservoir to about 35,000 <br /> <br /> <br />acre-feet and provide a flood warning system. This <br /> <br /> <br />alternative would allow the dam to pass one-half of the <br /> <br /> <br />probable maximum flood. Is estimated to cost $360,000. <br /> <br /> <br />Such a limitation on storage would make it impossible to use <br /> <br /> <br />the facility for compact purposes. <br /> <br />Because of the cost of alternative 1, the district's <br />engineer has not recommended it. Rather, he recommends that <br />alternative 2 be selected for construction. Alternative 3 has <br />been rejected because it would limit storage to 35,000 acre-feet, <br />the potential annual loss of 17,000 acre-feet of storage being <br />too costly for the water users to endure over the years. <br /> <br />. <br /> <br />-3- <br />
