<br />.8. <br /> <br />reservoir is projected to store 5,250 acre-feet. The District's engineer completed a <br />reconnaissance level study on the reservoir. <br /> <br />. <br /> <br />The Districts' engineers ha\'c initiated geotechnical investigations. which are necessary to <br />further refine the construction methods and refinement of preliminary costs associated with <br />the project design. Ln response to questions from the Water Resources Review Committee, <br />staffofthe State Engineer met with representatives of the District at the proposed dam site. <br />The stalTrevicwed the dam site and contributing drainage area. The stafTsubscquently <br />prepared an ahemativc analysis in the determination of the IDF and corresponding reservoir <br />and spillway systems capability to safely route the lDF to prevent overtopping of the dam. <br />The preliminary results indicated a reduction of the IDF of about 13% (44,000 to 38,500 cfs), <br />which results in a potential reduction in spillway size of 20 10 30% contingent on other <br />design features. The results of the alternative study were shared wilh the District's engineers <br />on November 19,2004. The district's engineers are reviewing the alternative study and the <br />stall of the State Engineer is providing assistance as requested. <br /> <br />Jypical Dam <br /> <br /> <br />. <br /> <br />sp-,llW-"i <br /> <br />.. ~~-, <br />*"-. <br /> <br />, <br />_~:.-,-r <br /> <br />- <br /> <br />em'oankTVler1-f dam <br /> <br />The Purpose of the spi1h...ay is to safely conduct the Inilow Design Flood past the dam to prevent <br />overtopping of the dam and subsequent failure and the lose oflife and property damage due to <br />failure of the dam embankment.
