The dam is <br />located on the East Fork Creek, which is tributary to West Beaver Creek. The <br />purpose of this study is to recommend remedial action to be taken to best utilize <br />the 1 imited water available to the City of Victor. Specifically, this involves <br />evaluating alternatives available to the City to restore the Victor No.2 Dam to <br />its historic water storage capacity by providing a stable embankment and adequately <br />sized emergency spillway. <br /> <br />In March 1984, the City of Victor informed the Colorado State Engineer that <br />longitudinal cracking had recently been discovered on the crest of Victor No. 2 <br />Dam. On June 7, 1984, an inspection of the dam was made by the State Engineer's <br />Office. This inspection resulted in a letter from the State Engineer dated June <br />22, 1984, which directed the City to restrict the level of water in the reservoir <br />to an elevation approximately 8-feet below the dam's crest. This was recommended <br />as a safety precaution, since the existing emergency spillway for the dam was <br />determined to be hydrologically inadequate to pass the required design flood. <br />Lowering the dam level required that the existing spillway be excavated down 1.5- <br />feet to maintain 8-feet of freeboard. By lowering the emergency spillway crest, <br />the City lost approximately 23 acre-feet of water storage. <br /> <br />The State Engineer's Office also recommended that the City hire a professional <br />engineer to investigate the cracking problem, evaluate the hydrologic adequacy of <br />the emergency spillway, and to design the appropriate remedial measures necessary <br />to bring the dam and emergency spillway up to present-day design standards. <br /> <br />Flood hydrology for the basin was completed to evaluated three different design <br />storm events. The flood events evaluated include: the Probable Maximum Flood, <br />1/2 of the Probable Maximum Flood, and the IOO-Year Flood Event. A result of the <br />peak discharges and volumes at the Victor No.2 Dam for each event is presented <br />below: <br /> <br />1 <br />
