<br />necessary to provide capacity for floodflows originating down- <br />stream from the dams. <br /> <br />30 . SELECTED PLAN <br /> <br />a. General. In the Sand Creek basin, the selected plan <br />of improvement consists of the Sand Creek dam and reservoir, the <br />Toll Gate Creek dam and reservoir, and the improvement of the <br />Sand Creek channel between East Colfax Avenue and the South <br />Platte River and the Toll Gate Creek channel between the dam <br />and Sand Creek. <br /> <br />b. Sand Creek dam and reservoir. The potential Sand <br />Creek dam and reservoir would be designed to store the standard <br />project flood. The emergency spillway would be perched 17 feet <br />above the standard project flood pool and would control about 36 <br />percent of the spillway design flood. In addition, the reservoir <br />would be designed to contain storage for 100 years of sediment <br />runoff. A gated-outlet works with a low-level inlet would be <br />provided to regulate reservoir releases. The outlet works <br />would consist of a concrete intake structure, a concrete conduit, <br />and a stilling basin at the downstream end of the conduit. <br />Pertinent data for the potential Sand Creek dam and reservoir <br />are shown in table 10. <br /> <br />55 <br />
