The Outlet Study <br />concluded that routing the pipe completely around the dam may reduce or eliminate <br />regulatory agency requirements. In order to route the pipe completely around the dam, <br />the pipe would need to be located in Alvarado Rd. Regulation of flow through the by- <br />pass pipe would be with a 42-inch diameter regulating gate valve at the downstream <br />end of the pipe. The valve would be housed in a valve vault and would discharge into a <br />concrete discharge structure on the bank of the creek downstream of the existing <br />spillway. A bulkhead gate at the intake structure would allow drainage of the pipe for <br />inspection. Based on the topography, it appears that the intake structure could be <br />located between the West side of the reservoir and the East side of Alvarado Road and <br />would consist of a trash-rack, the bulkhead gate, and a bubbler system to prevent ice <br />formation at the stem. <br />The Outlet Study goes into further detail with respect to; <br /> Site Information <br /> Existing Features <br /> Alternate Designs <br /> Cost Comparisons <br /> Comprehensive Analysis of Alternatives <br /> Recommendation <br />The reader is referred to the full report Outlet Study for more details. <br />Recommended Alternative : The Outlet Study recommended Alternative #3, a new bypass <br />around the dam, listing several reasons: <br /> Alternative 3 is least likely to be influenced by currently unconfirmed factors. <br /> Alternative 3 uses traditional construction techniques.
