• <br />Platoro Reservoir Restoration Project <br />Scope of Work (Valve Replacement) <br />� <br />Platoro Reservoir is on the Conejos River and tributary to the Rio Grande River in south central <br />Colorado. It is an earth filled dam with an embanlanent height of 165 feet and a capacity of 59,570AF. <br />The facility is operated and maintained by the Conejos Water Conservancy District. <br />This project repairs, replaces, and upgrades components of the Platoro Reservoir. Recent efforts funded <br />from other sources include installing a bypass piping system to maintain minimum flows during <br />construction and re-coating of the penstocks. The WSRA grant will replace the two valves and operators <br />on the dam. The project will help keep the Platoro Reservoir facility in working order so that Colorado <br />can continue to meet its obligations under the Rio Grande Compact and provide for flood conh-ol, <br />irrigation, river fishery, endangered species protection, dam safety, and recreation, for the 100,000 acre <br />District service area. 'The project will restore the Reservoir to full operating functionality so it can <br />continue to sustainably meet the agricultural demands of the District and therefore optimize existing and <br />future water supplies. <br />The District anticipates the valve replacement work will be completed in October 2009 or 2010 if CWCB <br />funds are not available in time for a 2009 construction season. Scope of work for this activity involves: <br />1. Removal of the existing operator unit <br />2. Removal of a portion of the floor as designed by the USBR <br />3. Removal of the valve and loading it for salvage <br />4. Preparing existing pipe for new valve <br />5. Installing new valve, actuators, switches and associated components <br />6.
