What are the ranges of reservoir sizes that are practical? <br />5, What methods can be used to enlarge Lake Meredith? and <br />6, What are the costs and impacts of the various reservoir sizes? <br /> <br />A. EXISTING DELIVERY SYSTEM EVALUATION AND FINDINGS <br /> <br />On March 24, 1998, URSG and Colorado Canal staff conducted a site visit of the <br />Colorado Canal, Lake Henry, Lake Meredith and Lake Meredith Outlet Canal to <br />review general facility conditions, and possible constraints and opportUnities to <br />enlarging Lake Meredith, The Colorado Canal to the Sugar Flume is rated for <br />750 to 800 cfs, To date, there has been no overall hydraulic review of the canal's <br />capacity and no hydrologic review of drainages that discharge into the Canal. The <br />most recent hydraulic reviews have centered on the Canal's appurtenances and <br />measuring devices, In general, the existing Colorado Canal/Lake Meredith <br />delivery and storage system is in overall good condition based on its current mode <br />of operation and the amounts of annual delivery and releases, The following <br />findings and recommendations should be implemented to identify constraints and <br />opportunities for increased water deliveries and releases, <br /> <br />1. COLORADO CANAL <br /> <br />. A hydrologic and hydraulic review of the entire delivery system should be <br />conducted to better determine operational constraints and opportUnities. <br />. Conduct a feasibility study on installing a sedimentation basin that IS <br />similar to the CF&I facility on the Arkansas River in Florence, Colorado. <br />. Review bank stabilization requirements on several side channel laterals. <br />. Further investigate the Bob Creek Delivery System and the potential for <br />changing the delivery system alignment (i,e, reroute through field drain <br />channels back to Lake Meredith) based on the selected reservoir capacity <br />and corresponding high water level. <br /> <br />URS Greiner <br /> <br />Page 2 <br />
