<br />constant-speed type, electric motor; a complete machine shop; and <br />a control room from which diversions through the Alva B. Adams <br />Tunnel and releases from Shadow Mountain Lake can be remotely <br />controlled. The pumps have a rated capacity of nearly one-half <br />million gallons per minute for a mroc:imum pumping lift of 186 feet. <br />The pump intakes consist of three reinforced-concr~te conduits, <br />7.25 feet in diBlIl6ter and. 526 feet in length, leading from an in- <br />let trashrack structure in the reservoir. <br /> <br />The pumps discharge into three 87-inch concrete-encased <br />steel pipes that converge into a covered concrete conduit, 11 <br />feet in diameter and. 3,220 feet in length, which discharges into <br />the pump canal. Three 12 to 50-ton traveling cranes, located 'at <br />different levels in the pumping plant, provide for the installa- <br />tion and maintenance of plant equipment through grill-covered <br />openings in intermediate floor levels. An elevator provides <br />access to the seven different floor levels in the plant. <br /> <br />~, <br /> <br /> <br />Granby l'Um:i> Canal.' , <br /> <br />Granby Pump Canal starts at the pumping plant discharge <br />conduit and extends 2.2 miles north to Shooow Mountain Lake. The <br />canal has a 20-foot base width, 2:1 side-slopes, a gradient of <br />0.75 feet per mile" and a capacity of 1,100 cfs for a water depth <br />of 10.5 feet. Construction of the canal required approximately <br />836,000 cubic yards of excavation. At the canal outlet, a gate <br />structure with two 12-foot by 12-foot radial gates controls the <br /> <br />13 <br />
