<br />&;~~6r' ~ rior <br /> <br />The project generally involves constructing a new gate structure with a 75% PMP spillway and <br />raising the dam embankment to add additional surcharge storage to the reservoir. The existing gate <br />structure at the southeast outlet of Equalizer Reservoir will be demolished and replaced with a <br />concrete gate/spillway structure. The embankment will be raised I-foot along it's total length of <br />approximately 1000 feet to accommodate surcharge flood storage. The new gate/spillway structure <br />will be constructed approximately 45 feet upstream of the original structure within the natural river <br />channel. The structure will consist of a 26- foot broad crested weir located on the left side of the 28- <br />foot wide gate structure. The five existing gates will be reused to control irrigation releases into the <br />Greeley and Loveland Canal. The structure will be built on a monolithic foundation, which will <br />serve as both an energy dissipating basin for the weir and the floor for the outlet gate structure. A <br />12-foot wide access bridge will be constructed in conjunction with the gate structure. The concrete <br />bridge deck will span the entire structure width of 60 feet. The bridge will be supported at either end <br />by 2-foot thick, 14.7 foot high bridge abutments. The bridge will also be supported mid-span by two <br />2-foot thick, 13.7 foot high retaining walls. The concrete floor slab will sit on the footings of the <br />bridge supports. The upstream and downstream training walls will be I-foot thick and 12.3 feet <br />high, with walls flared at a 550 angle. <br />
