A 10-foot long, 300-foot wide riprap energy dissipating basin would <br />be constructed at the toe of the chute to dissipate the energy. Training walls would be placed along <br />the sides of the chute, as well as along the doWIlStream faces of the entrance slopes to direct the flow <br />into the discharge chute. <br /> <br />The recommended alternative for Hoffinan Reservoir Spillway consists of widening the <br />existing concrete weir structure to 30 feet and removing and replacing the existing bridge as shown <br />in Figure IV-8, The control weir would be a 12-inch wide weir with a crest elevation of 4958'20, <br />The existing span of the bridge abutments and footings would allow the widening of the weir to take <br />place at the existing site. The existing bridge would have to be removed during construction and then <br />replaced on the original abutments. <br /> <br />The recommended alternative for Houts Reservoir involves constructing a 4-foot by 4-foot <br />box culvert with dual2-foot by 4-foot gates upstream, as shown in Figure IV-17, The gates would <br />be used to regulate the flow between the two reservoirs and would be closed during the winter to <br />maintained the water surface in Houts Reservoir while Equalizer Reservoir is drained, <br /> <br />The recommended alternative for Lake Loveland North Outlet involves relocating the <br />structure upstream with a new gate structure, The old structure would be removed and replaced with . <br />a 8-foot by 8-foot box culvert. The relocated structure would consist of a 2-foot thick wall with four <br />48-inch and two 24-inch slide gates mounted on the upstream face of the wall as shown in Figure IV- <br />6. The structure would also have 10-foot wing walls upstream and a 48-inch grated walkway to <br />access the gate hoist structures. The design flow is based on the decreed flow of the Big Barnes <br />Canal, which discharges into Lake Loveland, <br /> <br />The recommended alternative for the Greeley and Loveland Irrigation Canal involves <br />modifYing the canal geometry and replacing the existing concrete liner. In order to pass the decreed <br />flow of 4.46 cfs through the upper Greeley and Loveland Canal system, the cross sections of the canal <br /> <br />E:\G&.LREPOR.
