[32] designed capacity of 1,665 second-feet. The gate structure of the siphon inlet would have three lCK-O" radial gates for water control. The wasteway would consist of a gate structure equipped with two lO'-O" radial gates, an open concrete chute, a stilling basin and a transition section, designed to discharge 1,665 second-feet. The total cost of the structure would be $296,573. Drop. A drop structure at Station 963+43 on the alternate route would consist of a rectangular, open channel of concrete 30 feet wide, 12 feet deep and 277 feet long, which would lower the canal grade 8.49 feet. Its designed capacity would be 1,665 second-feet. The estimated cost would be $48,897. Power Drop. At Station 1714-j-OO the proposed canal would enter an abandoned experimental filter basin constructed by the city of Los Angeles. Here, there would be a drop of 17.33 feet. This site was selected for a potential power drop. For location see general map. A preliminary cost estimate of this structure has been prepared by the Denver office of the Bureau of Reclamation. The features of this proposed power drop would be: Normal head 17.33 feet Hydraulic capacity 1,665 c.f.s. Turbine rating 2,680 H.P. RPM 105.8 Power plant capacity 2,200 kva. The estimated cost for this plant would be $1,196,646.
