Toll Gate Creek dam and reservoir. The potential Toll <br />Gate Creek dam and reservoir would be designed to store the <br />standard project flood and the spillway design flood. In sddi- <br />tion, the reservoir would be designed to contain storage for <br />100 years of sediment runoff. A gated low-level inlet would be <br />provided to regulate reservoir releases. The outlet works <br />would consist of a concrete intake structure with a low-level <br />inlet, a concrete conduit, and a drop structure with a stilling <br />basin at the downstream end of the conduit. The channel between <br />the outlet works and 6th Avenue would be improved to provide <br />capacity for the outlet works releases. Pertinent data for the <br /> <br />56 <br />
