Newell Creek Dam Inlet/Outlet Replacement Project

Newell Creek Dam Inlet/Outlet Replacement Project

The proposed project would consist of replacement of the existing aging inlet/outlet works in new locations at the Newell Creek Dam and Loch Lomond Reservoir and other associated improvements. Primary components would include a new inlet/outlet structure with three new inlets located within the Reservoir, a new outlet structure and valves at the toe of the dam, a new 10-ft-diameter tunnel containing 48-in and 10-in inlet/outlet pipelines through the right (west) dam abutment and under the dam, a new control house on the dame crest to house controls for the inlets, replacement of an approx 2,000-lf section of Newell Creek Pipeline between the outlet structure and the first isolation valve, improvements along the dam's access roads, and decommission of the existing inlet/outlet works once the replacement system is operational.
