The project will more than double the existing width at the top of the dam and add 80-foot average thickness to the earthen buttress on the downstream side of the existing dam. This will reinforce a section of the dam that has been identified as being susceptible to seismic activity. A significant portion of the project has been completed, which was the construction of new valves and pipeline to be used to control the lake level and allow for fast drainage in the event that water levels need to be adjusted in the event of an emergency.
