Document Description
The Applicant (Los Angeles County Flood Control District, LACFCD) is proposing to alter the streambed and bank through the removal of approximately 500,000 cubic yards of sediment from the reservoir to minimize impacts to the valves and to ensure The California Department of Water Resources Division of Safety of Dams (DSOD) requirements are met. The Applicant proposes to remove the sediment in the late spring through early winter when inflow in limited. Concurrent with the sediment removal activities, LACFCD also proposes constructing a riser on the dam's lowest outlet gate to allow water above El. 1,230 feet to freely pass through the dam, thus ensuring that DSOD's seismic requirements are met. To make use of the impounded water below El. 1,230 feet, when conditions allow, LACFD will install additional slide gates on the existing risers for the valves.
