Big Tujunga dam in southern California lost 70 of its storage capac-ity over a four year interval due to heavy sediment loads with the consequence that floodwaves now pass across the spillway only slightly attenuated by the res-ervoir Scott 1973. The dam underwent a seismic retrofit completed in July 2011 which included doubling the thickness of the gravity arch dam. The objective was to moderate the regulation of downstream flood protection and flow releases to sustain habitat.
However in 1976 a State- imposed seismic restriction was placed on the dam that limited the long-term impoundment of water to an elevation of 2213 feet 1484 ac-ft.
