Los Angeles county officials celebrated the completion of the $100 Million Big Tujunga Dam seismic retrofit project. Big T was built in the early 1930's for flood protection and water conservation. Following the 1971 Sylmar earthquake, a seismic analysis of the dam resulted in its storage capacity being severely curtailed. Now, with nearly 75,000 Cubic yards of concrete reinforcement, the dam is stronger than ever. Sunland, Ca 7-20-2011. (John McCoy/Staff Photographer)
