Abstract:

The U.S. Bureau of Reclamation is modifying the 335 ft (102 m) high Casitas Dam in Ventura County, California, to withstand a magnitude 6.9 earthquake. The modification includes strengthening the toe of the structure and constructing an earthen berm that will widen and buttress the embankment dam. The 2,000 ft (610 m) long crest also is being widened.
