Document Description
The Bureau of Reclamation proposes to implement the Boca Dam Safety of Dams Modification Project to correct features of Boca Dam to reduce the risk of structural failure during an earthquake event. There is liquefiable alluvium within the dam's foundation, which could cause embankment deformation, cracking, or immediate dam overtopping during a significant earthquake. Boca Dam and Boca Reservoir are located on the Little Truckee River, east of the Town of Truckee and north of I-80 in Nevada County, CA.
