A coalition of environmental groups has called on California members of Congress to prioritize the San Luis (B.F. Sisk) Dam seismic remediation over federal funding for new California dams. San Luis Dam is in a very seismically active area. Independently reviewed risk assessments for Reclamation have shown that a large earthquake could lead to crest settlement and overtopping of the dam, which would result in large uncontrolled releases and likely dam failure.
