The local grand jury released a report detailing conditions in Ventura County's dams, several of which are in bad shape, at risk of failure from flooding or major earthquake (not that we would ever have one of those in SoCal).
This is relevant because some 90 years ago, the St. Francis dam, located on a tributary of the Santa Clara River, burst, sending a wall of water some 140 feet high to the Pacific Ocean, killing some 450 people in the process...Today that region is even more developed and populated. Work is proceeding on redressing some of the problems, but the work ain't cheap nor easy.
Here is a link to the full report;
