"The vulnerability downstream has already been identified and it is a ticking time bomb," said Helms. It has enough capacity to hold the entire average annual flow of the Colorado River for two years. Rose said substantial new studies of the dam's stability, flooding in the Kern River canyon and other issues with the dam continue to be worked on. This is difficult to imagine, given its thickness. A large earthquake, for example, could compromise some or all of the structure. Redding would not speculate about what might happen if somehow the dam did breach. Our modeling teams decided to model a counter-factual version of Februarys Oroville Dam breach, in which either (i) the dam continues to disintegrate in a controlled manner or, (ii) in the worst-case scenario, it collapses. The Bureau of Reclamation will have a meeting next month and in October to go over Hungry Horse Dam failure scenarios with local emergency management officials.

FEMA cannot quickly nor easily change the flood maps to incorporate this type of risk explicitly. In preparing for floods, dam operators can lower water levels to allow for 22 billion cubic meters of floodwaters, but this has been devastatingly insufficient in recent years. Those analyses found the dam would remain stable in a major earthquake but prompted EBMUD to raise the embankment, add a modern spillway to supplement its original outlet tunnels and make other improvements. Inspections over the year had been cursory and maintenance ineffective. And then there's the electrical grid. o how is Chabot Dam different from all those bad dams?
