This is a great letter comment letter written by Dr. Pyke to the State Water Resources Control Board criticizing the recent California Water Action Plan specifically regarding the risk of earthquakes in the Delta and the status of the Delta levee system.
Because of course, there is no big risk of an earthquake taking the levees down and the Delta levees are not all ready to fall down, like Westlands Water District, Metropolitan Water District and others wanting the tunnels would like you to believe.
If you want to have the ammunition to counter people who say the tunnels are needed to protect the exports from earthquakes, i.e., the “earthquake bogey”, hear it from the expert. He even calls out the paragraph in the plan that states the risk as “gobbledegook”. A great read and very informative!
Save the California Delta Alliance (STCDA) 
Its time to create Lake San Pablo in the bay, to solve the water needs of California. Building a dam, generating plant & ship locks would prevent salt water intrusion into the delta.
No sweet water would be wasted and the outflow would remain the same.
Interesting thought – but it wouldn’t help the migrating salmon. The outflow wouldn’t be the same because all would flow to the greedy Corporate farmers and for fracking so would be a big negative for the San Francisco Bay. I think instead increasing outflows and keeping the system more natural is a better way to go.
