Northern California May Face Significant Risk From Oroville Dam
This statement was from independent expert(s) selected by the state (CA) at the request of the Federal Energy Regulatory Commission (FERC). Good Grief - who in their right minds would be stuffing clay under the spillway slabs?
The admission of this significant point, by independent experts requested by FERC, is very damaging. The act of "stuffing" implies an intentional act of emplacement. DWR engineers must have been aware of this. My oh my.

"The experts called it "absolutely critical" that the dam's state operators not use the faulty emergency spillway again."

"The state should start work now redesigning a new emergency spillway for the 50-year-old dam, the consultants said."
