>> DWR plans stated "worst case flood", using both spillways, to be 10,000 plus years <<

Here is something of note - From the archives of the DWR Oroville Dam, page 93:

States the maximum probable flood has a probability recurrence in EXCESS of ten thousand years. (where both the Emergency Spillway and the Main Spillway would operate together - from high reservoir inflow).
