Oroville Dam: Damaged main spillway to reopen next week
Oroville Dam’s heavily damaged main spillway is expected to resume releasing water a little more than a week from now as water levels continue to rise in the reservoir.
The state Department of Water Resources announced Wednesday that the battered concrete spillway is likely to begin water releases around March 17. At that point, the water level in Lake Oroville is expected to have risen to 865 feet. That’s well below the point at which water would go over the adjacent emergency spillway, but several feet above the comfort level established by Acting DWR Director Bill Croyle.
The lake was sitting at just below 860 feet Wednesday evening.

I think shot-crete needs about a week to “cure”.
