The major demolition of the Oroville Dam spillway is now pretty much completed. Kiewit Corporation is preparing to begin pouring concrete on Thursday. This will be a "leveling" layer, intended to give a proper anchor for the structural concrete to follow.
It has been decided that the more-or-less intact upper 1,000 feet of the main spillway will have to be replaced. It escaped significant damage but all things considered the DWR people want the whole thing redone from the dirt up. Can't say as I blame them.
DWR is still saying that they think-hope that FEMA will pay most of the $275 million bill for the repairs.
The repair project began on May 20 and the first phase must be completed by November 1. The entire project will then move into the second year which will, if all goes well, see the main spillway and the emergency spillway both brought up to the point where a little water won't cause them to have to evacuate 188,000 people again in the near future. Hopefully.
