Oroville Spillways Phase 2 Update

Image: Oroville Spillways Construction Update – July 25

Crews lay roller-compacted concrete (RCC) on the southern half of the emergency spillway splashpad and workers load explosives into bored holes to blast rock near the emergency spillway concrete weir. Excavators clear the blasted material to allow for the placement of RCC to armor the hillside.

Crews also continue placing leveling concrete on the upper chute of the main spillway and place a wall to prepare for the placement of structural concrete on the middle chute.
