Updates and Stats on Oroville Spillways Construction
Work continues on the Lake Oroville spillways as crews pour concrete to create the underground cutoff wall downslope of the emergency spillway, assemble electrical towers to reroute power lines away from the spillway, begin installation of the main spillway’s walls, pour and grade structural concrete, and install more stay-forms for drainage.

To repair the spillways, crews are using:
  • 800,000 cubic yards of roller-compacted concrete – enough to fill 245 Olympic-sized swimming pools
  • 146,000 cubic yards of structural concrete – enough to build a 6-foot-wide sidewalk from Sacramento to Los Angeles
  • 55,000 feet of drainage pipe – if stacked on top of each other, the pile would stretch more than 10 miles high
