A Race to the Finish on Oroville Dam Spillway Fix

Motion blurred of race track

The scale of the task is immense. Once the spillways are complete, crews will have moved over 1 million cu yd of earth, cleaned 239,000 sq yd of foundation bedrock and crushed 2.3 million tons of aggregate—all in just 18 months.

The Lake Oroville spillway’s 400-acre construction site is an intense flurry of activity. In one corner, an excavator driver uses an old tire as a squeegee to clean away loose rock and prep a foundation. In the steeply sloping spillway chute, a crane operator flies in a rebar cage to workers who tie it into neighboring chute wall segments. Everywhere, dump trucks buzz around the circuitous roadways while rock crushers and batch plants keep pace with dozens of dozers and excavators. Drones hover in the sky photographing and surveying the site, while inspectors pour over every detail of the finished assets.
