Oroville Spillway Update September 26, 2017

9/27/2017

Roller-compacted concrete (RCC) is hauled from the on-site RCC batch plant and placed in the Lake Oroville spillway’s middle chute, steel plates are installed at contraction joints, and RCC density testing is conducted to ensure quality. RCC work continues through the night, along with structural concrete work on the upper chute.
