Water & Drought
Repairs continue at Oroville Dam. Anchors are placed, side walls are framed, and the first structural slab erected on the upper spillway. On February 7, 2017, dam operators released a gusher of water down the spillway to reduce water levels at Lake Oroville. The heavy flows coming down the spillway apparently exploited weak points in the concrete, and one section of the concrete chute was lifted up, creating a giant crater underneath. The spillway is now under repair in a race to finish before the next rainy season.
