The California Department of Water Resources (DWR) released a video showing before-and-after footage of construction on the Oroville Dam between July 2017 and 2018.

The video offers a fly over of the wreckage, showing the dam’s giant canyons in 2017 juxtaposed with today’s smoothed-over layer of structural concrete. This year, crews are half finished with concrete work on the final two sections of the dam. They have also rebuilt spillway walls and the drainage system, and rebuilt water dissipators at the bottom of the chute.

Erin Mellon, a DWR spokeswoman, told the Mercury News that some work on the main spillway will continue after Nov. 1. This will include concrete curing, joint sealing, filling behind the side walls and clean-up. Work will continue into 2019 to finish an adjacent emergency spillway. The total project cost is at an estimated $870 million.
