OROVILLE, Calif. - The Department of Water Resources (DWR) provided an update on construction-related activities for the Lake Oroville Spillways Emergency Recovery Project. 

Construction is currently being done on the main spillway and the emergency spillway. Road closures have also affected many residents in the area. 

The DWR said that the placement of erosion-resistant concrete slabs began on August 6 on the top 730 feet of the upper chute of the main spillway. 

The placement of the concrete structural walls is expected to come later this month. 

Demolition is finished and by the end of the month crews will begin placing reinforcing steel and concreate framework on the energy dissipaters at the base. 

November 1 is the public safety construction deadline for finishing placement of concrete on the main spillway, but finishing work will continue beyond that. 

See a full list of road closure updates below: 

- Oro Dam Blvd. East was recently reopened to the public. The speed limit has been reduced to 25 mph on the stretch and cars will not be allowed to stop on the road except at designated turn outs where people can get a view of the spillways construction site. 

- An underground transmission project along Oro Dam Blvd. East between Glen Drive and Canyon Drive started on August 8. One-way traffic controls will be in place from 6 a.m. - 6 p.m. as work progresses until it is complte in mid-October.

Light scattered showers are on tap for the start of your Thursday, and I'm tracking heavier rain ahead from Thursday afternoon through mid day Friday. We'll have a lull in our wet pattern late Friday through early Saturday, but even heavier rain and snow will return this weekend and persist into next week. Major travel impacts will be possible across northern California from this wet weather.
