Oroville Spillways Construction Update
The Department of Water Resources (DWR) today provided an update on construction
activities for the Oroville Spillways Emergency Recovery Project.
Main Spillway
• November 1, 2018 is a public fety construction milestone to complete placement of
all concrete on the main spillwaysa. Dry finishing, concrete curing, joint sealing,
completing sidewall backfill and site clean-up on the main spillway will continue after
Nov. 1.
• The upper chute is 76 percent complete. Crews have placed 108 of 150 erosion-
resistant concrete (ERC) structural slabs and 14 of 50 ERC structural walls on the
uppermost 730 feet of upper chute.
• The middle chute is 95 percent complete. Crews continue to place ERC structural
slabs and walls on the middle chute. To date, crews have placed 221 of 228 slabs and
76 of 76 walls.
• Hot and high winds affected the surface of a slab during its placement on the middle
chute earlier this month. DWR determined the slab surface did not meet specifications
and plans to remove and replace it. This will not impact the schedule.

• Repair work on the energy dissipaters, or dentates, at the base of the main spillway is
65 percent complete.
Emergency Spillway
• Placement of roller-compacted concrete (RCC) on the southern half of the emergency
spillway splashpad is 83 percent complete. RCC placement resumed on Monday, Sept.
10, after completion of scheduled maintenance on the RCC batch plant.
• Construction of the RCC buttress at the base of the emergency spillway will begin in
October.
• Work at the emergency spillway site is not contingent on the public safety construction
milestone and will continue past Nov. 1, 2018.
Other Updates
• Work continues on an underground transmission line project along Oro Dam Blvd. East
between Glen Drive and Canyon Drive. One-way traffic controls are in place from 6
a.m. to 6 p.m. and will continue until the project is complete in mid-October.
• The speed limit has been reduced to 25 mph on this stretch of Oro Dam Blvd. East and
cars will not be allowed to stop on the road. There are several designated turn outs for
cars to pull over to get a view of the Oroville spillways construction site.
