Lake Oroville Spillways Construction Update
Today the Department of Water Resources (DWR) provided an update on construction-related
activities for the Lake Oroville Spillways Emergency Recovery Project.
Construction on the Main Spillway
• Placement of erosion-resistant concrete, or ERC, structural slabs began
Monday, Aug. 6, on the uppermost 730 feet of upper chute. Placement of
ERC structural walls is anticipated to start later this month. This section of
upper chute is 45 percent complete.
• Placement of ERC structural slabs and walls on the middle chute
continues. Crews have placed 109 of 228 slabs and 21 of 76 walls to
date. The middle chute is now 58 percent complete.
• Demolition is complete and crews will begin placing reinforcing steel and
concrete framework on the energy dissipaters, or dentates, at the base of
the main spillway in the coming weeks. Placement of structural concrete
on the dentates is anticipated to begin near the end of August.
• November 1 , 2018 is a public safety construction milestone to complete
placement of all concrete on the main spillway. Dry finishing, concrete
curing, joint sealing, completing sidewall backfill and site clean-up on the
main spillway will continue after November 1 .
Construction on the Emergency Spillway
• Crews continue placement of roller-compacted concrete, or RCC, on the
southern half of the new emergency spillway splashpad, which is 58
percent complete.
• The RCC buttress at the base of the emergency spillway weir will be built
later this year. Drilling of steel dowels into the emergency spillway
monolith structure that will support the buttress is 94 percent complete.
• Work at the emergency spillway site is not dependent on the public safety
construction milestone and will continue past November 1 , 2018.
Other Updates
• Oro Dam Blvd. East was recently reopened to the public. The speed limit
has been reduced to 25 mph on this 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 today, Wednesday, Aug. 8. One-
way traffic controls will be in place from 6 a.m. to 6 p.m. as work
progresses until it is complete in mid-October.
• September 6 and 7 are the next free access dates at the Lake Oroville
State Recreation Area as part of DWR's free access program.
• DWR will meet with the independent Board of Consultants for the 19th time
on September 5 and 6.
