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
• Foundation clean-up and placement of dental and leveling concrete continues on the
uppermost 730 feet of the spillway chute. Later this year, crews will place structural
concrete walls and slabs.
• Crews are currently placing structural concrete slabs and walls on the middle chute.
Earlier this year, construction crews removed the temporary roller-compacted concrete
walls on the middle chute. Placement of structural concrete slabs and walls this year
will bring the middle chute to final design.
• Crews have,placed 37 of 378 structural concrete slabs. Crews will install 126 wall
placements as well, for a total of 504 concrete placements this year on the upper and
middle chutes.
• Mechanical demolition of the energy dissipaters, or dentates, at the bottom of the main
spillway continues as crews prepare for a new layer of structural concrete anchored
with epoxy-coated steel dowels.
• November 1, 2018 is the public safety construction milestone to complete placement of
all structural concrete on the main spillway. Dry finishing, concrete curing, joint sealing,
1
completing sidewall backfill and site cleanup will continue on the main spillway after
November 1.
Construction on the Emergency Spillway
• Construction of the southern half of the roller-compacted concrete splashpad is
anticipated to begin July 16. The RCC buttress at the base of the emergency spillway
will be built later this year.
• Work at the emergency spillway site is not dependent on the public safety construction
milestone and will continue past November 1, 2018.
