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
• Crews are continuing foundation cleaning and placing dental and leveling concrete to
prepare for placement of structural concrete walls and slabs on the 730 feet of the
upper chute.
• Slab anchor drilling is complete on the middle chute and crews began placement of
structural concrete slabs on June 26.
• Hydro-blasting of the energy dissipaters, or dentates, at the bottom of the main spillway
is complete. Mechanical demolition will continue to prepare for a new layer of structural
concrete anchored with epoxy-coated steel dowels.
• Removal and replacement is complete of the top layer of a structural concrete slab
placed on the main spillway last year that did not meet DWR's quality control standards
due to a poor surface finish.
• November 1, 2018 is a public safety construction milestone to complete major work
and placement of all concrete on the main spillway. Additional work, including dry
1
finishing and curing of concrete, joint sealing, connecting drainage systems, backfilling
side walls, and site clean-up on the main spillway will continue after November 1.
Construction on the Emergency Spillway
• Construction of the northern half of the roller-compacted concrete splashpad is
complete.
• Foundation preparation in advance of RCC placement at the southern half of the
splashpad site continues.
• Work at the emergency spillway site is not dependent on the November 1 public safety
construction milestone and will continue past November 1, 2018.
Recreation and Other Updates
• The free access program for day use and boat launching at the Lake Oroville State
Recreation Area continues next week on July 5 and 6. The remaining free access days
are August 2-3 and September 6-7.
41 The Thermalito Diversion Pool, and Burma Road and Brad Freeman Trail on the
northern shore of the diversion pool, will re-open to the public from Friday, June 29
through Wednesday, July 4 for hiking, biking, fishing, kayaking and more. Visitors can
access the area off Thompson Flat Cemetery Road.
• DWR and State Parks will re-open a portion of the Dan Beebe Trail between Glen
Pond and Canyon Drive on Friday, June 29. Visitors will have access to over three
miles of trails, which run along the southern shore of the Diversion Pool.
• DWR is investing more than $30 million to build new boat ramp lanes, extend existing
lanes for low-level water access, and add additional parking and new site amenities at
recreation sites across the lake.
• For more information on these recreation improvement projects, visit DWR's Lake
Oroville recreation improvements page.
• The independent Board of Consultants will meet with DWR for the 19th time on July 16
