OROVILLE UPDATE: Final 2017 Construction Plans for Lake Oroville Spillways Project Approved (with video).
Today, the Department of Water Resources (DWR) provided an update on construction work on the Lake Oroville Spillways Emergency Recovery Project.
DWR received authorization to proceed with its final 2017 construction plan from the California Division of Safety of Dams (DSOD) and the Federal Energy Regulatory Commission (FERC) on July 13 and 15 respectively.
The independent Board of Consultants (BOC) also approved DWR’s construction plans last month pending final approval from FERC.
The first phase of construction includes: Removal and reconstruction of 2,270 feet of the main spillway.
The remaining construction will be completed in 2018, which will also need federal and state approval, includes: Addition of structural concrete to the entire main spillway.
Construction of a roller-compacted concrete buttress (sloped wall) and splashpad on the emergency spillway to dissipate the energy of any waterflows.
The current lake level at Lake Oroville is 800 feet, and reservoir releases into the Feather River are now at 6,500 cfs.
DWR this week finished hosting its second round of community meetings to update residents about the Lake Oroville Spillways project.
