First major upgrade in Sacramento Weir's 104-year history

The U.S. Army Corps of Engineers is funding expansion of the Sacramento Weir. The approximately $350 million project involves widening the 1,950-foot weir an additional 1,500 feet north. 

The weir's 48 manually-operated gates will remain intact. The expansion is constructing a passive weir to essentially allow excessive floodwaters to flow over the river channels and into the bypasses -- in turn widening the surface area, and meaning the Sacramento Weir will be used less frequently for more severe flood events. 

The Corps, Central Valley Flood Protection Board, California Department of Water Resources and the Sacramento Area Flood Control Agency plan to break ground on the Sacramento Weir expansion project in 2021, and estimate the project to be complete in 2023. 

Section - Current Project Activities


  • Team is currently developing 65%-level design for the Sacramento Weir and Bypass component. Design is expected to be completed in Fall 2020.
  • Construction scheduled to start in Spring 2022.
