Seismic resilience boost: Priest Rapids Dam undergoes major upgrades

Designed by Stantec, the Priest Rapids Dam received substantial upgrades to improve its seismic resilience. Notably, a new downstream roller-compacted concrete (RCC) dam was built to address liquefaction risks in the existing embankment. The project was designed to withstand an earthquake with a moment magnitude of 7.1, promoting reservoir stability and preventing uncontrolled releases.
