Seismic retrofits will strengthen Magalia Dam.
Paradise, California: $37.5 million
Project Description
The Paradise Irrigation District Magalia Dam Seismic Retrofit Project lowers seismic risks to boost resilience. It will retrofit the dam to strengthen it. A large earth-fill buttress will be built on the upstream slope of the dam (main dam and saddle dam). A smaller earth-fill buttress will go up on the downstream slope of the dam. The retrofit will protect critical infrastructure, including the dam's water capacity and structure; the adjacent spillway; the nearby downstream roadway; and the downstream water treatment plant. By reinforcing the dam, the project aims to prevent major seismic damage. This way, the infrastructure will stay safe and function during and after seismic events.
