Cedar Falls Masonry Dam

PROJECT OVERVIEW

The Cedar Falls Hydro Project is a multi-use facility originally built in the early 1900’s. The primary purpose of the facility is to provide drinking water. The facility also provides hydropower, flood mitigation, local fire system water supply and Habitat Conservation Plan resources.

In 2016, Seattle City Light will be increasing its dam safety measures in the Cedar River Watershed by installing three new warning sirens at the Cedar Falls Powerhouse, Rattlesnake Lake and the Masonry Dam.

The purpose of the system upgrade is to provide an audible warning system for emergency situations. In particular, the system will provide a warning in the event of a dam failure. Due to the unpredictable nature of emergencies, one of the best ways to mitigate safety hazards is to provide warning measures that focus on the safety of City Light staff, customers and the surrounding community.
