Mobile siren for Cedar Falls sound test

Seattle City Light staff tested various audible warning sirens near the Cedar Falls Masonry Dam on Wednesday, March 2. Staff picked four test areas and were stationed at nearly 10 sites for sound-level measurements.

The utility will be installing three new warning sirens later this year around the Cedar Falls Powerhouse, Rattlesnake Lake and the Masonry Dam.

The purpose of the siren system is to provide an emergency warning in the event of a dam failure. To learn more about the project, please visit http://www.seattle.gov/light/cedarfalls/.
