SEATTLE’S TOLT DAM EARLY WARNING SYSTEM

The City of Seattle owns and operates a dam on the Tolt River. At the request of the City of Carnation, Seattle Public Utilities (SPU) has reconnected the Tolt Dam Early Warning (siren) System. SPU will run a full audible test of the system on November 1, 2025 at noon. Expect to hear loud siren sounds and spoken messages from the speakers.

ANNUAL SIREN TEST AND COMMUNITY DRILL IN CARNATION

10:00 AM: Informational session at Tolt Middle School (3740 Tolt Ave, Carnation, WA 98014). Enjoy coffee and donuts with neighbors while hearing about dam safety!

12:00 PM: Alarm sounds and evacuation drill begins. Walk up the hill from the event, your home, or work. For Evacuation Maps, visit carnationwa.gov/drill

Audible testing of the sirens will occur once a year and be coordinated with the City of Carnation’s annual emergency preparedness drills. The weekly Wednesday noon tests that used to occur will no longer take place.
