Tacoma Power to conduct annual siren test at the Cushman Hydro Project on April 7

Tacoma Power will conduct its annual emergency siren test on Wednesday, April 7. The siren at the Cushman No. 2 Dam will sound at 1 p.m. and include an announcement of the test. The test will last about 90 seconds.

The test takes place on the first Wednesday of April every year; it is a requirement of the utility’s federal license to operate its dams.

The test sequence will be:

  • Recorded voice: “Attention – this is a test of the Cushman emergency warning system. This is only a test.”
  • Fluctuating wail for 30 seconds.
  • Recorded voice: “This completes the test of the Cushman emergency warning system. This was only a test.”

Mason County Emergency Management will send three messages about the test via the Mason County AlertSense System (the night before, shortly before the test, and then after the test).
