The City of Nanaimo will be testing the warning sirens below the Colliery Dams. The low-volume tests will take place between 12:00pm and 5:00pm on Friday, January 3. The sirens will be tested in short bursts. Residents living in the inundation area below the dams are reminded that no action is required because it’s just a test. The sirens are part of the short-term risk mitigation plan approved by the City, while it seeks a long term solution.
