A public warning siren and speaker system will be tested Thursday.

Consumers energy will be conducting the emergency warning systems along the Manistee River at the Tippy and Hodenpyl hydroelectric generating plants starting at 9:30am.

The sirens are located near Tippy dam, High Bridge U.S. Forest Service boat launch, Hodenpyl dam, and Red Bridge U.S. Forest Service boat launch.

The tests will include a voice message, a 30-second siren and a second voice message about the test.
