Consumers Energy announced the emergency public warning siren systems near its Rogers, Hardy and Croton hydroelectric generating plants on the Muskegon River will be tested on Wednesday, December 14, at about 9 a.m.

• The test will include a voice message, a 30-second siren and a second voice message. The public does not need to take any action during the test. The siren systems are tested each August and December.
• The Federal Energy Regulatory Commission requires hydroelectric facilities to be able to quickly notify residents and visitors of any developing emergency at the plants.
• In an emergency, the sirens would be used only if the threat of a dam failure is imminent at one of the facilities. At that time, anyone on or near the river should evacuate at once to high ground. Additional information would be provided on local radio and television stations.

Consumers Energy reminds those who visit dams in the winter that ice on a reservoir near a hydroelectric facility is not reliable and should be avoided by snowmobilers, anglers and others. Also, ice-covered water down river from a hydroelectric facility should never be considered a safe place to walk.
