Xcel Energy will conduct a semi-annual test of the dam failure warning sirens below Trego Dam on the Namekagon River today, Monday April 6th, at 11:00 am.  The test will last about 90 seconds and involve a series of audible tones and messages. The test is in coordination with Washburn County Emergency Management, the National Park Service, and local townships.  Anyone with questions about this test should contact Xcel Energy’s 24-hour Customer Contact Center at 1-800-895-4999.

George Scott: There are many smaller dams in Wisconsin that have been abandoned or are receiving minimum maintenance. A number of years ago a dam in DD Kennedy park on the Balsam Branch in Polk County partially collapsed causing a 6 foot crest to roll down stream into Lake Wapogasset and the Apple River. A few years before that another dam near Osceola collapsed causing the closing of Wisconsin 35 for about a year.
