(Beaver Dam) The Beaver Dam Police and Fire Commission this week approved updated job descriptions for the vacant positions of deputy chief, captain and lieutenant. Fire Chief Michael Wesle recommended only one change: an increase in the number of years of experience for the position of deputy chief. The next chief would need ten years of firefighting experience, instead of five, and now also have three years of experience as a lieutenant. Former Deputy Chief Matt Christian retired in mid-May, six weeks after then-Fire Chief Alan Mannel. Wesle was sworn-in to succeed Mannel last week.
