Johnson Creek Fire & EMS was called as mutual aid to a house fire on East Lake Street in Lake Mills. A multi-family dwelling, the fire started in one of the second story units. A resident of the apartment was transported to an area hospital. Waterloo, Jefferson and Fort Atkinson (WI) departments were called as well. Because a structure resident required medical attention the state Fire Marshal was called to investigate. (PIO arrived after fire was knocked down...ahem.)
