Watertown Fire Rescue responded to a report of smoke coming out from the attic at 901 4th Ave NW. Upon arrival crews found smoke coming from the attic space and no visible fire was seen. Firefighters made entry into the upstairs and began fighting the fire in the attic. Due the age of the home and modifications multiple voids were in the attic, this made it difficult to attack the fire. Firefighters battled extreme cold which made fire scene conditions difficult. The house is considered at total loss. Watertown Fire was assisted by Watertown Police and Codington County Search and Rescue.
