Watertown was first settled by Timothy Johnson, who built a cabin on the west side of the Rock River in 1836. The area was settled to utilize the power of the Rock River. The City of Watertown joined the Rock River Stormwater Group in 2020. Watertown sits on the border between Dodge and Jefferson counties, with a population of more than 23,000. The Rock River wraps around the town as it cuts through the downtown area.
