The Eagle Roller Mill and the New Ulm Roller Mill combined to make New Ulm the second largest milling center in Minnesota, trailing only Minneapolis. The mill was closed in 1952, shortly after it was acquired by a Minneapolis competitor. The power plant is the only remaining building from the Eagle mill.
