A quarry was opened in a canyon north of town to provide stone for the foundation.

The mill opened on September 5, 1905, and was granted an electric light franchise by the town the day before.

The generating equipment was installed by the Western Electric Company of Omaha, and produced enough surplus power to operate street lights in town.

[2] As of March 2012, Toomey's Mill was torn down and was replaced by a convenience store.
