In 1986 Max Andrae (now retired president of Wisconsin River Power Company) compiled this report.

At the request of Conrad Amacher, I will attempt to relate the history of the Petenwell and Castle Rock projects. The request that prompted this research, made by Mr. Walter Leverance, Tomahawk, only asked for the history of Castle Rock, but, in essence, these two projects should be considered as one as they were essentially constructed at about the same time, and the two projects historically were always considered to be one coordinated project.
