Part of: Waterpower '85


The project includes rehabilitation of a timber crib dam and the first use of a Right Angle Drive turbine in the United States to generate power from the 16 feet of head available at the site. Prior to redevelopment efforts, the Hackett Mills site was an old mill which was destroyed by fire in the early 1970's. The mill had been retired as a production facility and was used as warehouse. Power had not been produced for at least 20 years. The existing facilities consisted of a decaying timber crib dam, two concrete abutment sections in good shape, a canal intake in need of repairs, a 100 foot concrete canal, a small concrete powerhouse and a silted tailrace. This paper discusses institutional considerations, conceptual design, turbine equipment, and the powerhouse.
