Washington Water Power Clark Fork River Noxon Rapids Hydroelectric Development, Slacking Tower, South bank of Clark Fork River at Noxon Rapids, Noxon, Sanders County, MT

Significance: The tower is locally important because of its influence, along with the associated Noxon Rapids Hydroelectric Development, on the local environment, landscape and economy. It was integral to the maintenance of the Noxon Rapids tailrace prior to the installation of the slack line cableway. The tower is also important in the history of the Washington Water Power Company, now Avista Corporation. The slacking tower represents late 1950s state of the art technology, now obsolete and soon to be replaced and upgraded with 1990s technology.
