Document Type: Proceeding Paper

Part of: Waterpower '85


Since initial filling of Canyon Ferry Lake in 1955, wind blown, fine grained material from exposed flats at the upper end of the lake became a problem of increasing concern. Average deposition of dust in the Townsend area, as reported by the Montana Department of Health, amounted to 300 tons per square mile per month, far exceeding the 15 to 20 tons considered as acceptable. This paper describes the problem and discusses the measures taken to solve it.
