The boats on this route transported the rich ores from the Sandon area to smelters in Nelson, Trail and in the United States. The establishment of settlements along the northern portion of Kootenay Lake for fruit ranching, mineral extraction and forestry kept this route in operation until the retirement of the Moyie in 1957. The ships also connected the rail line to the north end of Kootenay Lake with the mining developments along the Lardeau River and Trout Lake, as well as isolated settlements with no road access.
The locations of the various landings along the shores of Kootenay Lake and the West Arm are approximations. For some of the landings the only evidence of settlement is the pilings left standing in the water. In other locations all evidence of the landings has been removed and is only visible during low water levels in the spring.
