A dam site at Salmon Falls was too low in elevation to allow for the ditch to exit the river canyon between Red Bank and Mormon Island. Consequently, the dam site was moved to Rocky Bar which had an elevation of approximately 450 feet. With a small dam across the river, the headwaters for the canal would be elevated to 465 feet. The minimal slope of the ditch line would put the water canal at between 390 to 395 feet of elevation at the saddle.
