Grandfather Falls is the highest waterfall on the Wisconsin River. The total drop is 89 feet, spread out in a series of cascades over about one mile. The upper third of the falls and most of the flow, except in the spring, is diverted through a canal and a series of penstocks to feed hydroelectric generators. Grandfather Falls dam and power generating facility is owned and operated by Wisconsin Public Service Corporation.
