Milwaukee County

head of this navigable portion of the river, a dam has been built by the Milwaukee and Rock River Canal Company, which raises the water twelve feet above [the] high water, and causes a slack water navigation extending two miles farther up the stream. A canal of one mile and a quarter, brings this water into the town on the west side of the river, and creates there a water power which is estimated to be equal to about one hundred runs of mill stones; and the canal has a [size] width and depth sufficient to pass almost the whole body of water in the river. The manufacturies erected on this canal, have the advantage of being located on the immediate bank of the river, and may be approached by the largest steamboats navigating the Great Lakes; thus affording advantages not usually found associated; in the western country.
