Personal accounts:
(in a description of Otsego) …”This town is situated on the rapids of the Kalamazoo River, immediately below its junction with the Gun River, and at the head of steamboat navigation. The water power at Otsego is not surpassed by any in Michigan, having a fall of fifteen feet…the concentration of roads leading to it, in connection with its immense water power, render it one of the most desirable points in Michigan….” (From “A twentieth century history of Allegan County” by Henry F. Thomas)
