The greatest utilisation of power is found among the three counties of Hamilton, Butler, and Montgomery, and in the middle and northern counties of Miami, Anglaize, and Lucas. At Maumee city, some 8 miles above Toledo, the canal is 63 feet above the level of the Maumee river and Lake Erie, and is connected with the former by locks. From this point for 15½ miles, up to the head of the rapids, where the Maumee is rendered tributary for feeding the levels below, there is no lockage. When the canal was built the question of water-power in connection with it was considered, and in the Sixth Annual Report of the Board of Public Works (1843) it was stated that “the capacity of this canal is such that from the head of the rapids to Manhattan 18,000 cubic feet of water per minute can be passed and used for hydraulic purposes without injury to the navigation. At Maumee city the water can be used over a fall of 63 feet; at the locks above Toledo the water can be used over a fall of 49 feet, and at Manhattan over a fall of 15 feet; between these points the canal is so located that the water can be used from it for hydraulic purposes with great convenience, occupying all the fall between the canal and river.” A large amount of power is now used from this portion of the canal by several paper-mills and large flour mills. From the pool above the rapids the succeeding 26 miles of canal, to Independence, is supplied from the river by means of a dam at that place, 9 feet high. From the long level below Independence, the report already quoted from mentions an opportunity to utilise a fall of 23 feet to the river. The portion of canal now referred to was originally known as the Wabash and Erie, being continuous with the Indiana canal of that name. From its junction with the old Miami Canal in Paulding County, to the outlet at Toledo, on the level of Lake Erie, a distance of 64 miles, there is a total descent of 148 feet, effected through 19 locks. This section of the canal was constructed 60 feet wide at the top water-line, and 6 feet deep. From Paulding County the canal takes a quite direct southerly course, and thence to Dayton, 113 miles below the junction, is utilised at frequent intervals for power by flouring-mills, and occasionally by small woollen factories, saw-mills, and other works.
