towpath, began at Middletown between Miami and Erie Lock 31 (Dine's) and 32 (Middletown) at Mile 208. (Mile 0 was on Lake Erie at Toledo, Mile 250 was on the Ohio River at Cincinnati.) This site is about south of the present Central Avenue; Verity Parkway follows the old path of the Miami and Erie (). The canal was supplied by a feeder off the Miami and Erie Canal north at Mile 205 between Lock 29 (Upper Greenland) and Lock 30 (Lower Greenland), south of the Miami Dam. The canal there consumed water at the rate of 1800 cubic feet per minute (850 L/s) (per Morrow's History) or 2000 cubic feet per minute (940 L/s) (per the Historical and Biographical Cyclopaedia). From Middletown, the canal went southeast, through the gentle country the Middletown and Cincinnati Railroad would follow decades later, land filled with sand and gravel deposited by the Wisconsinan Glaciation 14,000 to 24,000 years ago. This geology meant the canal leaked considerably. It proceeded through Lemon Township north of the place later called Oakland. Two aqueducts carried the canal over Dick's Creek, near the intersection of Cincinnati-Dayton Road (the Dixie Highway) and Greentree Road, the state road to the College Township (the aqueducts proved too shallow for use by heavily laden canal boats). It crossed from Butler County into Warren County just north of the northern boundary of the Symmes Purchase, a point today in the city limits of Monroe, near Shaker Run. The canal continued its path southeast into Turtlecreek and Union townships, along the path of Muddy Creek to about where Hagemans Crossing later was on the Cincinnati and Lebanon Pike (U.S. Route 42). There it turned northeast, paralleling Turtle Creek) and crossing it on an aqueduct, approximately the route later taken by the Cincinnati, Lebanon and Northern Railway between Mason and Lebanon. At Lebanon, there was a turning basin in the space bounded by Sycamore Street, South Street, Turtle Creek and Cincinnati Avenue (U.S. Route 42) (approximately ). The canal was fed from water from the North and East Forks of Turtle Creek at Lebanon. The North Fork was dammed by a earth dam to create a (per Morrow's History) to reservoir (per Bogen's "Warren County Canal"). Lebanon was above the elevation of the Miami and Erie Canal at Middletown. Six locks, each long and wide, were necessary to overcome this. Lock 1 was at the
