foot of Clay Street in Lebanon. Lock 2 was a short distance downstream, still in Lebanon. Lock 3 was about a mile (2 km) southwest of Lebanon near Glosser Road and Turtle Creek. Lock 4 was about southwest of Lebanon near the confluence of Muddy Creek and Turtle Creek and what was later Hillcrest and Hagemans Crossing. These locks raised and lowered boats a total of . At Lock 3, Joseph Whitehill, later Ohio State Treasurer, operated a grist mill, having purchased water power from the State. Lock 5 was near the intersection of Greentree and Cincinnati-Dayton Roads, where the feeder canal from the Miami and Erie Canal entered. Lock 6 was at Middletown, near where the canal debouched into the Miami and Erie Canal. These two locks raised and lowered boats the remaining , by each lock. Shaker Run wrecks the canal In 1848 the stream Shaker Run forever damaged the canal. Shaker Run, in western Turtlecreek Township, drained the large swamp on the Shaker settlement at Union Village. The stream frequently jumped its banks and flooded the canal, depositing sediment that required constant dredging and repairs. Finally, Shaker Run broke through the canal's embankment. In 1852, John W. Erwin, the resident engineer of the Miami and Erie Canal, investigated repairs to the canal by direction of the General Assembly, that body having requested an estimate of the cost of repairs and an opinion on whether the canal should be abandoned. He submitted a report to the State Board of Public Works which estimated $31,613, would be needed to repair the Warren County Canal. Of that sum, $16,896 was needed just for dredging. Because the canal had been little used, the State declined to repair it. In the General Assembly, Representative Durbin Ward of Lebanon introduced legislation to abandon the "Lebanon Ditch." In 1854, the state sold the remnants for $40,000 to John W. Corwin and R.H. Henderson. The large stones of the locks were used in local buildings, especially the Lebanon Opera House, which burned on Christmas Day, 1932 and occupied the site of the present Lebanon City Hall at Broadway and Main Street. Other stones were used in the bridge across the North Fork. The reservoir on the North Fork of Turtle Creek collapsed in a violent rainstorm on July 10, 1882, causing much damage in Lebanon, including washing out the bridge on Broadway over Turtle Creek.
