īetween March 16 and 21, 1936, the tributaries of the Allegheny and Monongahela Rivers including the Conemaugh flooded as a result of heavy rainfall and melting snow and ice. The Johnstown Flood of 1889 rendered the Juniata Branch of the Pennsylvania Canal useless, stranding the Western Division from commerce in the east canal towns, such as Livermore, began a steady decline. It had one school that served thirty-two students. In 1906, the town had several stores and three churches with Presbyterian, Methodist, and United Brethren congregations. A more solid brick structure was built in 1862. The first church structure was a frame that the Baptists and Presbyterians shared. The Livermore Presbyterian Church was organized in 1851, though the congregation seldom met for lack of supplies, and ministers frequently shared time between Livermore and the congregation in nearby Salem. On February 13, 1865, the town was incorporated as a borough within the township, by the county courts. With the growth of the canal, the town increased slightly. These tracks were used for 25 years until 1907, when a new straight line bypassed the canal curves. Another grade was built in 1882 to bypass a hill. Grading from Blairsville to the Allegheny River was completed in 1857, and the same year, the state sold the canal to the Pennsylvania Railroad. The West Penn Railroad extended past Livermore alongside the canal in 1854, and a station was built in 1864, providing connections to Blairsville and Saltsburg. The Main Line Canal's Western Division, which stretched 103 miles from Johnstown to Pittsburgh, was constructed past Livermore along the Conemaugh. The Pennsylvania legislature had established the Board of Canal Commissioners for the Commonwealth in 1825, and authorized a public canal and railroad project across the state, the Pennsylvania Canal system. The town was established along the Conemaugh River within Derry Township in 1827 by John Livermore, naming the town after himself. History Map of Livermore published in the Westmoreland County Atlas, 1876 Much of the former town site now lies under the reservoir and floodplains. The town was abandoned and partially razed in the early 1950s following authorization by the Flood Control Act of 1936 and Flood Control Act of 1938 for construction of the Conemaugh Dam and Lake to prevent flooding of Pittsburgh. Livermore, Pennsylvania is an abandoned town that was located on the Conemaugh River between Blairsville and Saltsburg in Derry Township, Westmoreland County, Pennsylvania.
