Notes
Survey number HAER WV-30
Building/structure dates: 1926 initial construction
Significance: When built, the Lake Lynn power house and dam reflected the state of the art in American hydroelectric power technology and developed a very substantial portion of West Virginia's hydrologic resources. This utility helped provide electricity to much of northern West Virginia and southwestern Pennsylvania and encouraged economic development in these areas. The reservoir created by the dam also permits the Monongahela River (into which the Cheat River flows) to run normally during dry, late summer months.
