Niagara Gorge Discovery Center

The Schoellkopf Power Station was built on land owned by Jacob F. Schoellkopf above the Niagara Gorge near the American Falls, 1,600 feet (490 m) downriver from Rainbow Bridge. Understanding the growing need for electricity and the role of harnessing the Falls, Schoellkopf purchased the land for the hydraulic canal on May 1, 1877 for $71,000. After Schoellkopf Sr.'s death in 1903, his sons took over the operation of the power business. In 1918, Schoellkopf's Niagara Falls Hydraulic Power and Manufacturing Company merged with the Niagara Falls Power Company, which was owned by Edward Dean Adams. Much of the site is, as of 2014, occupied by the Maid of the Mist tour boat company as a maintenance area and off-season boat storage yard. The power station remains form a part of a fully accessible tourist attraction associated with Niagara Falls State Park and is connected with its Niagara Gorge hiking trail system.
