The 1913 Gorge Waterfall (First Energy Dam) in Cuyahoga Falls - 5.6.2023

A brief History of the dam (From Wikipedia)

Gorge Metropolitan Park Dam

The largest dam is the Gorge Metropolitan Park Dam, also known as the FirstEnergy Dam, on the border between Cuyahoga Falls and Akron. This 57-foot (17 m) dam has for over 100 years submerged the falls for which the City of Cuyahoga Falls was named; more to the point of water quality, it has created a large stagnant pool with low dissolved oxygen.
The FirstEnergy Dam was built by the Northern Ohio Traction and Light Co. in 1912 to serve the dual functions of generating hydropower for its local streetcar system and providing cooling-water storage for a coal-burning power plant; however, the hydropower operation was discontinued in 1958, and the coal-burning plant was decommissioned in 1991.

Some environmental groups and recreational groups want the dam removed.Others contend that such an effort would be expensive and complicated, for at least two reasons: first, the formerly hollow dam was filled in with concrete in the early 1990s, and second, because of the industrial history of Cuyahoga Falls, the sediment upstream of the dam is expected to contain hazardous chemicals, possibly including heavy metals and PCBs. The Ohio EPA estimated removal of the dam would cost $5–10 million, and removal of the contaminated sediments, a further $60 million.The dam is licensed through 2041.

On April 9, 2019, officials from the U.S. EPA and Ohio EPA announced a plan to remove the Gorge Metropolitan Park Dam by 2023 at a cost of $65 to $70 million. Funding for the project was authorized through the Great Lakes Legacy Act with funds coming from the City of Akron and members of the Gorge Dam Stakeholder Committee, including Summit Metro Parks, FirstEnergy, and the City of Cuyahoga Falls. As of 2022 the planned date of removal is 2026.
