Dam Removal Looks To Improve Water Quality And Economy
Improving water quality for fish and other wildlife is the goal of a one-million dollar project to remove two river dams in the city of Cuyahoga Falls this summer. Supporters believe taking down the dams will also improve the quality of life for local residents and boost the local economy. ********
The sound of water pouring over the Sheraton dam in Cuyahoga Falls â is about to become history. And that gives Bill Zawiski a sense of accomplishment.
Itâs going to be neat, people are going to be here and itâs going to be fun.
Zawiski is a biologist with the Ohio Environmental Protection Agency. Heâs been working for 15-years to get the dams torn down. Zawiski is standing on a deck overlooking the 11-foot high dam on the Cuyahoga River at the riverside Sheraton hotel in the heart of Cuyahoga Falls. Upstream, just out of sight, is the Le Fever dam, also slated for demolition. Both were built beginning in 1914 to power paper, rubber, copper and steel mills that are long gone. Zawiski says dams and the slow-moving pools they create are a serious problem for fish and the aquatic insects they feed on. "The water thatâs underneath the flowing water on top loses oxygen. So you have this devoid area of oxygen and when it gets, we call it anoxic, it can have different chemicals like hydrogen sulfide. And those chemicals are toxic to aquatic life." And so these dams are coming down. But not all at once. "Weâre going to drop in a barge thatâs going to float a track-hoe machine, similar to an excavator that youâd see digging a ditch," says Joel Bingham, aquatic biologist with EnviroScience, the company hired to do the demolition. "Itâs going to use a special attachment, a jack hammer attachment," Bingham says. "Weâre going to float that barge down to the dam and stabilize it with cables and other devices. And weâre going to start chipping away at the dam. Bingham says sediments behind the dams have been tested for contaminants and judged safe for release to the river. While the old powerhouse structures on the west side of the Sheraton dam will remain, both dams will be completely removed. And Cuyahoga Falls city engineer Tony Demasi says that will change the flow â and the look - of the river.
Everyone in the city has always seen a dam in the river. They donât remember a time when the dam wasnât there. And so thereâs some anticipation, thereâs some curiosity and so we try to help people along with that process and assure them that the final product is going to be what nature intended this river to be anyway.
What nature intended is lower water levels that fluctuate with the seasons. Downstream of the two dams, the Cuyahoga races through a narrow sandstone gorge over bedrock and boulders, churning the river into white water. Some kayakers have already been braving the falls for this white water experience. Cuyahoga Falls Mayor Don Robards says in recent years, the city has seen major development of new housing and shops along the riverâs edge. But with the dams removed - at no cost to the city thanks to a grant from the Ohio EPA - he also expects an increase in river recreation and tourism. "The kayaking and rafting for this are are unique, because theyâre saying, once you hit this area right here, theyâre rating it as potentially a Class 4, Class 5," Robards says. "The next area is down in West Virginia. So we see people from all of Northeast Ohio and maybe beyond, theyâre going to be staying overnight, theyâre going to want to kayaking and canoeing and those kinds of thing here, because of the treacherous terrain." "But it wonât all be treacherous. In recent years, Cuyahoga Falls has built new riverside boardwalks, paths, and several parks that get people closer to the river. Ohio EPAâs Bill Zawiski says the new dam-free Cuyahoga will be even more user-friendly. "In this area between the two structures, really Broad Street to Portage Trail, the river will be wade-able and I anticipate people will probably walk in there. I do." Heavy rains have delayed removal of the dams in Cuyahoga Falls, but demolition is finally underway. People can watch on a city web cam or come to watch in person as the dams come down.
