Homeowners fear their lakefront property will be underwater if they don't.
"It will wipe us out," said David Bell, Greece.
David Bell has lived on Lake Ontario for 14 years. He fears not only his view, but his entire home, will be washed away if the agency that oversees water levels has its way.
"Since 1958, they've agreed to keep the lake as it is. We can deal with that . But to increase the water levels by a foot, seasonally, would absolutely destroy everything you see here," said Bell.
The International Joint Commission wants to adopt "Plan 2014" allowing it to raise and lower lake levels as it wishes.
"This is, this is it for me, ya know," said Stephen Fritsch, Greece.
Stephen Fritsch has lived here 35 years.
"Right now I have a beach. But I mean, it's come up right up to the water. I mean. It's come up to the edge here. At times. So you've got to keep an eye on it. Right now it looks heavenly," said Fritsch.
Nearly 1,000 other homeowners like David and Stephen, as well as the town of Greece, are fighting the plan.
"I don't support the plan because I think it elongates the periods of time when the water is at the highest and the lowest. What that means is with our unpredictable weather that we've seen in recent years, with the water being at the high level, for a longer period of time, it's more likely to have a severe storm. Causing tremendous damage," said Bill Reilich, Greece Town Supervisor.
The plan to regulate the lake levels along the shores of Lake Ontario may not sit well with homeowners, but environmentalists say it's necessary to protect the lake's natural habitat.
"There is no way this this habitat is going to improve by increasing the water levels. It's only going to flood the wetlands. It's going to increase the destruction of everything we have," said Bell.
David says he's fighting to protect his habitat.
Homeowners are hoping the plan gets push back in Washington. There is no timetable for either the U.S. or Canadian governments to take action on the plan.
