Buchanan city officials say a weir would allow more water to flow down McCoy Creek and into Peers Mills, one of Buchanan's most historic locations.
However, some people with Friends of McCoy Creek are concerned that changing the water's flow could ruin the natural habitat.
Scott King is an avid trout fisherman and for years has helped keep McCoy Creek clean.
King says a weir would force too much water through the creek, pushing natural sediment through the waterway.
He is also concerned that a weir could destroy the natural habitat that trout and salmon live within.
King thinks the city should consider other ways of bringing water to the mill.
Meantime, the city manager says they have been exploring different options for years.
Aside from bringing the mill to life, she says changing the creek flow would also help get rid of standing water, a breeding ground for mosquitoes and the West Nile Virus.
“We would never do anything to harm the creek and we are going to watch this and monitor it very carefully to make sure it doesn't have a negative impact,” says Meg Mullendore, City Manager of Buchanan.
“Instead of a fine trout and salmon stream, you're going to have a ditch carrying dirt. Sediment is right up there with untreated sewage, as a cause for devastation to a trout stream,” says Scott King, past president of Friends of McCoy Creek.
The city of Buchanan is still applying for a permit to do work on the creek, so nothing is set in stone.
Thursday night (June 14th), residents have a chance to voice their concerns about the a potential weir on the creek.
Michigan's Department of Environmental Quality or DEQ is hosting a meeting at 7 pm at Buchanan's City Hall.
The public is welcome and encouraged to attend.
