The city of New Albany is taking steps to protect a historic dam.The city is filing a lawsuit to prevent the removal of the Glenwood Park Dan, also known as the Providence Mill Dam. The dam is located on Silver Creek.The removal is part of the plans for the 400-acre Origin Park, and the city says if the park removes the dam, it would cost nearly $2 million to replace it. According to Mayor Jeff Gahan, the dam is important in providing water supply for fish and wildlife, flood protection, and water levels for recreational opportunities.The lawsuit claims the city owns the rights to the dam and is challenging the River Heritage Conservancy and Ecosystems Connections Institute's lack of necessary approval.
