Mt. Ida Dam Project


  • August 2nd, 2019 | PDF

On September 28, 2018, following an emergency engineering inspection, the Mount Ida Lake Dam was identified as structurally unsound. To comply with NYS Department of Environmental Conservation dam safety regulations, the City will remove of a section of the dam to alleviate immediate structural concerns. This will result in the Poesten Kill creek water level being lowered to the creek bed. Belden Pond/ Ida Lake is also expected to experience reductions in water level.
