While the dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment, it is regulated by the New York State Department of Environmental Conservation (NYS DEC). The dam underwent its last inspection in November 2020, with inspections conducted every 4 years. Despite its moderate risk level, the dam does not currently have an Emergency Action Plan in place, highlighting the need for further risk management measures to ensure the safety and integrity of the structure.
