Situated on Panther Creek, Pinestone Lake Dam has a spillway type of "Uncontrolled" with a spillway width of 57 feet. The dam covers a surface area of 11.94 acres and has a drainage area of 0.65 square miles. Although it has a hazard potential rated as "High", the condition assessment as of July 2008 was deemed "Fair", with a moderate risk level of 3. Regular inspections are conducted every two years to ensure the safety and integrity of the dam. While the dam is not owned or funded by any federal agency, it is regulated and permitted by the Indiana Department of Natural Resources (IDNR).
In the event of an emergency, the dam does not have an Emergency Action Plan (EAP) in place, and there are no inundation maps prepared. Despite the moderate risk associated with Pinestone Lake Dam, appropriate risk management measures are yet to be detailed. With its significant role in water supply and recreation, continued monitoring and maintenance of this dam are essential to safeguard the surrounding community and environment from potential hazards.
