The dam has a significant hazard potential and is rated as being in fair condition. It is equipped with a controlled spillway and a single valve outlet gate for water release. The last inspection of the dam was conducted in October 2011, with an inspection frequency of every 3 years. Despite its age, the dam is considered to have a very high risk potential, emphasizing the importance of regular maintenance and monitoring to ensure its continued effectiveness in flood risk reduction.
