Despite its low hazard potential, the dam is currently in poor condition as of the last inspection in July 2019. The spillway is uncontrolled with a width of 25 feet, and the outlet is equipped with a single valve.

With a moderate risk assessment rating of 3, Sundby is facing challenges due to its poor condition and lack of recent updates or improvements. The dam's emergency action plan (EAP) status and risk management measures are unclear, raising concerns about its ability to withstand potential emergencies or natural disasters. As water resource and climate enthusiasts, it is crucial to monitor and address the maintenance and safety of Sundby to ensure the protection of surrounding areas and the efficient management of water resources in the region.
