The dam's risk assessment is moderate, indicating a potential for significant consequences in the event of failure. Managed by private owners, the reservoir's emergency action plan is currently under review, underscoring the importance of ensuring the safety and integrity of this critical water resource infrastructure in the face of climate variability and changing precipitation patterns.
Located in a region vulnerable to the impacts of climate change, Maui Reservoir 15 serves as a significant water source for irrigation in the area, highlighting the need for ongoing maintenance and risk management measures to safeguard against potential hazards and ensure the sustained availability of water resources for agricultural use in the face of evolving environmental conditions.
