Summary
Built in 1917, this earth dam stands at a height of 25 feet and has a capacity to hold 260 acre-feet of water for irrigation purposes. With a surface area of 20.8 acres and a drainage area of 0.08 square miles, the reservoir is fed by an irrigation ditch and is regulated by the Hawaii Department of Land and Natural Resources.
Despite its age, Maui Reservoir 60 is in fair condition with a high hazard potential, prompting regular inspections and a moderate risk assessment score of 3. The dam has a controlled spillway with a width of 4 feet and an unlisted foundation type. With a recent inspection date in July 2020 and a condition assessment conducted in April 2021, the reservoir is equipped with emergency action plans and meets state regulatory requirements for operation, inspection, and enforcement.
For water resource and climate enthusiasts, Maui Reservoir 60 serves as a vital water storage infrastructure supporting irrigation in the region. As one of many dams in Hawaii, its historical significance and ongoing maintenance efforts highlight the importance of sustainable water management practices in the face of changing environmental conditions. With the potential to mitigate water scarcity challenges and enhance agricultural productivity, this reservoir showcases the intersection of water resource management, infrastructure resilience, and climate adaptation in a tropical island setting.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
