Summary

1 at Kauai Ranch is a privately owned irrigation pond located in Kapaa, Hawaii. Built in 2004, this earth dam structure stands at a height of 31.5 feet and has a storage capacity of 25.8 acre-feet, serving the primary purpose of irrigation. With a surface area of 2.8 acres and a drainage area of 0.02 square miles, this pond plays a crucial role in supporting agricultural activities in the region.

Despite its relatively small size, Pond No. 1 has a high hazard potential and is classified as having a fair condition assessment. The dam features an uncontrolled spillway with a width of 70 feet, and it is regulated, inspected, and enforced by the Hawaii Department of Land and Natural Resources. The last inspection took place in December 2018, with an inspection frequency of every 5 years. In the event of an emergency, the pond's Emergency Action Plan (EAP) readiness and risk management measures are currently being assessed to ensure the safety of the surrounding area.

With its strategic location and vital function in supporting local agriculture, Pond No. 1 at Kauai Ranch stands as a testament to responsible water resource management in the face of climate challenges. As enthusiasts of water resources and climate resilience, it is important to monitor and support the ongoing maintenance and safety measures of such key infrastructure to ensure sustainable water management practices for future generations.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
