Pond No. 1 At Kauai Ranch dam
Pond No. 1 At Kauai Ranch
Pond No. 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.
- 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.
- 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.
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, environmental 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.

About Pond No. 1 At Kauai Ranch
Where does the data for Pond No. 1 At Kauai Ranch come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the High hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
