Upper Field 14 Reservoir dam
Upper Field 14 Reservoir
Located in Honokowai, Maui, Hawaii, the Upper Field 14 Reservoir, also known as the Honolua Reservoir, is a privately owned water resource managed by the USDA NRCS. Constructed in 1985, this earth dam stands at a height of 38 feet and has a storage capacity of 18.1 acre-feet, primarily used for irrigation purposes. With a surface area of 1.1 acres and a normal storage of 17 acre-feet, this reservoir plays a crucial role in supporting agricultural activities in the area.
Despite its fair condition assessment and high hazard potential, the Upper Field 14 Reservoir remains under the regulatory supervision of the Hawaii Department of Land and Natural Resources. The dam has a moderate risk level, with a spillway type classified as uncontrolled and a maximum discharge capacity of 100 cubic feet per second. Regular inspections are conducted every five years, with the last assessment carried out in May 2020, ensuring the safety and stability of this essential water storage infrastructure for the local community.
With its picturesque setting and vital role in sustaining irrigation activities in Maui, the Upper Field 14 Reservoir serves as a significant water source in the region. As water resource and climate enthusiasts, understanding the importance of maintaining and monitoring such structures is crucial for ensuring the continued supply of water for agricultural purposes and safeguarding the surrounding environment from potential risks associated with dam failure.
Dam data reference
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 Upper Field 14 Reservoir
Where does the data for Upper Field 14 Reservoir 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.
