Hulet No 2 Dam dam
Hulet No 2 Dam
Hulet No 2 Dam, located in Owyhee County, Idaho, was completed in 1987 for the primary purpose of irrigation. This private-owned earth dam stands at a height of 55.3 feet and has a hydraulic height of 51.2 feet. With a storage capacity of 6,770 acre-feet and a surface area of 347 acres, the dam plays a crucial role in water resource management in the region.
The dam, constructed with stone core and rock-soil foundations, spans a length of 2,400 feet and features an uncontrolled spillway with a width of 27 feet. While the hazard potential is considered significant, the condition assessment as of May 2018 deemed the dam to be in fair condition. Regular inspections are conducted, with the last one taking place in May 2018 with a frequency of every 4 years. The risk assessment categorizes the dam's risk as moderate, indicating the need for ongoing risk management measures to ensure the safety and integrity of the structure.
Hulet No 2 Dam serves as a vital infrastructure for water supply and irrigation in the area, contributing to agricultural activities and water resource sustainability. With its strategic location on an unnamed stream that feeds into the Snake River, the dam plays a crucial role in managing water flow and storage. Climate and water resource enthusiasts can appreciate the engineering and operational aspects of this dam, along with the ongoing efforts to maintain its safety and functionality for the benefit of the local community and environment.

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 Hulet No 2 Dam
Where does the data for Hulet No 2 Dam 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 Significant 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.
