Jug Creek Upper dam
Jug Creek Upper
Jug Creek Upper, also known as Upper Jug Creek Reservoir, is a privately owned dam located in Valley, Idaho. Completed in 1946, this earth dam stands at a height of 32.3 feet and has a maximum storage capacity of 1132 acre-feet. With a primary purpose of irrigation, the dam serves the surrounding area with water from Jug Creek and Louie Creek.
The reservoir covers an area of 85 acres and has a controlled spillway with a width of 20 feet. It has a significant hazard potential and is classified as being in fair condition as of the last assessment in July 2019. The dam is regularly inspected by state authorities and meets permitting, inspection, and enforcement requirements. In case of emergencies, the dam is equipped with an emergency action plan to ensure the safety of downstream communities.
Located within the Walla Walla District, Jug Creek Upper plays a crucial role in water resource management in the region. With its very high risk assessment rating, the dam is closely monitored to mitigate any potential hazards and ensure the continued reliability of its irrigation functions. For water resource and climate enthusiasts, Jug Creek Upper represents a fascinating intersection of infrastructure, sustainability, and natural resource management in the beautiful landscape of Idaho.

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 Jug Creek Upper
Where does the data for Jug Creek Upper 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.
