Ashley Valley Flood Control dam
Ashley Valley Flood Control
The Ashley Valley Flood Control structure, located in Uintah, Utah, is a privately-owned dam designed to reduce flood risks in the area. Regulated by the Utah Division of Water Rights, this earth dam has a hydraulic height of 61 feet and a structural height of 69 feet, providing storage of up to 4100 acre-feet of water. The dam is associated with a tributary to Ashley Creek and serves the primary purpose of flood risk reduction.
With a low hazard potential and a condition assessment that is currently not rated, the Ashley Valley Flood Control structure undergoes inspections every five years to ensure its safety and effectiveness. The last inspection was conducted in August 2017. Although the dam does not have an Emergency Action Plan (EAP) prepared at this time, it meets regulatory guidelines for state jurisdiction and enforcement. The dam's location and design play a crucial role in mitigating flood risks and protecting the surrounding area from potential inundation events.
Overall, the Ashley Valley Flood Control structure stands as a vital asset in managing water resources and climate-related risks in the region. With its capacity for flood risk reduction and storage capabilities, this privately-owned dam plays a key role in safeguarding the community from potential flooding events. As it continues to be regulated and inspected by the appropriate authorities, the dam remains a crucial part of the water infrastructure in Uintah, Utah.
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 Ashley Valley Flood Control
Where does the data for Ashley Valley Flood Control 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 Low 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.
