Ashley Twin Lakes dam
Ashley Twin Lakes
Ashley Twin Lakes, located in Uintah, Utah, is a privately owned water resource managed by the Utah Division of Water Rights. Built in 1920 for irrigation purposes, this earth dam stands at a structural height of 17 feet and has a hydraulic height of 14 feet. The reservoir has a storage capacity of 450 acre-feet and serves as a critical water source for agricultural activities in the region.
Situated along the South Fork of Ashley Creek, Ashley Twin Lakes plays a vital role in water management and distribution in the area. Despite being an older structure, the dam's hazard potential is considered significant, emphasizing the importance of regular inspections and maintenance. With a history dating back over a century, the reservoir continues to support the local community's water needs while also contributing to the overall ecological balance of the surrounding area.
Owned by private entities, Ashley Twin Lakes operates under the jurisdiction of state regulatory agencies, ensuring compliance with safety and environmental standards. With a distance of 20 miles from Vernal, this reservoir stands as a testament to sustainable water resource management practices in the state of Utah. As water resource and climate enthusiasts, understanding the significance of structures like Ashley Twin Lakes is crucial in appreciating the intricate balance between human needs and natural ecosystems in the face of a changing climate.
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 Twin Lakes
Where does the data for Ashley Twin Lakes 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.
