Wellsville dam
Wellsville
Wellsville, located in Cache County, Utah, is home to a significant irrigation dam known as the Wellsville Dam. Constructed in 1957, this earth dam stands at a structural height of 25 feet and has a hydraulic height of 24 feet, providing essential water storage for agricultural purposes in the region. The dam has a storage capacity of 50 acre-feet and is situated on the East Spring Stream, serving as a vital resource for the surrounding community.
Managed by the Utah Division of Water Rights, the Wellsville Dam is regulated, inspected, and enforced to ensure its safety and functionality. Although the condition assessment is currently marked as "Not Rated," the dam's hazard potential is classified as significant, highlighting the importance of ongoing monitoring and maintenance. With a regular inspection frequency of every two years, the dam plays a crucial role in water resource management and supports sustainable irrigation practices in the area.
Despite the lack of specific details on spillways, drainage areas, or risk assessments, the Wellsville Dam remains a key infrastructure for water storage and distribution in Cache County. As climate change continues to impact water resources, the efficient operation and maintenance of dams like Wellsville are essential in ensuring the resilience of agricultural systems and the availability of water for future generations.

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 Wellsville
Where does the data for Wellsville 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.
