Wanship dam
Wanship
Wanship is a Federal-owned irrigation dam located in Coalville, Utah, along the Weber River. Completed in 1957 by the Bureau of Reclamation, this Earth dam stands at a structural height of 175 feet and has a hydraulic height of 150 feet. With a storage capacity of 75,730 acre-feet and a normal storage of 62,120 acre-feet, Wanship serves as a crucial water resource for the surrounding area, covering a surface area of 1,077 acres.
This dam plays a vital role in water management and irrigation in Summit County, Utah, providing essential water supply for agricultural purposes. Despite its high hazard potential, the condition assessment of Wanship is currently not available, highlighting the need for regular inspections and maintenance to ensure its structural integrity and safety. The Emergency Action Plan (EAP) for the dam was last revised in September 2020, emphasizing the importance of preparedness and risk management in the event of an emergency.
As an integral part of the water infrastructure in the region, Wanship dam's significance lies in its contribution to water supply sustainability and management in an area prone to climate variability. Climate enthusiasts and water resource experts alike recognize the importance of maintaining and monitoring structures like Wanship to safeguard water resources and mitigate potential risks associated with dam failure.

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 Wanship
Where does the data for Wanship 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 High 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.
