Wagon Prong Dam dam
Wagon Prong Dam
Wagon Prong Dam, located in Washakie, Wyoming, is a gravity dam primarily used for water supply. Built in 2003 by the Bureau of Land Management, this federal-owned structure stands at a height of 36 feet with a hydraulic height of 30 feet. With a storage capacity of 42.9 acre-feet and a surface area of 3.9 acres, the dam serves the West Fork Hampton Draw and Big Ho River or stream.
Despite its low hazard potential and fair condition assessment, Wagon Prong Dam is subject to regular state inspections, enforcement, and permitting to ensure its safety and compliance with regulations. The Omaha District of the US Army Corps of Engineers oversees its operations, while the Bureau of Land Management is responsible for its design, construction, regulation, and inspection. With a risk assessment rating of 2 (high), the dam's risk management measures are crucial in mitigating potential threats and ensuring the safety of surrounding communities in case of emergencies.
As a key water resource infrastructure in Wyoming, Wagon Prong Dam plays a vital role in providing water supply to the region. Its construction and maintenance are essential for sustaining the local ecosystem, agriculture, and residential needs. With its strategic location and federal ownership, the dam represents a significant asset in managing water resources and addressing the challenges posed by climate change in the area.

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 Wagon Prong Dam
Where does the data for Wagon Prong Dam 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.
