Jim Bridger Power Plant Surge Pond dam
Jim Bridger Power Plant Surge Pond
The Jim Bridger Power Plant Surge Pond, located in Point of Rocks, Wyoming, serves as a crucial water supply structure designed by D.G. McMillen in 1989. This Earth dam, standing at a height of 51 feet and a structural height of 97 feet, plays a significant role in storing water from the Humphrey Draw river for various purposes, including water supply. With a storage capacity of 2228 acre-feet, this reservoir covers a surface area of 96 acres and has a drainage area of 3.6 square miles.
Despite its fair condition assessment and significant hazard potential, the Jim Bridger Power Plant Surge Pond operates under the oversight of the Wyoming State Energy Office, ensuring that it meets regulatory standards for inspection, permitting, and enforcement. The uncontrolled spillway, with a width of 12 feet, allows for a maximum discharge of 140 cubic feet per second in case of emergencies. While the dam's risk assessment is moderate, ongoing risk management measures are in place to mitigate potential hazards and ensure the safety of the surrounding area.
As a vital component of the water infrastructure in Sweetwater County, Wyoming, the Jim Bridger Power Plant Surge Pond stands as a testament to the importance of sustainable water resource management in the face of a changing climate. Its role in providing water supply to the region underscores the need for continued monitoring, maintenance, and risk assessment to safeguard both the structure and the communities it serves.

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 Jim Bridger Power Plant Surge Pond
Where does the data for Jim Bridger Power Plant Surge Pond 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.
