Hog Park Main Dam dam
Hog Park Main Dam
Hog Park Main Dam, located in Carbon County, Wyoming, along the Hog Park Creek, serves as a vital water supply infrastructure for the city of Encampment. Built in 1986, this earth dam stands at a height of 118 feet and has a storage capacity of 24,987 acre-feet, primarily used for irrigation, fish and wildlife ponds, and water supply purposes. Its spillway, with a width of 10 feet, is uncontrolled, allowing for a maximum discharge of 1,400 cubic feet per second.
Managed by the local government and regulated by the Wyoming State Engineer's Office, Hog Park Main Dam is considered to have a high hazard potential due to its location and design. Despite its high-risk status, the dam has a moderate risk assessment score of 3, indicating that it is adequately managed and meets safety guidelines. The dam underwent its last inspection in July 2021, with a scheduled inspection frequency of every 5 years to ensure its structural integrity and safety measures are up to date.
For water resource and climate enthusiasts, Hog Park Main Dam presents an intriguing case study of a critical infrastructure project in a rural setting, balancing the needs of water supply, irrigation, and environmental conservation. With its designer, Floyd A. Bishop, overseeing its construction, the dam continues to play a significant role in supporting the local community's water needs while maintaining a careful balance between human development and ecological sustainability in the region.

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 Hog Park Main Dam
Where does the data for Hog Park Main 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 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.
