Stockpond dam
Stockpond
Stockpond, located in Antelope Coal Mine, Campbell County, Wyoming, serves multiple purposes such as flood risk reduction, fire protection, and as a stock or small fish pond. Constructed in 2007, this earth dam stands at a height of 28 feet with a hydraulic height of 20 feet, providing a storage capacity of 165 acre-feet. With a surface area of 12 acres and a drainage area of 1 square mile, Stockpond plays a vital role in managing water resources in the region.
Managed by a private owner, Stockpond is regulated by the State of Wyoming with oversight from the State Engineer's Office and Department of Environmental Quality. The dam's condition assessment in 2017 rated it as fair with a low hazard potential. Despite its moderate risk level, Stockpond has a history of meeting inspection and enforcement requirements, ensuring its structural integrity and safety. With Liz Cheney as the Congressional Representative for the area, Stockpond remains a key asset for water storage and flood mitigation efforts in the region.
Incorporating stone core types and soil foundations, Stockpond's uncontrolled spillway and other controlled outlet gates help manage water discharge effectively. The dam's last inspection in July 2017 revealed its operational adequacy with a prescribed frequency of every 5 years. As an essential infrastructure for water management and conservation, Stockpond serves as a testament to sustainable water resource practices while addressing the challenges of climate change in Wyoming's arid landscape.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Stockpond
Where does the data for Stockpond 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.
