Big Horn Dike A dam
Big Horn Dike A
Big Horn Dike A, also known as Dike A, is a vital earth dam located in Johnson, Wyoming, specifically in the city of Beckton along Cross Creek. Completed in 1964, this privately owned structure serves primarily for irrigation purposes, providing crucial water resources for the surrounding area. With a dam height of 45 feet and a length of 775 feet, Big Horn Dike A has a storage capacity of 5756 acre-feet, making it a significant contributor to water management in the region.
Despite its age, Big Horn Dike A is in fair condition and has a high hazard potential, indicating the importance of regular inspections and maintenance. The dam's spillway, an uncontrolled type with a width of 40 feet, has a maximum discharge capacity of 4756 cubic feet per second. Emergency action plans have been prepared, and the structure meets regulatory guidelines, ensuring that risks are managed effectively. With its critical role in irrigation and water storage, Big Horn Dike A stands as a key asset in supporting the local ecosystem and agricultural activities in the area.
As a noteworthy feature in the water resource infrastructure of Wyoming, Big Horn Dike A serves as an essential component in the management of water resources for irrigation purposes. With its significant storage capacity, fair condition, and high hazard potential, this earth dam plays a crucial role in ensuring water availability and safety for the surrounding community. By meeting regulatory standards and having emergency preparedness measures in place, Big Horn Dike A exemplifies responsible stewardship of water resources in the region, highlighting the importance of sustainable water management practices for climate enthusiasts and water resource professionals alike.

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 Big Horn Dike A
Where does the data for Big Horn Dike A 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.
