Andy Capp dam
Andy Capp
Andy Capp, located in Culbertson, Montana, is a privately owned earth dam built in 1949 for multiple purposes including fire protection, stock, and small fish pond. With a dam height of 12 feet and a capacity of 206 acre-feet, this low hazard potential structure on TR-Sheep Creek is regulated by the Montana Department of Natural Resources and Conservation (DNRC). The dam serves as a vital resource for the local community and surrounding areas, ensuring water availability for various needs.
Despite its age, Andy Capp remains in good condition and has not been rated for its structural integrity. The dam's primary purpose of fire protection and water storage contributes to its significance in the region, providing essential resources for both human and ecological needs. With state jurisdiction and regulatory oversight in place, the dam is regularly inspected and maintained to ensure its continued functionality and safety.
As a key feature in the water resource infrastructure of Roosevelt County, Montana, Andy Capp plays a crucial role in water management and conservation efforts. Its strategic location and purposeful design make it a valuable asset for mitigating potential risks and safeguarding water resources in the area. For water resource and climate enthusiasts, Andy Capp serves as a fascinating example of how private dams contribute to ecosystem resilience and community well-being in a changing climate.

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 Andy Capp
Where does the data for Andy Capp 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.
