Padlock No. 1 A Five Mile dam
Padlock No. 1 A Five Mile
Padlock No. 1 A Five Mile, located in Ranchester, Wyoming, is a privately owned earth dam constructed in 1961 for the primary purpose of irrigation. This dam, standing at a height of 36 feet and with a structural height of 40 feet, impounds Five Mile Creek, creating a reservoir with a normal storage capacity of 536 acre-feet. The dam has a spillway width of 140 feet and a maximum discharge capacity of 8,561 cubic feet per second.
Despite being classified as having a high hazard potential, Padlock No. 1 A Five Mile is currently in fair condition and is inspected every five years to ensure its structural integrity. The dam is regulated and permitted by the Wyoming State Engineer's Office, with all necessary inspections and enforcement measures in place. With a risk assessment rating of moderate, this dam plays a crucial role in providing water for irrigation purposes while also serving for fire protection, stock watering, and small fish pond habitats in the area.
Overall, Padlock No. 1 A Five Mile is an essential water resource infrastructure in Sheridan County, Wyoming, ensuring water supply for agricultural activities and other uses in the region. As a part of the broader network of dams in the area, this structure highlights the importance of proper maintenance and regulatory oversight to mitigate potential risks and ensure the safety and reliability of water resources in the face of changing climate conditions.
Dam data reference
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 Padlock No. 1 A Five Mile
Where does the data for Padlock No. 1 A Five Mile 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.
