John Arambel dam
John Arambel
John Arambel is a private water resource located in Sublette, Wyoming, near the JONAH GULCH stream. This earth dam serves multiple purposes including fire protection, stock watering, and small fish pond management. With a structural height of 22 feet and a storage capacity of 728 acre-feet, this dam plays a crucial role in water management in the region. It has a low hazard potential and is in fair condition, last inspected in September 2021.
Owned privately, John Arambel is regulated by the Wyoming State Engineer's Office and undergoes regular inspections and enforcement to ensure its safety and functionality. The dam features a slide gate outlet and an uncontrolled spillway with a width of 54 feet. It has a moderate risk assessment rating of 3, highlighting the importance of proper risk management measures. Despite its remote location, this dam plays a vital role in supporting local fire protection efforts and providing water for livestock and wildlife.
Situated in Congressional District 00 in Wyoming, John Arambel stands as a testament to the importance of sustainable water resource management in arid regions. With a drainage area of 34.66 square miles and a maximum discharge of 1315 cubic feet per second, this dam plays a crucial role in regulating water flow and providing essential services to the local community. As climate change impacts water resources, the maintenance and proper management of structures like John Arambel become increasingly important for ensuring water security and resilience in the face of environmental challenges.

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 John Arambel
Where does the data for John Arambel 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.
