Little Sage Creek Reservoir dam
Little Sage Creek Reservoir
Little Sage Creek Reservoir, located in Carbon County, Wyoming, is a federally owned gravity dam primarily designed for debris control on the Little Sage Creek. Completed in 1969 by the Bureau of Land Management, this reservoir has a structural height of 26 feet and a hydraulic height of 21 feet, with a storage capacity of 380 acre-feet and a surface area of 132.3 acres. The dam is regulated by the State of Wyoming and inspected regularly to ensure its satisfactory condition.
Despite its relatively small size, Little Sage Creek Reservoir poses a high hazard potential due to its location and design. The reservoir has an uncontrolled spillway and no outlet gates, making it crucial for emergency preparedness and risk management. The dam is classified as having a moderate risk level, requiring ongoing monitoring and potential mitigation measures to prevent any potential disasters.
Local water resource and climate enthusiasts can appreciate Little Sage Creek Reservoir for its role in maintaining water quality and managing debris along the creek. The dam's purpose and design reflect the importance of balancing environmental conservation with infrastructure development, showcasing the complexities involved in managing water resources in a changing climate. As a federally owned structure, the reservoir serves as a critical asset for the Bureau of Land Management and highlights the ongoing efforts to ensure the safety and sustainability of water infrastructure in Wyoming.

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 Little Sage Creek Reservoir
Where does the data for Little Sage Creek Reservoir 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.
