Bill Leavitt Reservoir dam
Bill Leavitt Reservoir
Bill Leavitt Reservoir, located in Big Horn, Wyoming, is a Federal-owned structure under the jurisdiction of the Bureau of Land Management. This reservoir serves as a vital debris control system along the Leavitt Draw, with a gravity dam type standing at 27 feet tall and a hydraulic height of 20 feet. With a storage capacity of 54.84 acre-feet and covering a surface area of 13.2 acres, this reservoir plays a crucial role in managing water resources in the region.
Despite its low hazard potential, the reservoir has been assessed as unsatisfactory, highlighting the need for maintenance and potential improvements. The last inspection in August 2016 raised concerns about the condition of the structure, prompting a moderate risk assessment. With a periodic inspection frequency of 5 years, there is a continuous effort to ensure the safety and functionality of Bill Leavitt Reservoir. Climate enthusiasts will be intrigued by the unique design elements of this structure, including its buttress and stone core types, as well as the uncontrolled spillway system in place.
As a key component in the water infrastructure of Greybull, Wyoming, Bill Leavitt Reservoir not only provides vital debris control but also contributes to the overall water management efforts in the region. With its association with the Bureau of Land Management and its strategic location along the Leavitt Draw, this reservoir serves as a testament to the importance of sustainable water resource management in mitigating climate-related risks and ensuring water security for the community.

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 Bill Leavitt Reservoir
Where does the data for Bill Leavitt 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 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.
