Bruce No. F.S. 9-313-1 dam
Bruce No. F.S. 9-313-1
Bruce No. F.S. 9-313-1 is a Federal-owned Earth dam located in Weston, Wyoming, along the Williamson Draw river. Built in 1969, this dam serves multiple purposes, including fire protection, stock watering, and creating a small fish pond. With a height of 22 feet and a storage capacity of 73 acre-feet, it covers a surface area of 7 acres and drains a 1.4 square mile watershed. The dam has a low hazard potential and is in fair condition, as assessed during the last inspection in July 2020.
Despite its modest size and capacity, Bruce No. F.S. 9-313-1 plays a crucial role in water resource management and wildlife habitat in the region. The dam provides a reliable source of water for firefighting, livestock, and small fish populations, contributing to the overall ecosystem health. Its location on HWY 450 near the Omaha District makes it easily accessible for maintenance and monitoring, ensuring its continued functionality and safety for the surrounding community.
While the dam has seen no major modifications since its construction, it is subject to regular inspections and enforcement by the Wyoming State Regulatory Agency to ensure compliance with safety standards. With a moderate risk rating and an established emergency action plan, Bruce No. F.S. 9-313-1 remains a vital infrastructure for water conservation and climate resilience efforts in the area. Its presence highlights the importance of sustainable water management practices in mitigating the impacts of climate change on local ecosystems and communities.

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 Bruce No. F.S. 9-313-1
Where does the data for Bruce No. F.S. 9-313-1 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.
