Weaver Dam dam
Weaver Dam
Located in Fergus County, Montana, Weaver Dam stands as a testament to the innovative work of the USDA NRCS in constructing a vital water resource for the surrounding community. Completed in 1966, this earth dam on Dovetail Creek serves multiple purposes, including fire protection, stock watering, and a small fish pond. With a height of 25 feet and a length of 250 feet, Weaver Dam has a storage capacity of 117 acre-feet, offering essential water security in this arid region.
Despite its low hazard potential, Weaver Dam plays a crucial role in mitigating the moderate risk of water scarcity in the area. With a maximum discharge of 600 cubic feet per second and an uncontrolled spillway width of 100 feet, the dam provides a reliable source of water for both human and ecological needs. DNRC oversees the state-regulated dam, ensuring proper inspection, permitting, and enforcement to uphold its structural integrity and safeguard the surrounding environment.
Weaver Dam's strategic location and efficient design highlight the importance of sustainable water management in the face of changing climate conditions. As water resource and climate enthusiasts, we can appreciate the critical role that infrastructure like Weaver Dam plays in supporting local ecosystems and communities, while also adapting to the evolving challenges posed by a shifting climate.
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 Weaver Dam
Where does the data for Weaver Dam 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.
