Weaver dam
Weaver
Weaver, located in Albany County, Wyoming, is a private dam with a primary purpose of fire protection, stock, or small fish pond. Completed in 1972, this earth dam stands at 29 feet high and spans 495 feet in length, with a maximum storage capacity of 145 acre-feet and a normal storage of 100 acre-feet. The dam serves the functions of irrigation, in addition to its primary purposes, and is situated on Harney Creek, a tributary of the Laramie River.
Despite its low hazard potential, Weaver's condition assessment is rated as poor, indicating a need for maintenance and repairs. The dam is inspected every 5 years, with the most recent assessment conducted in July 2021. The spillway type is uncontrolled, with a width of 20 feet, and the outlet gates consist of a single slide (sluice gate). While the risk assessment is moderate, with a score of 3, there are currently no specific risk management measures or emergency action plans in place for Weaver.
For water resource and climate enthusiasts, Weaver presents an intriguing case study of a privately owned dam in Wyoming that serves multiple water management purposes. With its unique design features and operational characteristics, Weaver demonstrates the importance of regular inspections and maintenance to ensure the safety and effectiveness of water infrastructure in the face of changing climate conditions. As efforts continue to address the poor condition assessment and moderate risk level of Weaver, there is a valuable opportunity for stakeholders to collaborate on enhancing the resilience of this essential water resource facility.
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
Where does the data for Weaver 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.
