About this dam

Deaver

Deaver, located in Park County, Wyoming, is a federal-owned structure managed by the Bureau of Reclamation for the primary purpose of serving as a Fish and Wildlife Pond. Constructed in 1918, this Earth-type dam stands at a height of 16 feet with a length of 1300 feet, providing a storage capacity of 681 acre-feet. Situated on the Shoshone River offstream, Deaver plays a crucial role in irrigation and enhancing the local ecosystem by supporting fish and wildlife habitats.

Despite being categorized as a low hazard potential structure, Deaver is subject to regular state inspections, permitting, and enforcement by the Bureau of Reclamation. The dam's design by JOHN G. LOUTAS ensures its stability and functionality, with one valve outlet gate for water release. Its strategic location and purpose make it a vital component in managing water resources and mitigating potential risks in the region, as highlighted by its high-risk assessment rating of 2.

With a surface area of 80 acres and a drainage area of 1 square mile, Deaver's significance extends beyond mere infrastructure to environmental conservation and water management. As climate change impacts water resources, structures like Deaver play a crucial role in adapting to changing conditions and ensuring sustainable use of water for both human needs and wildlife preservation in the region.

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.

FAQ

About Deaver

Where does the data for Deaver 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.
