Summary
Completed in 2013, this dam serves primarily for irrigation purposes and has a maximum storage capacity of 46 acre-feet. With a structural height of 29 feet and a spillway width of 6 feet, the dam is classified as having a low hazard potential and fair condition assessment.
The dam features a single valve outlet gate and is inspected every 5 years, with the last inspection conducted in May 2019. Despite its moderate risk assessment rating, there are no emergency action plans or inundation maps prepared for the dam. Owned and regulated by the state of Wyoming, Dunning Senw S 32 demonstrates the importance of maintaining and monitoring water infrastructure to ensure the safety and sustainability of water resources in the region.
As a vital component of the local water management system, Dunning Senw S 32 plays a crucial role in providing water for irrigation, fire protection, stock, and small fish ponds in the area. With its strategic location and purpose, this dam serves as a key resource for the community and highlights the significance of proactive risk management and maintenance practices in safeguarding water resources and mitigating potential hazards associated with dams.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
