Summary
The dam stands at a height of 34 feet with a hydraulic height of 26 feet and a structural height of 33 feet. With a storage capacity of 69 acre-feet, Dana Meadows spans 550 feet in length and covers a surface area of 4 acres. The dam is regulated by the state and undergoes regular inspections, with the last assessment conducted in May 2021 revealing a poor condition.
Despite its low hazard potential, Dana Meadows is considered to have a moderate risk level, indicating the need for ongoing monitoring and risk management measures. The dam features an uncontrolled spillway type with a width of 100 feet and an outlet gate for controlled water release. Situated along Hanna Creek, the dam serves as a vital resource for the local community in Alcova, providing critical water storage for firefighting purposes and livestock use. For water resource and climate enthusiasts, Dana Meadows presents an intriguing case study in dam infrastructure and management within the Wyoming landscape.

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.
