Summary
3 is a privately owned earth dam located in Albany, Wyoming, along Goat Creek. Completed in 1970, this dam serves multiple purposes including fire protection, stock watering, and creating a small fish pond. With a dam height of 27 feet and a hydraulic height of 21 feet, it has a normal storage capacity of 23 acre-feet and a maximum storage of 40 acre-feet. The dam has a surface area of 3 acres and a maximum discharge capacity of 600 cubic feet per second.
Despite its low hazard potential, Patrick Ryan No. 3 is currently in poor condition, as indicated by a 2019 inspection report. The dam's spillway is uncontrolled and has a width of 50 feet. While the dam has one uncontrolled outlet gate, it lacks proper maintenance and emergency action preparedness, which raises concerns regarding its safety during flooding events. The risk assessment for the dam is moderate, and it is important for the owner to address the poor condition and implement necessary risk management measures to ensure the safety of the structure and downstream areas.
Given its location in a remote area and the potential impact on the surrounding environment, it is crucial for the owner of Patrick Ryan No. 3 to prioritize maintenance and rehabilitation efforts. With proper upkeep and adherence to regulatory requirements, this dam can continue to serve its intended purposes effectively while minimizing the risk of failure and ensuring the safety of the community and ecosystem downstream of Goat Creek.

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.
