Summary
1 Dam 1a (2nd Enl.) is a privately owned earth dam located in Park, Wyoming, along the Sage Creek. Built in 1953 by designer Howard F. Bell, this dam primarily serves the purpose of irrigation, with a storage capacity of 783 acre-feet. Standing at a height of 24 feet, the dam spans 465 feet in length, providing essential water resources for the surrounding area.
Despite being classified as having a low hazard potential, the dam is regularly inspected and maintained, with the last assessment conducted in August 2019 showing a fair condition. The dam features an uncontrolled spillway with a width of 20 feet and a single valve outlet gate. While the risk assessment is moderate, with a rating of 3, the dam has not had any significant modifications or emergency preparedness measures in place, indicating a need for continued monitoring and potential updates to ensure its safety and efficacy in the face of changing climate conditions.
Situated in a picturesque location and playing a crucial role in supporting local agriculture through irrigation, Foster No. 1 Dam 1a (2nd Enl.) stands as a testament to the importance of sustainable water resource management in the region. With its historical significance and ongoing commitment to regulatory compliance and maintenance, this dam serves as a vital infrastructure asset for the community, highlighting the intersection of water resource management and climate resilience in 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.
