Summary
Completed in 2000, this irrigation dam stands at a height of 18 feet and has a storage capacity of 150 acre-feet, serving multiple purposes including fish and wildlife pond, flood risk reduction, and irrigation. The dam has a spillway width of 16 feet and is equipped with other controlled outlet gates, with a low hazard potential and a satisfactory condition assessment.
Situated in Congressional District 00, Wyoming, Snyder plays a crucial role in managing water resources in the area, with a drainage area of 3.4 square miles and a maximum discharge of 78 cubic feet per second. Despite being a moderate risk structure, Snyder has not undergone any modifications since its completion and is subject to regular inspections to ensure its continued safety and functionality. With Liz Cheney (R) as the representative for the district, Snyder remains an important asset for water supply and management in the region.
Overall, Snyder stands as a testament to effective water resource management, providing essential services such as irrigation and flood risk reduction. With a low hazard potential and satisfactory condition assessment, this privately owned dam continues to contribute to the sustainable use of water resources in Park, Wyoming, highlighting the importance of maintaining and monitoring infrastructure for climate resilience and water security in the region.

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.
