Summary
Built in 1941, this gravity dam on Silver Creek serves multiple purposes including fire protection, stock watering, and as a small fish pond. With a normal storage capacity of 104 acre-feet and a maximum storage of 145 acre-feet, the reservoir covers an area of 11.24 acres and has a hydraulic height of 20 feet.
The dam structure, primarily made of stone and buttress, stands at a height of 25 feet and is 334 feet long. While the reservoir has a low hazard potential, its condition assessment is rated as fair. The dam features an uncontrolled spillway with a width of 2 feet and does not have outlet gates. The last inspection was conducted in November 2018, with a scheduled frequency of 5 years. Despite its moderate risk assessment, Silver Creek Reservoir remains a vital resource for water management and conservation in Fremont County, Wyoming.
As an important component of the local water infrastructure, Silver Creek Reservoir plays a crucial role in ensuring water availability for firefighting, livestock, and recreational activities. The dam is regulated by the State of Wyoming and inspected regularly to maintain its structural integrity and operational efficiency. With its scenic location along Silver Creek and the Sacramento District, the reservoir represents a harmonious blend of natural beauty and human intervention, serving as a testament to responsible water resource management in the region.

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.
