Summary
3, located in Green River, Wyoming, serves as a vital debris control structure along Allied Draw and Tr Blacks Fork Ri. Constructed in 1981, this private earth dam stands at a height of 37 feet with a storage capacity of 2975 acre-feet. The dam's primary purpose is debris control, safeguarding the surrounding area from potential hazards.
With a fair condition assessment and low hazard potential, Pond No. 3 is well-maintained and poses minimal risk to the community. The structure, designed by David Scriven of Western States Mining Consultants, has a hydraulic height of 32 feet and a structural height of 37 feet. Despite its age, the dam continues to effectively fulfill its intended function.
Although the pond does not feature a spillway, it has a surface area of 280 acres and serves as a critical resource in managing water flow in the region. With regular inspections and enforcement of state regulations, Pond No. 3 remains a reliable asset in the water resource infrastructure of Sweetwater County, Wyoming.

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.
