Summary
1 is a private-owned structure located in Green River, Wyoming, with a low hazard potential. The dam is primarily used for tailings disposal and stands at a height of 38 feet with a length of 1100 feet. Although it is not regulated by the state, it falls under the jurisdiction of the Mine Safety and Health Administration for inspections and enforcement. The pond has a storage capacity of 600 acre-feet and is not currently in use for any other purposes.
Despite its non-regulated status, Tailings Pond No. 1 poses a low risk due to its condition assessment being currently unavailable. The emergency action plan (EAP) status and risk assessment for the pond are also not provided in the data. Its location in Sweetwater County, Wyoming, and proximity to the Sacramento District of the US Army Corps of Engineers make it an important structure for water resource and climate enthusiasts to monitor for potential environmental impacts. While it may not currently have a significant impact on its surroundings, regular monitoring and maintenance of Tailings Pond No. 1 will be essential to ensure its safe operation and prevent any potential hazards in the future.

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.
