Summary
2 Dam, is a privately owned structure located in Washington, Missouri. Completed in 1963, this dam serves the primary purpose of tailings containment and stands at an impressive height of 89 feet with a structural height of 95 feet. With a storage capacity of 1191 acre-feet and a drainage area of 46 square miles, this dam plays a crucial role in managing water resources in the region.
Despite its age, Mineral Point #2 has been deemed to be in satisfactory condition with a high hazard potential. The dam is regulated and inspected by the DAM AND RESERVOIR SAFETY PROG in Missouri, ensuring that it meets safety standards. The spillway, with a width of 66 feet, is uncontrolled, and the dam has a maximum discharge capacity of 215 cubic feet per second. Overall, Mineral Point #2 serves as a vital infrastructure for water resource management in the area.
With a moderate risk assessment rating of 3, Mineral Point #2 is an essential component of the local water resource infrastructure. The dam's satisfactory condition and regulated inspection ensure that it continues to effectively serve its purpose of tailings containment and water management. As climate change impacts water resources, structures like Mineral Point #2 play a critical role in ensuring the safety and sustainability of water supplies for communities 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.
