Summary
2 is a privately owned earth dam located in St. Peters, Missouri, along the tributary of Dardenne Creek. Built in 1965 for recreational purposes, this dam stands at a height of 32 feet and has a storage capacity of 68 acre-feet. Despite not being regulated by the state, this dam has a high hazard potential and has not been rated for its current condition.
The dam's primary purpose is for recreation, with a surface area of 4 acres and a drainage area of 95 square miles. While it does not have a spillway or outlet gates, it is designed as a buttress dam. The last inspection of this dam was conducted in 1980, and its emergency action plan status and risk assessment are unknown.
Located in a picturesque setting, Park Charles South No. 2 offers a tranquil spot for outdoor enthusiasts to enjoy nature and water-based activities. Its historical significance as a recreational structure adds to its appeal for water resource and climate enthusiasts seeking to explore the intersection of human-made infrastructure and natural ecosystems.

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.
