Summary
Marys, Missouri, was completed in 1969 with the primary purpose of flood risk reduction. Standing at a height of 27 feet and with a storage capacity of 87 acre-feet, this earth dam on TR Pickle Creek serves as a critical infrastructure in the region. Despite being privately owned, the dam is not regulated by the state and has not been inspected or rated for its condition.
The dam's hazard potential is classified as high, highlighting the importance of regular maintenance and monitoring. With a normal storage capacity of 38 acre-feet and serving as a recreational area as well, the dam plays a vital role in both flood control and community enjoyment. However, the lack of regulatory oversight raises concerns about its long-term safety and resilience in the face of changing climate patterns.
As water resource and climate enthusiasts, it is crucial to recognize the significance of dams like Spring Hart Lake Dam in managing flood risks and providing recreational opportunities. Advocating for regular inspections, maintenance, and potential enhancements to its infrastructure can ensure the safety and longevity of such vital water management structures in the face of increasing climate variability.

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.
