Summary
The earth dam, standing at a height of 32 feet, boasts a storage capacity of 274 acre-feet and covers a surface area of 16 acres. With a drainage area of 310 square miles and a hazard potential rated as high, this dam plays a crucial role in managing water resources in the region.
Situated along a tributary to Tuque Creek, Schmitt Lake Dam serves as a key component in the St. Louis District's water management system. Despite not being regulated by the state or federal agencies, the dam's condition is currently not rated, highlighting the importance of regular inspections and maintenance to ensure its structural integrity and prevent potential hazards. Enthusiasts of water resources and climate will find Schmitt Lake Dam to be a fascinating case study of a privately owned infrastructure contributing to both recreation and water management in Warren County, Missouri.
As climate change continues to impact water resources, structures like Schmitt Lake Dam will play an increasingly vital role in mitigating flood risks and ensuring sustainable water supply for the surrounding communities. With its high hazard potential and unregulated status, the dam presents a unique opportunity for stakeholders to collaborate on risk assessment, emergency preparedness, and long-term management strategies. By understanding and addressing the challenges faced by dams like Schmitt Lake, enthusiasts can contribute to the resilience and sustainability of water resources in the face of a changing climate.

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.
