Summary
Built in 1969, this earth dam stands at a height of 33 feet and has a storage capacity of 194 acre-feet. With a primary purpose of recreation, the dam offers opportunities for fishing, boating, and other water-based activities on its 11-acre surface area.
Despite its recreational appeal, Dirkemeier Lake Dam- Mononame 314 is classified as having a high hazard potential. However, its current condition has not been rated, and the last inspection was conducted in 1979. The dam's emergency action plan status and risk management measures are unknown, raising concerns about its safety and preparedness in the event of an emergency. The dam is not under state regulation or jurisdiction, and it lacks regular inspections and enforcement measures.
Located on TR-LOST CREEK in Warren County, Dirkemeier Lake Dam- Mononame 314 is a notable structure within the St. Louis District of Missouri. With its picturesque setting and recreational opportunities, the dam serves as a popular destination for water resource and climate enthusiasts. However, given its high hazard potential and lack of recent assessment and emergency preparedness, there are important considerations for ensuring the safety and sustainability of this recreational facility in the future.

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.
