Summary
The dam, primarily designed for flood control and water supply purposes, stands as a crucial structure in the region's water resource management system. With a high hazard potential but a satisfactory condition assessment, the dam is regulated, inspected, and enforced by the DAM AND RESERVOIR SAFETY PROG of the state.
Situated in the St. Louis District and under the jurisdiction of Missouri, Dudenhoeffer Dam plays a vital role in regulating the flow of water and ensuring the safety of nearby communities. With a drainage area of 376 square miles and a maximum discharge capacity of 892 cubic feet per second, the dam provides crucial protection against flooding events and helps in maintaining a stable water supply for the region. Despite its high hazard potential, Dudenhoeffer Dam remains a reliable structure with a satisfactory condition assessment, as of the last inspection in December 2017.
Managed by private owners, Dudenhoeffer Dam showcases the importance of effective dam safety regulations and routine inspections to ensure the structural integrity and functionality of such critical infrastructure. With its significant storage capacity, hydraulic height, and strategic location in Maries County, this dam stands as a testament to the collaborative efforts of state agencies, private owners, and regulatory bodies in safeguarding water resources and mitigating climate-related risks 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.
