Summary
This earth dam stands at a height of 27 feet, with a hydraulic height of 25 feet and a structural height of 32 feet. The dam stretches 340 feet in length and has a maximum storage capacity of 29.7 acre-feet, serving a drainage area of 100 acres. The dam's spillway is uncontrolled with a width of 10 feet, and it has a low hazard potential with a moderate risk assessment rating.
Despite being privately owned, Wendt Dam plays a crucial role in managing water resources in the region, particularly for grade stabilization. Its earth structure, supported by stone core and soil foundation, ensures the safety and stability of the dam. With a surface area of 15 acres and a normal storage capacity of 22.1 acre-feet, the dam provides essential flood control measures and supports the surrounding ecosystem along the TR-South Wyaconda river.
Maintaining a low hazard potential and a moderate risk assessment rating, Wendt Dam stands as a testament to effective water resource management and climate adaptation efforts in Scotland County, Missouri. With its construction overseen by the Natural Resources Conservation Service, the dam continues to serve its primary purpose while contributing to the resilience of the local community and environment in the face of changing climatic conditions.

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.
