Summary

3 Dam, located in Cadet, Missouri, serves as a crucial water resource structure on the Shibboleth Branch. Constructed in 1992, this private-owned Earth dam stands at a height of 74 feet, with a normal storage capacity of 650 acre-feet and a maximum storage of 765 acre-feet. The dam covers a surface area of 27 acres and has a drainage area of 101 square miles, providing essential water management and flood control for the region.

Managed by the DAM AND RESERVOIR SAFETY PROG in Missouri, Cadet No. 3 Dam is regularly inspected and maintained to ensure its structural integrity and safety. With a high hazard potential and a moderate risk assessment rating, the dam has been deemed to be in satisfactory condition as of its last assessment in 2007. Despite its uncontrolled spillway type, the dam has proven to effectively mitigate risks and meet regulatory standards, showcasing its importance in safeguarding the surrounding communities from potential water-related disasters.

As a vital component in the water infrastructure of Washington County, Missouri, Cadet No. 3 Dam plays a significant role in tailings management and water storage. With its strategic location and functional design, this Earth dam stands as a testament to effective water resource management and climate resilience efforts in the region. Its impact on the local ecosystem and community highlights the importance of sustainable water resource development and the critical role of dams in enhancing water security amidst changing climate conditions.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
