Summary

Built in 2000 by the USDA NRCS, this dam stands at a height of 29 feet with a hydraulic height of 28 feet and a structural height of 34 feet. It spans 310 feet in length and has a storage capacity of 34 acre-feet, serving a drainage area of 95 acres.

Despite being uncontrolled, the dam boasts a low hazard potential and a moderate risk assessment rating. With a maximum discharge capacity of 60 cubic feet per second and a spillway width of 20 feet, it offers a crucial water resource for the surrounding area. The dam's inspection frequency is rated at 0, with a condition assessment of "Not Rated," highlighting the need for ongoing maintenance and monitoring to ensure its structural integrity and safety.

Overall, the Paul Isaacson Dam plays a vital role in providing essential water resources for fire protection and livestock in College Mound, Missouri. As a key structure along the TR-Middle Fork Chariton River, it serves as a testament to the importance of sustainable water management practices in mitigating climate-related risks and supporting local ecosystems. Through continued oversight and risk management measures, this dam will continue to safeguard the community and enhance resilience to changing environmental 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.
