Summary
Built in 1954, this rockfill dam stands at a height of 20 feet and has a storage capacity of 54 acre-feet. With a surface area of 5 acres and a drainage area of 80 acres, the dam serves as a crucial water resource for the surrounding area.
Despite being privately owned, Mononame 658 falls under the jurisdiction of the state of Missouri and is not regulated or inspected by state agencies. With a low hazard potential and a condition assessment that is currently not rated, this dam plays a vital role in water management and conservation efforts in the region. Furthermore, its location near TR CYNTHIA CR highlights the importance of dams in ensuring water security and supporting various recreational activities.
As a structure with historical significance dating back to the mid-20th century, Mononame 658 serves as a reminder of the importance of sustainable water resource management in the face of changing climatic conditions. With its multiple purposes and low hazard potential, this dam stands as a testament to the intersection of human ingenuity and environmental stewardship in the realm of water infrastructure.

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.
