Summary
Built in 1972 for recreational purposes, this 12-foot tall structure has a storage capacity of 96 acre-feet and a surface area of 15 acres. With a low hazard potential and a condition assessment that is currently not rated, Mononame 47 serves as a picturesque spot for water resource and climate enthusiasts to explore.
Managed by the Kansas City District of the US Army Corps of Engineers, Mononame 47 has not been modified over the years and does not have a designated spillway. Despite its low hazard potential, the dam's emergency action plan and risk assessment measures are currently not assessed or updated. With its serene surroundings and the beauty of the TR Osage River, Mononame 47 offers a tranquil setting for outdoor recreation and wildlife observation, making it a must-visit destination for nature lovers and water resource enthusiasts in Missouri.
As an unregulated and uninspected dam, Mononame 47 presents a unique opportunity for visitors to appreciate the natural beauty of Vernon County while also recognizing the importance of proper dam maintenance and emergency preparedness.

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.
