Summary
With a height of 32 feet and a length of 378 feet, this dam has a storage capacity of 109 acre-feet and a surface area of 4 acres. Despite being classified as low hazard potential, the dam is considered to have a moderate risk assessment rating.
The dam features an uncontrolled spillway with a width of 15 feet and has no outlet gates or associated structures. While it has not been rated for its condition assessment, the dam is currently in operation without any state regulation or inspection requirements. The surrounding area is under the jurisdiction of the Kansas City District, and the dam is located within the congressional district represented by Blaine Luetkemeyer.
Water resource and climate enthusiasts may find Schupmann Lake Dam to be an interesting structure due to its unique design and purpose. Its location along TR-COON CREEK and the surrounding landscape of Chain of Rocks in Missouri offer a picturesque setting for those interested in studying dam infrastructure and its impact on the local environment. Despite its low hazard potential, the moderate risk assessment rating highlights the importance of ongoing monitoring and maintenance to ensure the dam's continued safety and functionality.

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.
