Summary
This private-owned dam stands at a height of 25 feet and has a hydraulic height of 24 feet, with a structural height of 26 feet. It has a dam length of 450 feet and a storage capacity of 30 acre-feet, providing valuable water resource management in the area.
With a low hazard potential and a moderate risk assessment, the Charles Mattison Structure Dam plays a crucial role in mitigating flood risks and ensuring water availability for the surrounding area. The dam is primarily made of Earth with a stone core, sitting on a soil foundation. Its uncontrolled spillway and lack of outlet gates indicate a simple yet effective design for grade stabilization purposes. While it has not been rated for condition assessment, the dam continues to operate with no state regulation, inspection, or enforcement, highlighting the importance of private ownership in water resource management.
Situated within the Kansas City District and under the jurisdiction of Missouri, the Charles Mattison Structure Dam stands as a testament to effective water resource management through private ownership. With its strategic location and design, this dam not only stabilizes grades but also contributes to the overall flood control and water storage capacity in the region. Enthusiasts of water resources and climate will appreciate the essential role that this dam plays in ensuring the sustainability and resilience of the local water ecosystem.

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.
