Summary
This privately-owned earth dam stands at a height of 25 feet and has a storage capacity of 67 acre-feet. Situated on the TR-West Locust Creek, the dam serves as a popular spot for outdoor enthusiasts to enjoy the surrounding natural beauty.
With a low hazard potential and a condition assessment of "Not Rated," Seaton Lake Dam is a reliable structure that contributes to the local water resource management. Despite not being regulated or inspected by the state, the dam continues to provide recreational opportunities for visitors, with a surface area of 5 acres and a drainage area of 36 square miles. The dam's primary purpose is for recreation, making it a key feature in the landscape of Putnam County, Missouri.
Although Seaton Lake Dam may not have a designated spillway or outlet gates, its historical significance as a recreational site and its low risk assessment make it a valuable asset to the community. As water resource and climate enthusiasts visit this dam, they can appreciate its role in providing a serene and scenic environment for outdoor activities in the heart of Missouri's countryside.

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.
