Summary
Constructed in 1994, this earth dam stands at a height of 29.6 feet and has a hydraulic height of 28 feet. With a normal storage capacity of 12 acre-feet and a maximum storage of 35 acre-feet, Eason Dam covers a surface area of 6.1 acres and serves a drainage area of 90.88 square miles.
Despite being privately owned and not regulated by the state, Eason Dam plays a crucial role in managing water resources in the region. With a low hazard potential and a moderate risk assessment rating, the dam has not been inspected or assessed for its condition recently. The dam features an uncontrolled spillway type and does not have any outlet gates.
For water resource and climate enthusiasts, Eason Dam provides an intriguing case study in private dam ownership and management. Its role in grade stabilization along the TR-Chariton River, its modest height and storage capacity, and its unregulated status offer valuable insights into the diverse landscape of dam infrastructure in the United States. The dam's history, design, and risk assessment present a compelling narrative for those interested in the intersection of water resources, infrastructure management, and environmental risk assessment.

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.
