Summary
Owned and regulated by a private entity, the dam is designed by the USDA NRCS and is under the jurisdiction of the Iowa Department of Natural Resources. With a height of 37 feet and a length of 256 feet, the dam has a storage capacity of 46 acre-feet and serves the North Raccoon River.
Despite being classified as having a low hazard potential and a moderate risk level, Eason Dam has not been rated for its condition assessment. The dam features an uncontrolled spillway type with no outlet gates or locks. With a drainage area of 0.3 square miles and a surface area of 3 acres, the dam plays a crucial role in managing water resources in the area. Although it has not been recently inspected or assessed for its emergency action plan, Eason Dam remains an important structure for the surrounding community.
As a vital component of the local water infrastructure, Eason Dam contributes to the overall water management and conservation efforts in the region. Its modest size and purpose make it a key asset for fire protection and agricultural needs. With a focus on safety and risk management, ongoing assessments and inspections will be important to ensure the continued reliability and effectiveness of Eason Dam for years to come.

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.
