Summary
The dam stands at a height of 28 feet and has a length of 350 feet, with a storage capacity of 76 acre-feet. It serves various purposes including fire protection, stock, and small fish pond management, making it an essential resource for the local community.
The dam is regulated and inspected by the Illinois Department of Natural Resources, ensuring its safety and compliance with state regulations. With a low hazard potential and a moderate risk assessment rating, Eaton Lake Dam 1 is considered to be a vital infrastructure with well-maintained conditions. The surrounding area, including the Embarrass River, benefits from the dam's water storage and flood control capabilities.
As a part of the St. Louis District, Eaton Lake Dam 1 plays a crucial role in water resource management in Jasper County, Illinois. With its uncontrolled spillway and outlet gates, the dam provides necessary water management functions while minimizing risks to the surrounding environment. Climate and water resource enthusiasts can appreciate the engineering and regulatory efforts that go into maintaining this important structure for the benefit of the community and the 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.
