Summary
Completed in 1968, this private-owned earth dam stands at a height of 22 feet and has a storage capacity of 211 acre-feet. Its primary purpose includes flood risk reduction, while also supporting fish and wildlife habitats, irrigation, and water supply management in the region.
With a low hazard potential and a moderate risk assessment rating, Elliot Lake Dam is a key component of the local water resource infrastructure. The dam's uncontrolled spillway, with a width of 300 feet, helps manage maximum discharge levels of up to 850 cubic feet per second. While the dam is not regulated by the state and does not have a formal inspection schedule, its role in mitigating flood risks and supporting water resource management in the area is essential for the community's resilience to changing climate conditions.
As water resource and climate enthusiasts, understanding the importance of structures like Elliot Lake Dam in safeguarding communities against flood risks and supporting sustainable water management practices is crucial. With its strategic location along the TR-Spring River and its versatile purposes, this earth dam stands as a testament to the intricate balance between human infrastructure and natural ecosystems in the face of evolving climate challenges.

Dam Data Reference
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.
