Summary

Completed in 1962, this earth dam stands at a height of 35 feet and has a hydraulic height of 30 feet, providing a storage capacity of 77 acre-feet. The dam overlooks an unnamed tributary of the East Branch Sweetwater Creek, creating a surface area of 4 acres and a drainage area of 0.19 square miles.

Despite its low hazard potential, the dam's condition assessment is rated as poor, with the last inspection conducted in September 2016. The risk assessment indicates a high level of risk (2), highlighting the need for improved risk management measures. With no spillway and outlet gates, the dam presents certain challenges in terms of safety and emergency preparedness. Although the dam has not been modified in recent years, its structural integrity and maintenance are vital considerations for ensuring the safety of the surrounding community and environment.

Given its historical significance and recreational value, Seiger Lake Dam underscores the importance of proactive monitoring and maintenance practices. Its location within the Louisville District accentuates the need for continued regulatory oversight and enforcement to mitigate potential risks and safeguard the dam's long-term stability. As water resource and climate enthusiasts, staying informed about the condition and management of dams like Seiger Lake Dam is crucial for promoting sustainable water management practices and protecting our natural resources.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
