Summary
Completed in 1952, this earth dam spans 660 feet in length and reaches a height of 51 feet, with a storage capacity of 45,700 acre-feet. Situated on Beanblossom Creek, the dam's spillway, measuring 329 feet wide, helps manage a maximum discharge of 33,500 cubic feet per second.
Maintained by local government authorities and regulated by the Indiana Department of Natural Resources, Lake Lemon Dam boasts a satisfactory condition assessment with a high hazard potential. Despite its age, the dam remains structurally sound and meets safety guidelines. The surrounding area covers 70.9 square miles, offering a surface area of 1,650 acres for recreational activities, making it a popular destination for water resource and climate enthusiasts.
With a moderate risk assessment rating of 3, Lake Lemon Dam continues to play a crucial role in water management for the region. Its strategic location and efficient design by HARZA Engineering ensure the safety of nearby communities and the preservation of the water supply. As a focal point for both local residents and visitors, the dam serves as a testament to effective infrastructure planning and management 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.
