With a low hazard potential and fair condition assessment, Elrod Lake Dam has a moderate risk level and is inspected every five years to ensure its structural integrity. The dam features an uncontrolled spillway and has a maximum discharge capacity of 404 cubic feet per second. While there are no outlet gates, the dam's foundations consist of soil and core types of stone, providing stability for its operations. The surrounding area offers a serene environment for outdoor activities and wildlife observation, making it a popular destination for both locals and visitors alike.
Elrod Lake Dam's presence on the tranquil waters of Jackson Run in Boone County, Indiana, not only enhances the natural landscape but also provides a safe and enjoyable recreational space for water resource and climate enthusiasts. With its strategic location and well-maintained infrastructure, the dam stands as a testament to the importance of sustainable water management practices while catering to the diverse needs of the community. As a key element in the region's water resource infrastructure, Elrod Lake Dam continues to play a vital role in supporting both environmental conservation and outdoor recreation opportunities.

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.
