Summary
Built in 1974, this earth dam stands at a height of 43 feet and stretches 520 feet in length, creating a reservoir with a maximum storage capacity of 750 acre-feet. The primary purpose of this dam is for recreation, providing a surface area of 21.7 acres for water enthusiasts to enjoy various activities.
The dam is regulated by the Indiana Department of Natural Resources and undergoes regular inspections, with the most recent assessment in August 2020 rating its condition as fair. Despite being classified as having a high hazard potential, the risk assessment is moderate, indicating that risk management measures are in place. With its uncontrolled spillway and proximity to the Flatrock River tributary, Closser Lake Dam serves as both a recreational destination and a critical infrastructure for water resource management in the region.
Overall, Closser Lake Dam represents a significant engineering feat in balancing the needs of recreation and water management. Its location within the Louisville District and oversight by the state regulatory agency underscores the importance of this dam in maintaining water quality, flood control, and public safety in the surrounding area. For water resource and climate enthusiasts, Closser Lake Dam is a key landmark to study and appreciate the intersection of human development and environmental stewardship.

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.
