Arens Lake Dam Reservoir Report
Nearby: Leona Lake Dam Upper Spring Lake Dam
Last Updated: March 16, 2026
Arens Lake Dam, located in Morgan County, Indiana, was completed in 1978 for the primary purpose of recreation.
Summary
This private earth dam stands at a height of 16 feet and has a hydraulic height of 18 feet, with a length of 190 feet. The dam has a storage capacity of 92 acre-feet and a normal storage of 30 acre-feet, covering a surface area of 5.93 acres.
With a significant hazard potential, the condition of Arens Lake Dam has not been rated since its last inspection in 1996. While it is not state-regulated or permitted, the dam poses potential risks that draw attention to the importance of monitoring and maintaining its structural integrity. The dam's location in a scenic area with a drainage area of 0.46 square miles highlights the balance between its recreational benefits and the need for careful oversight to ensure public safety and environmental preservation in light of changing climate conditions.

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.
