Summary

Completed in 1940, this privately owned Earth dam spans 360 feet in length and reaches a height of 22 feet, creating a reservoir with a storage capacity of 232 acre-feet. Situated along an unnamed tributary of Big Lick Creek, the dam offers a surface area of 24.2 acres for outdoor enthusiasts to enjoy activities like fishing, boating, and picnicking.

Despite its historical significance and recreational value, Lake Mohee Dam has faced challenges in terms of its condition assessment, which was deemed poor during the last inspection in 2000. The dam's hazard potential is categorized as low, yet the risk assessment indicates a high level of risk. With a history of state regulation, inspection, and enforcement, the dam continues to be monitored closely by the Indiana Department of Natural Resources to ensure public safety and the preservation of its ecological surroundings.

As climate change poses a growing threat to water resources, Lake Mohee Dam serves as a critical infrastructure for both flood control and water storage in the region. With its unique blend of historical charm and recreational opportunities, the dam remains a focal point for water resource and climate enthusiasts seeking to understand the delicate balance between human intervention and natural ecosystems in the face of a changing climate.

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.
