Summary
Built in 1940, this earth dam reaches a height of 25 feet and spans 615 feet in length, creating a reservoir with a storage capacity of 91 acre-feet. Despite its impressive size, the dam is classified as having a significant hazard potential and poor condition assessment, making it a site of moderate risk.
The dam features an uncontrolled spillway and no outlet gates, posing challenges for managing water levels and discharge. The last inspection in July 2018 revealed the dam's structural integrity to be in need of improvement, with a recommended inspection frequency of every three years. While the dam is state-regulated and subject to permitting, inspection, and enforcement by the Indiana Department of Natural Resources, its ownership, primary purpose, and associated structures remain undisclosed.
Water resource and climate enthusiasts may be intrigued by the ecological implications of the Loew Lake Dam (South) and the potential risks it poses to surrounding communities. With its historical significance and current state of disrepair, this dam serves as a reminder of the importance of proactive maintenance and monitoring to ensure the safety and sustainability of our water infrastructure in the face 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.
