Summary
The dam, with a height of 26 feet and a length of 625 feet, serves primarily for recreational purposes. However, the dam's condition assessment is deemed poor, with a significant hazard potential and a high risk rating. The last inspection in 2018 revealed the need for maintenance and improvement measures to ensure the dam's safety and functionality.
Despite being regulated by the Indiana Department of Natural Resources and regularly inspected, Wildwood Lake Dam poses a risk due to its current condition. The dam lacks a spillway, outlet gates, and emergency action plan, raising concerns about its ability to handle potential flooding events. With a normal storage capacity of 100 acre-feet and a surface area of 15 acres, the dam's inadequate maintenance and risk management measures highlight the importance of addressing safety concerns to protect surrounding communities and downstream areas from potential hazards.
Wildwood Lake Dam's location in a high-risk category and its poor condition assessment underscore the need for immediate attention and potential rehabilitation efforts. With a significant hazard potential and the absence of critical safety features, such as a spillway and emergency action plan, the dam's risk to surrounding areas cannot be overlooked. Climate and water resource enthusiasts should advocate for improved infrastructure and risk management measures to safeguard communities and the environment from the potential consequences of a dam failure at Wildwood Lake.

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.
