Summary

The dam, standing at a height of 31 feet with a length of 205 feet, creates a reservoir with a storage capacity of 34 acre-feet and a surface area of 1.97 acres. The dam is located on an unnamed tributary of Mud Creek and is regulated by the Indiana Department of Natural Resources.

Despite its recreational value, Roger Young Lake Dam poses a significant hazard potential with a poor condition assessment, indicating a need for maintenance and risk management measures. The dam lacks a spillway and outlet gates, further adding to the risk associated with potential overflow events. The last inspection in August 2019 revealed the dam's deteriorating state, emphasizing the importance of timely assessments and interventions to ensure public safety and environmental protection.

Given the high risk and poor condition of Roger Young Lake Dam, it is crucial for the private owners and regulatory agencies to prioritize maintenance and risk mitigation efforts. With its location in a densely populated area, any failure or breach of the dam could have severe consequences. Regular inspections, emergency action plans, and necessary repairs are essential to safeguard the surrounding community and preserve the ecological balance of the water resources in the region.

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.
