Summary

This private Earth dam stands at a height of 21 feet and has a length of 256 feet, providing a storage capacity of 64 acre-feet. With a normal storage capacity of 9 acre-feet and a surface area of 5.24 acres, the dam plays a crucial role in managing water levels and supporting various recreational activities in the area.

Despite its significant contributions to the local community, Schacht Lake Dam is classified as having a high hazard potential, although its condition assessment remains unrated. The last inspection was conducted in March 2002, highlighting the need for continued monitoring and maintenance to ensure the dam's structural integrity and safety. While the dam is not regulated by the state, its importance in water resource management and recreation underscores the importance of implementing appropriate risk management measures to mitigate potential hazards and ensure the safety of surrounding areas.

For water resource and climate enthusiasts, Schacht Lake Dam offers a fascinating case study in the intersection of human intervention and natural ecosystems. As a key piece of infrastructure in Indiana, the dam provides valuable insights into the challenges and opportunities associated with managing water resources for both recreational and conservation purposes. By understanding the complexities of maintaining a dam like Schacht Lake, enthusiasts can gain a deeper appreciation for the delicate balance between human needs and environmental sustainability in the face of changing climate patterns.

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.
