Summary
Kopp Dam #2, located in Knox, Indiana, is a privately owned earth dam completed in 1978 primarily for recreational purposes. Standing at 22 feet in height with a hydraulic height of 28 feet, this dam controls an unnamed tributary of the Wabash River and has a maximum storage capacity of 76 acre-feet. Despite its limited surface area of 3 acres and drainage area of 0.21 square miles, the dam plays a significant role in managing water resources and providing recreational opportunities in the region.
With a poor condition assessment and a significant hazard potential, Clarence H. Kopp Dam #2 requires regular inspections and maintenance to ensure its structural integrity and the safety of surrounding communities. The dam's high risk assessment rating underscores the importance of proactive risk management measures and emergency preparedness. The absence of a spillway and outlet gates adds another layer of complexity to the dam's operation and maintenance, making it crucial for the private owner to work closely with regulatory agencies like the Indiana Department of Natural Resources to address any safety concerns and mitigate risks effectively.
As a key feature in the local water infrastructure, Clarence H. Kopp Dam #2 serves as a vital resource for both water management and recreational activities. Its strategic location and functional design make it a valuable asset for the community, underscoring the importance of ongoing monitoring and maintenance to ensure its long-term viability and safety in the face of changing climate conditions and increasing water-related challenges.

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.
