Summary

1, also known as Seldom Seen Lake, is a crucial water resource structure located in Kossuth, Indiana. Owned by the local government and regulated by the Indiana Department of Natural Resources, this earth dam was completed in 1971 for the primary purpose of flood risk reduction along the unnamed tributary of Delaney Creek. With a structural height of 59 feet and a storage capacity of 1390 acre-feet, this dam plays a vital role in managing water flow and mitigating potential flooding in the area.

Despite its importance, Delaney Creek Dam No. 1 is currently facing challenges, as indicated by a poor condition assessment in 2009 and a high hazard potential. The last inspection in 2018 highlighted the need for improvements and maintenance to ensure its effectiveness in safeguarding the surrounding communities. With a moderate risk assessment rating, there is a pressing need for risk management measures to be implemented to enhance the dam's resilience and reduce the potential impact of any emergencies that may arise.

Efforts to address the deficiencies of Delaney Creek Dam No. 1 are essential to protect the local area from the threat of flooding and ensure the long-term sustainability of this critical water resource infrastructure. Collaboration between relevant agencies, stakeholders, and the community will be vital in implementing necessary upgrades and maintenance to improve the dam's condition and enhance its overall performance in managing water resources and climate challenges.

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.
