Summary

16, located in Millport, Indiana, is a crucial infrastructure for flood risk reduction along an unnamed tributary of Delaney Creek. Constructed in 1982 by the USDA NRCS, this earth dam stands at a height of 35.2 feet and has a storage capacity of 167 acre-feet. Despite its importance in mitigating flood hazards, the dam is classified with a high hazard potential and poor condition assessment.

With a drainage area of 0.45 square miles, Delaney Creek Dam No. 16 plays a vital role in protecting the surrounding community from potential flooding events. However, the dam's poor condition raises concerns about its ability to withstand future challenges. The dam lacks outlet gates and has an uncontrolled spillway, indicating potential vulnerabilities that may need to be addressed to ensure its effectiveness in flood risk reduction efforts.

In light of the dam's moderate risk assessment and the need for improvement in its condition, ongoing inspections and maintenance are essential to safeguard the local area from potential flooding disasters. As water resource and climate enthusiasts, monitoring the state of Delaney Creek Dam No. 16 and advocating for necessary upgrades can help enhance its resilience and ensure continued protection for the community it serves.

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.
