Summary

12, located in Millport, Indiana, is a crucial structure designed for flood risk reduction along an unnamed tributary of Delaney Creek. Built in 1982 by the USDA NRCS, this earth dam stands at a height of 38 feet and stretches 314 feet in length. With a storage capacity of 147 acre-feet, this dam serves to protect the surrounding area from potential flooding, especially during periods of high discharge reaching up to 2400 cubic feet per second.

Despite being classified as having a high hazard potential, Delaney Creek Dam No. 12 is assessed to be in fair condition as of 2007. Inspected every two years, this dam is regulated by the Indiana Department of Natural Resources and meets state permitting and inspection requirements. The dam features a slide gate outlet and an uncontrolled spillway with a width of 20 feet. With a risk assessment rating of moderate, efforts are made to ensure the dam’s integrity and safety for the surrounding community.

Water resource and climate enthusiasts would find Delaney Creek Dam No. 12 an intriguing structure, showcasing the collaboration between local government and federal agencies in managing flood risk in the region. The dam serves as a vital tool in protecting the area from potential inundation, highlighting the importance of proper maintenance and inspection practices to ensure its continued effectiveness. As climate change continues to impact water resources, structures like Delaney Creek Dam No. 12 play a crucial role in mitigating the risks associated with extreme weather events and safeguarding communities against flooding.

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.
