Summary

5, also known as Delaney Park Lake, is a significant earth dam located in Millport, Indiana along the Muscatatuck River. Constructed in 1974 by the USDA NRCS, this dam stands at a height of 43 feet and serves primarily for flood risk reduction. With a storage capacity of 2,314 acre-feet and a drainage area of 2.77 square miles, this dam plays a crucial role in managing water flow in the region.

The dam's structural height of 45 feet and fair condition assessment indicate its importance in mitigating flood hazards in the area. Despite not having a spillway, Delaney Creek Dam No. 5 has a maximum discharge capacity of 3,737 cubic feet per second. The dam's location in Washington County, Indiana, highlights its strategic position for protecting downstream communities and infrastructure from potential flood events.

With a significant hazard potential and high-risk assessment, Delaney Creek Dam No. 5 underscores the importance of regular inspections and maintenance to ensure its continued effectiveness in flood risk reduction. As a key structure owned by the local government and regulated by the Indiana Department of Natural Resources, this dam showcases the collaborative efforts aimed at safeguarding water resources and enhancing climate resilience in the region.

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.
