Summary
14, located in Henry County, Indiana, is a key flood risk reduction structure along the Pink Creek. Constructed in 1971 by the USDA NRCS, this earth dam stands at a height of 38 feet and has a storage capacity of 3200 acre-feet. Despite its significant hazard potential and poor condition assessment, this structure plays a crucial role in protecting the surrounding area from flooding events.
Managed by the local government and regulated by the Indiana Department of Natural Resources, Upper Big Blue River Structure No. 14 undergoes regular inspections to ensure its structural integrity. With a maximum discharge capacity of 1686 cubic feet per second, this dam serves as a vital component in the region's water resource management system. While lacking a spillway, this structure effectively mitigates flood risks for the Stone Quarry Mills area.
For water resource and climate enthusiasts, Upper Big Blue River Structure No. 14 presents a fascinating case study in flood risk reduction infrastructure. With its historical significance, current condition assessment, and high hazard potential, this earth dam highlights the importance of maintaining and monitoring critical structures to safeguard communities and ecosystems from the impacts of extreme weather events.

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.
