Summary

Completed in 1945, this earth dam stands at 21 feet high and spans 298 feet in length, with a storage capacity of 221 acre-feet. Despite being classified as low hazard potential, the dam's condition assessment remains unrated, with the last inspection conducted in 1993.

The dam, situated along the Bean Blossom Creek, has a normal storage capacity of 57 acre-feet and a drainage area of 1.67 square miles. Its maximum discharge capability is reported to be 567 cubic feet per second, emphasizing its role in flood control and water resource management in the region. While lacking detailed information on spillway type and emergency action plans, the dam continues to serve as a crucial recreational site for locals and visitors alike.

For water resource and climate enthusiasts, Bean Blossom Dam represents a vital piece of infrastructure in Indiana's water management system. As discussions around dam safety and maintenance continue, the dam's role in providing recreational opportunities and flood control remains essential. With its historical significance and ongoing relevance in the region, Bean Blossom Dam serves as a focal point for understanding the intersection of water resources, infrastructure development, and environmental stewardship in the state.

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.
