Summary

Built in 1994, this earth dam stands at a height of 20 feet and stretches for 780 feet, providing a storage capacity of 122 acre-feet. The dam overlooks an unnamed tributary of the Mississinewa River, offering a serene backdrop for outdoor enthusiasts to enjoy activities like fishing, boating, and picnicking.

Despite its low hazard potential, the dam's condition assessment in 2013 indicated poor structural health, prompting a need for maintenance and repairs. The last inspection in 2018 highlighted the importance of regular monitoring and upkeep to ensure public safety and the longevity of the dam. With its uncontrolled spillway and a moderate risk assessment rating, stakeholders are encouraged to implement risk management measures to address any potential safety concerns and uphold the dam's functionality for future generations.

Mississinewa Beach Road Dam's picturesque location and recreational offerings make it a popular destination for locals and visitors alike. As climate change continues to impact water resources, it is crucial for state regulatory agencies like the Indiana Department of Natural Resources to oversee the dam's maintenance, inspections, and enforcement to uphold safety standards and protect the surrounding ecosystem. By staying proactive in risk management and investing in necessary upgrades, this dam can continue to serve as a valuable asset for the community while adapting to the evolving climate challenges.

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.
