Summary

Built in 1962 by the Natural Resources Conservation Service and the US Navy, this Earth-type dam serves the primary purpose of flood risk reduction along Boggs Creek. With a height of 26 feet and a length of 890 feet, the dam has a storage capacity of 6,740 acre-feet and covers a surface area of 102 acres.

The dam features an uncontrolled spillway with a width of 870 feet, allowing for a maximum discharge of 21,982 cubic feet per second. Despite its significant hazard potential, Lake Gallimore Dam is currently in satisfactory condition, as assessed during the last inspection in June 2021. The dam is not regulated by the state of Indiana and has not been modified since its completion, reflecting its stable and reliable infrastructure for managing water resources in the region.

Water resource and climate enthusiasts will appreciate the strategic design and operational efficiency of Lake Gallimore Dam in mitigating flood risks along Boggs Creek. As a key component of the flood control system in Martin County, Indiana, this dam exemplifies the collaboration between federal agencies and local stakeholders to ensure the safety and resilience of the surrounding community. Its location, capacity, and maintenance history make Lake Gallimore Dam a noteworthy structure for those interested in sustainable water management practices and climate adaptation strategies.

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.
