Summary

Completed in 1967, this earth dam stands at a height of 27 feet with a structural height of 33 feet and a length of 1440 feet. It serves the primary purpose of flood risk reduction for the area, with a storage capacity of 2036 acre-feet and a drainage area of 6.6 square miles.

The dam has a low hazard potential and is in satisfactory condition, last inspected in October 2020 with a 5-year inspection frequency. With a normal storage capacity of 179 acre-feet and a maximum discharge of 904 cubic feet per second, Big Indian Creek 10-A plays a crucial role in managing water resources in the region. Located along the TR-Big Indian Creek, this structure is essential in protecting the surrounding area from potential flooding events and ensuring water security for the local community.

Managed by local government authorities, Big Indian Creek 10-A is a key component in the water infrastructure of the region, supported by the Natural Resources Conservation Service. With its strategic location and effective design, this dam stands as a testament to the importance of flood risk reduction and water resource management in mitigating the impacts of extreme weather events and climate change in the area.

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.
