Summary
This earth dam stands at 30 feet tall with a structural height of 34 feet and a length of 775 feet. It has a NID storage capacity of 492.1 acre-feet and serves the primary purpose of flood risk reduction in the area. With a normal storage capacity of 47.6 acre-feet and a maximum discharge of 2279 cubic feet per second, this dam plays a crucial role in managing water resources in the region.
Managed by the Nebraska Department of Natural Resources, Big Indian Creek 12-A is inspected every three years with a satisfactory condition assessment as of June 2018. The dam is considered to have a significant hazard potential with a surface area of 9.4 acres and a drainage area of 2.53 square miles. Located on the TR-Sicily Creek, this structure is designed to mitigate flooding risks and protect the surrounding community in Wymore. The dam's core consists of stone with a foundation in soil, providing essential hydraulic infrastructure for water management in the area.
As part of the Omaha District, the Big Indian Creek 12-A dam is a key asset in the region's water resource and climate management efforts. With its critical role in flood risk reduction and its strategic location on a major stream, this dam showcases the importance of infrastructure in safeguarding communities against natural disasters. As climate change continues to impact water resources, structures like Big Indian Creek 12-A play a vital role in ensuring the resilience and sustainability of the region's water management systems.

Dam Data Reference
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.
