Summary
Completed in 1968, this structure stands at a height of 36 feet with a hydraulic height of 35 feet and a structural height of 42 feet. With a storage capacity of 550 acre-feet and a normal storage of 107 acre-feet, this dam plays a crucial role in managing water flow in the region.
The dam, built on Big Indian Creek, covers a surface area of 17 acres and serves a drainage area of 1.4 square miles. Its maximum discharge capacity reaches 836 cubic feet per second, ensuring effective flood control measures. With a low hazard potential and a satisfactory condition assessment as of May 2019, this structure is regularly inspected by the Nebraska Department of Natural Resources to maintain its functionality and safety standards. The dam's primary purpose is flood risk reduction, highlighting its importance in safeguarding the community against potential water-related disasters.
Owned and regulated by the local government with oversight from the Nebraska DNR, Big Indian Creek 6-B embodies a collaborative effort to protect the area from flooding events. Its strategic location in the Omaha District further enhances its significance in the regional water resource management system. As a key component of the state's flood control infrastructure, this dam stands as a testament to effective engineering and environmental stewardship in ensuring water security and climate resilience for the surrounding communities.

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.
