Summary

This earth dam stands at a height of 25 feet, with a hydraulic height of 23 feet and a structural height of 28 feet, completed in 1955. With a storage capacity of 281 acre-feet and a drainage area of 0.7 square miles, Indian Creek 6-A plays a crucial role in managing water flow and reducing flood risks in the region.

Managed by local government authorities, Indian Creek 6-A is situated along the TR-Indian Creek, with a maximum discharge capacity of 2400 cubic feet per second. Despite being categorized as having a low hazard potential, the dam is regularly inspected and maintained to ensure its structural integrity and overall satisfactory condition. With a surface area of 7 acres and a normal storage capacity of 21 acre-feet, this flood risk reduction structure serves as a key component in the water resource management infrastructure of the area.

As a significant part of the flood risk reduction system in Nebraska, Indian Creek 6-A not only provides protection against potential flooding but also contributes to the overall water resource management efforts in the region. With its solid construction, consistent inspections, and low hazard potential, this earth dam stands as a reliable asset in safeguarding communities and ecosystems along Indian Creek. Climate and water resource enthusiasts can appreciate the importance of structures like Indian Creek 6-A in maintaining resilience and sustainability in the face of changing environmental conditions.

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.
