Summary

Constructed in 1956 by the USDA NRCS, this Earth-type dam stands at a height of 22 feet and has a hydraulic height of 20 feet. With a normal storage capacity of 14.5 acre-feet and a maximum storage of 233.5 acre-feet, the dam serves to mitigate the risk of flooding in the area.

Managed by the Nebraska Department of Natural Resources, Indian Creek 3-A has a low hazard potential and is deemed to be in satisfactory condition based on the latest assessment in June 2020. The dam has a drainage area of 0.53 square miles and a maximum discharge capacity of 1400 cubic feet per second. Despite its age, the dam continues to play a crucial role in protecting the surrounding community from the threat of flooding, highlighting the importance of effective water resource management in the region.

In the event of an emergency, the dam's emergency action plan (EAP) status and risk assessment information are currently not available. However, regular inspections are conducted, with the most recent inspection taking place in June 2020. With its strategic location along the TR-Indian Creek, Indian Creek 3-A stands as a vital infrastructure for flood control in the area, showcasing the ongoing efforts to ensure the safety and resilience of water resources in Nebraska.

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.
