Summary
Built in 1966 by the USDA NRCS, this structure stands at a height of 25 feet and spans 775 feet in length, serving primarily for flood risk reduction along the Big Indian Creek. With a storage capacity of 547 acre-feet and a drainage area of 1.3 square miles, this dam plays a crucial role in mitigating potential flooding in the region.
Managed by the Nebraska Department of Natural Resources, Big Indian Creek 8-B-1 has a low hazard potential and is deemed to be in satisfactory condition as of its last inspection in June 2018. While the dam has not undergone modifications in recent years, it is subject to regular state inspection, enforcement, and permitting to ensure its continued functionality and safety. With a maximum discharge capacity of 905 cubic feet per second, this structure is designed to handle significant water flow during periods of high rainfall or snowmelt, protecting downstream areas from potential inundation.
Located in Diller, Nebraska, this earth dam serves as a vital piece of infrastructure in the area's water resource management and climate resilience efforts. With its strategic placement along the Big Indian Creek and its solid construction by the USDA NRCS, Big Indian Creek 8-B-1 stands as a testament to the collaborative efforts between local government agencies and federal entities in safeguarding communities against the impacts of flooding and ensuring the sustainable use of water resources in the region.

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.
