Summary
Completed in 1970, this Earth-type dam stands at a height of 31 feet and has a maximum storage capacity of 124 acre-feet, serving purposes of flood risk reduction and other water resource management objectives.
With a satisfactory condition assessment and low hazard potential, Bergmann Dam covers a surface area of 5 acres and has a drainage area of 1.6 square miles. Its design includes a stone core and soil foundation, with a structural height of 34 feet and a hydraulic height of 30 feet. The dam's maximum discharge capacity reaches 430 cubic feet per second, ensuring efficient water control and management for the surrounding area.
Situated along TR-INDIAN CREEK, this dam plays a crucial role in maintaining water resources in the region, with regular inspections conducted every 5 years to ensure its structural integrity and operational efficiency. As a vital component of the local water infrastructure, Bergmann Dam stands as a testament to effective water resource management practices in Nebraska, offering a sustainable solution for flood risk reduction and water storage needs in the area.

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.
