Summary

The dam stands at a height of 19 feet with a hydraulic height of 18 feet, and spans a length of 330 feet. It has a storage capacity of 67 acre-feet, with a normal storage level of 44 acre-feet, serving the surrounding area with water for agricultural needs.

This low-hazard dam on the TR-NIOBRARA RIVER is regulated by the Nebraska Department of Natural Resources (DNR) and undergoes regular state inspections to ensure its structural integrity. With a fair condition assessment as of April 2020, the dam is deemed to be in satisfactory operational condition. Despite its low hazard potential, the dam's emergency action plan (EAP) status and risk management measures remain unspecified, highlighting areas for potential improvement in emergency preparedness.

Water resource and climate enthusiasts interested in Bartos Dam 2's design and functionality can appreciate its contribution to local irrigation needs in the area. The dam's location in the Omaha District alongside the Niobrara River underscores its significance in supporting agricultural activities within the region. Ongoing state oversight and maintenance efforts aim to uphold the dam's operational efficiency and safety, ensuring a reliable water supply for the community it serves.

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.
