Summary
Built in 1960, this earth dam stands at a height of 10.6 feet and has a storage capacity of 59.8 acre-feet, with a normal storage capacity of 30.7 acre-feet. Despite its low hazard potential, the dam is currently assessed to be in poor condition as of July 2019.
Situated along TR-ANTELOPE CREEK, this structure serves an important role in the local water resource management system. While the dam has not experienced any modifications in recent years, it is subject to state regulation, inspection, and enforcement by the Nebraska Department of Natural Resources. With a drainage area of 0.74 square miles and a surface area of 11.4 acres, Barkers Spring Allot 3 plays a crucial role in maintaining water levels and supporting local ecosystems.
As climate change continues to impact water resources across the globe, the maintenance and upkeep of structures like Barkers Spring Allot 3 will be essential in ensuring the sustainability of water sources for both human and environmental needs. It is imperative that proper monitoring and management practices are in place to address the poor condition of the dam and mitigate any potential risks associated with its operation.

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.
