Summary
Completed in 2018, this Earth-type dam stands at a height of 30.5 feet and has a storage capacity of 52.3 acre-feet. With a surface area of 3.67 acres and a drainage area of 0.01 square miles, this dam serves a primary purpose of "Other" and is designed to withstand low hazard potential events.
Although the dam has a satisfactory condition assessment as of March 2020, it is subject to regular inspections every 5 years to ensure its structural integrity. The surrounding area, which includes Custer County in Nebraska, relies on this dam for water resource management and climate resilience. With a maximum discharge of 0 cubic feet per second, the Cornhusker Livestock Lagoon Dam plays a crucial role in managing water levels and protecting against potential flooding events in the region.
As an essential infrastructure in the tributary to the South Loup River, the Cornhusker Livestock Lagoon Dam showcases the intersection of private ownership, state regulation, and environmental stewardship. Its completion in 2018 represents a commitment to sustainable water management practices in the face of changing climate patterns and increasing demands on water resources. This dam serves as a vital component of the local ecosystem, offering both protection and resource management capabilities for the community of Pleasanton and beyond.

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.
