Summary
Completed in 1984, this earth dam stands at a height of 31 feet, with a structural height of 36 feet and a length of 655 feet, providing flood risk reduction and other purposes for the surrounding area. With a storage capacity of 470 acre-feet and a drainage area of 1.52 square miles, Long Branch P-3 plays a crucial role in managing water flow and ensuring water security in the region.
Despite its low hazard potential and satisfactory condition assessment, Long Branch P-3 undergoes regular inspections every 5 years to ensure its structural integrity and operational efficiency. The dam has a normal storage capacity of 48 acre-feet and can discharge a maximum of 837 cubic feet per second. Its location near TR-KIRKHAM CREEK in HUMBOLDT, Nebraska, demonstrates its strategic importance in water resource management. As a key element in the local water infrastructure, Long Branch P-3 contributes to the overall resilience of the region against climate-related challenges.
With a strong foundation on soil and core made of stone, Long Branch P-3 stands as a testament to effective collaboration between local government agencies and federal entities like the Natural Resources Conservation Service. Its presence reflects a commitment to sustainable water management practices and the protection of communities from potential water-related risks. As water resource and climate enthusiasts, the significance of Long Branch P-3 lies not only in its structural design and operational capabilities but also in its role in safeguarding the environment and enhancing water security for future generations.

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.
