Summary
Completed in 1981, this earth dam stands at a height of 41 feet and spans a length of 1121 feet, providing a maximum storage capacity of 1048 acre-feet. With a normal storage capacity of 146 acre-feet and a drainage area of 3.9 square miles, Long Branch 41 plays a vital role in managing water resources in the region.
Managed by the local government and regulated by the Nebraska Department of Natural Resources, Long Branch 41 has a low hazard potential and is deemed to be in satisfactory condition as of the last assessment in 2018. The dam's primary purpose is flood risk reduction, and it operates under the oversight of the Natural Resources Conservation Service. Despite its critical role in flood control, Long Branch 41 has not undergone substantial modifications since its completion and does not fall under the jurisdiction of the US Army Corps of Engineers.
For water resource and climate enthusiasts, Long Branch 41 serves as a notable example of successful infrastructure designed to protect communities from potential flooding events. Its strategic location, design features, and regulatory oversight highlight the importance of effective water management practices in mitigating natural hazards and safeguarding the environment. As climate change continues to impact precipitation patterns and water availability, structures like Long Branch 41 play a crucial role in ensuring the resilience and sustainability of water resources in the face of evolving climatic conditions.

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.
