Summary
Completed in 1994, this earth dam stands at a height of 29 feet, with a hydraulic height of 15 feet and a structural height of 29 feet. Managed by the local government, the dam is regulated by the Nebraska Department of Natural Resources, ensuring that it meets state inspection, enforcement, and permitting requirements. With a storage capacity of 34 acre-feet, Laurel Norris Dam plays a crucial role in protecting the surrounding area from potential flooding events.
Constructed by JEO Johnson Erickson O'Brien, Laurel Norris Dam holds a high hazard potential and is classified as satisfactory in terms of condition assessment as of the last inspection in May 2020. The dam's emergency action plan, though last reviewed in 2016, is essential for ensuring preparedness in case of any unforeseen events. With its strategic location and purposeful design, Laurel Norris Dam serves as a critical infrastructure for water resource management and climate resilience efforts in the region.
As an important piece of flood risk reduction infrastructure in the area, Laurel Norris Dam's role in safeguarding the community from potential water-related disasters cannot be overstated. With its robust design and satisfactory condition, the dam stands ready to face any challenges that may come its way, ensuring the safety and security of the surrounding area. For water resource and climate enthusiasts, Laurel Norris Dam represents a testament to the importance of proactive infrastructure development in mitigating the impacts of extreme weather events and safeguarding communities against the threat of flooding.

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.
