Summary
The dam stands at a height of 34 feet and has a storage capacity of 175 acre-feet, with a normal storage level of 55 acre-feet. With a surface area of 8 acres and a drainage area of 0.8 square miles, the dam plays a critical role in managing water flow and mitigating flood risks in the region.
Managed and regulated by the Nebraska Department of Natural Resources, Bennington Lake Basin 2 has been inspected regularly to ensure its structural integrity and safety. Despite being classified as having a high hazard potential, the dam is in satisfactory condition, meeting regulatory guidelines and emergency preparedness standards. The dam's spillway type, width, and other associated structures are not specified in the data, but its primary purpose, along with flood risk reduction, is categorized as "Other," suggesting a multi-faceted role in water resource management.
With its strategic location and design, Bennington Lake Basin 2 serves as a crucial infrastructure asset in the region, contributing to water resource management, flood control, and environmental protection efforts. As water resource and climate enthusiasts, understanding the technical details and regulatory oversight of such structures is essential for ensuring sustainable water management practices and safeguarding communities against potential hazards. Bennington Lake Basin 2 stands as a testament to collaborative efforts between private owners, regulatory agencies, and engineering firms in managing water resources effectively and responsibly.

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.
