Summary

Completed in 1980, this dam stands at a height of 18.3 meters and has a storage capacity of 104.7 acre-feet, with a normal storage level of 65.5 acre-feet. Despite its low hazard potential, the dam's condition assessment is poor, highlighting the need for maintenance and potential upgrades to ensure its continued effectiveness in protecting the surrounding area from flooding.

Managed by the Nebraska Department of Natural Resources, Ten Bensel Dam 3484 is subject to state regulation, permitting, inspection, and enforcement to maintain its operational safety and integrity. The dam, constructed using stone core and soil foundation, spans 235 meters in length and covers a surface area of 11.5 acres within Furnas County, Nebraska. While the dam has not undergone significant modifications in recent years, its last inspection in October 2018 identified areas of concern, prompting further evaluation and potential action to address its structural deficiencies.

With its proximity to the Republican River and its vital role in flood risk reduction, Ten Bensel Dam 3484 serves as a key infrastructure for water resource management in the region. As climate change continues to impact weather patterns and increase the frequency and intensity of extreme weather events, the maintenance and upkeep of dams like Ten Bensel Dam are crucial in mitigating potential flood risks and protecting communities downstream. Efforts to improve the condition assessment and implement risk management measures will be essential in ensuring the long-term resilience and effectiveness of this critical water resource infrastructure.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
