Summary

This dam, standing at a height of 15.9 feet and spanning 410 feet in length, plays a crucial role in managing the water resources of the TR-Advent Creek. With a storage capacity of 52.2 acre-feet, Jensen Dam 6750 serves as a key infrastructure for regulating water flow and protecting the surrounding areas from potential flooding.

Despite its importance, Jensen Dam 6750 is currently rated as having a poor condition assessment, indicating the need for maintenance and improvements to ensure its long-term functionality. The dam has a low hazard potential, but regular inspections and enforcement by the Nebraska Department of Natural Resources are in place to uphold safety standards. With a drainage area of 1.14 square miles and a normal storage capacity of 17.5 acre-feet, this dam remains a vital component in water resource management for the region.

As climate change continues to impact water resources and increase the frequency of extreme weather events, the maintenance and upkeep of dams like Jensen Dam 6750 become increasingly critical. With proper regulation, inspection, and enforcement measures in place, this dam will continue to play a significant role in mitigating flood risks and ensuring water security for the community and environment it serves.

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.
