Summary

The dam, completed in 1980, stands at a height of 40.9 feet and has a storage capacity of 38.2 acre-feet. Despite its low hazard potential, the dam's condition assessment is poor, highlighting the need for maintenance and possible upgrades to ensure its continued functionality.

Managed by the Nebraska Department of Natural Resources, Wrich Dam 2 is situated on the TR-Missouri River, within the jurisdiction of the state. Although it has not undergone recent modifications, regular inspections are conducted to monitor its structural integrity. With a drainage area of 0.02 square miles and a maximum discharge capacity of 560 cubic feet per second, the dam plays a crucial role in mitigating flood risks in the region.

For water resource and climate enthusiasts, Wrich Dam 2 presents an intriguing case study in dam management and maintenance. As concerns grow over the impact of climate change on water resources, the condition of critical infrastructure like Wrich Dam 2 becomes increasingly important. With a focus on improving its condition assessment and implementing risk management measures, this dam serves as a focal point for ensuring water security and resilience in the face of evolving environmental challenges.

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.
