Summary

Completed in 1960, this dam stands at a height of 18.3 feet and has a capacity of 102.8 acre-feet, with a normal storage capacity of 12.6 acre-feet. The dam spans 430 feet in length and covers a surface area of 5.5 acres, serving the purpose of mitigating flood risks in the region.

Managed by the Nebraska Department of Natural Resources, General Agricultural Services Dam is regulated, inspected, and enforced by state authorities to ensure its structural integrity and safety. With a low hazard potential and a condition assessment that is not rated, this dam plays a crucial role in protecting the surrounding area from potential flooding events. The dam's emergency action plan status, risk assessment, and risk management measures are currently unspecified, indicating a need for further evaluation and planning to enhance its resilience and preparedness for emergencies.

As a key infrastructure in flood risk reduction efforts in Nuckolls County, Nebraska, General Agricultural Services Dam serves as a vital resource for water management and climate resilience in the region. With its strategic location, design features, and state oversight, this dam plays a crucial role in safeguarding the community against floods and ensuring the sustainable management of water resources for agricultural and environmental purposes.

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.
