Summary
Built in 1955 by the USDA NRCS, this dam serves the primary purpose of irrigation along the Calf Creek. With a height of 10 feet and a storage capacity of 119.6 acre-feet, the dam plays a crucial role in managing water resources in the region.
Despite its importance, Cox Dam 1-A (Modified) is currently assessed as being in poor condition, with a low hazard potential. The last inspection in May 2012 revealed the need for significant maintenance and improvements. The Nebraska Department of Natural Resources regulates and inspects the dam, ensuring its compliance with state requirements for safety and operation.
As water resource enthusiasts, it is crucial to monitor and advocate for the maintenance and rehabilitation of infrastructure like Cox Dam 1-A (Modified) to ensure the sustainable management of water resources in the area. By working with regulatory agencies and stakeholders, efforts can be made to address the dam's poor condition and improve its functionality for irrigation and flood control along the Calf Creek watershed.

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.
