Summary
Completed in 1954, this earth dam serves primarily for irrigation purposes along the Jim Creek. With a height of 33 feet and a length of 338 feet, it has a storage capacity of 85 acre-feet and covers a surface area of 6 acres.
Despite its low hazard potential, Caladonia Dam is subject to regular state inspections and enforcement to ensure its safety and functionality. The dam's condition assessment remains unrated as of its last inspection in October 2017, with an inspection frequency of every five years. The dam's emergency action plan status, risk assessment, and inundation maps are currently not updated or prepared, highlighting potential areas for improvement in emergency preparedness.
For water resource and climate enthusiasts, Caladonia Dam stands as a vital infrastructure supporting irrigation in the region, with a strong foundation and design by the Natural Resources Conservation Service. As part of the Omaha District, the dam plays a crucial role in managing water resources and providing a reliable water supply for agricultural activities in the area. Further monitoring and enhancements to emergency preparedness measures could ensure the long-term safety and effectiveness of this essential water management structure.

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.
