Summary
Built in 1970 by the USDA NRCS, this earth dam reaches a height of 24 feet and spans 575 feet in length. With a storage capacity of 94 acre-feet and a normal storage of 19 acre-feet, the dam serves to protect the surrounding area from potential flooding while also providing valuable water resources for the community.
State-regulated and inspected by the Nebraska Department of Natural Resources, Kaldahl Dam 238 meets all necessary permitting and enforcement requirements to ensure its structural integrity and safety. With a low hazard potential and a condition assessment of "Not Rated," the dam is considered to be in good standing. While specific details about the spillway type and width are not provided, the dam's design and construction by the NRCS reflect a commitment to sustainable water management practices and environmental stewardship.
As a key feature in the local water infrastructure, Kaldahl Dam 238 plays a crucial role in water resource management in Nuckolls County, Nebraska. With a drainage area of 1.3 square miles and a maximum discharge capacity of 353 cubic feet per second, the dam helps to mitigate the impact of heavy rainfall events and ensures the stability of the surrounding ecosystem. For water resource and climate enthusiasts, Kaldahl Dam 238 serves as a prime example of effective water resource management and the importance of infrastructure in safeguarding against natural disasters.

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.
