Summary
Completed in 1970, this earth dam stands at 23 feet high and spans 347 feet in length, with a storage capacity of 265 acre-feet. The dam is situated on the TR-Little Blue River and is regulated by the Nebraska Department of Natural Resources, ensuring proper inspection, permitting, and enforcement measures are in place.
Despite its importance in providing irrigation water, Skalka Dam 239 currently has a poor condition assessment and a low hazard potential. The last inspection in 2016 revealed this concerning status, prompting the need for maintenance and potential improvements to ensure the dam's safety and functionality. While the dam has not been modified in recent years, regular inspections every 5 years are crucial to monitoring its structural integrity and addressing any issues that may arise.
As a significant water management structure in the region, Skalka Dam 239 plays a crucial role in supporting agricultural activities and water supply. With its strategic location on the Little Blue River and its vital function in irrigation, efforts to maintain and improve the dam's condition are essential to safeguarding its long-term effectiveness and mitigating potential risks. For water resource and climate enthusiasts, staying informed about the status of Skalka Dam 239 is crucial for understanding the intersection of water management, infrastructure, and environmental stewardship in Nebraska.

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.
