Summary
Built in 1955, this earth dam stands at a height of 14 feet and spans 520 feet in length. With a maximum storage capacity of 110.2 acre-feet and a normal storage of 46.8 acre-feet, the dam plays a crucial role in managing water resources in the area.
Despite its low hazard potential, Cline South Dam is currently assessed to be in poor condition as of the last inspection in April 2017. The dam is under the jurisdiction of the Nebraska Department of Natural Resources (DNR) and is subject to state regulation, permitting, inspection, and enforcement. As a key component of flood risk reduction efforts, the dam's maintenance and upkeep are vital to ensuring the safety and resilience of the surrounding communities in Franklin County.
With a drainage area of 7.52 square miles and a maximum discharge capacity of 1835 cubic feet per second, Cline South Dam serves as a critical infrastructure for water resource management in the region. As climate change continues to impact precipitation patterns and extreme weather events, the importance of maintaining and improving the resilience of dams like Cline South becomes increasingly evident for ensuring the safety and sustainability of water resources in Nebraska.

Dam Data Reference
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.
