Summary
Standing at a height of 33 feet and a length of 838 feet, the dam has a storage capacity of 125.5 acre-feet and covers a surface area of 10.6 acres. Despite its low hazard potential, the dam's condition assessment has been rated as poor, indicating a need for maintenance and repairs.
Managed by the Nebraska Department of Natural Resources, Frank Dam 668 is state-regulated, permitted, inspected, and enforced to ensure its structural integrity and public safety. The dam's primary purpose is flood risk reduction, serving as a crucial infrastructure for protecting the surrounding community from potential flooding events. Although the dam has not been modified in recent years, regular inspections are conducted every 5 years to monitor its condition and safety measures.
With its historical significance as a flood control structure along the North Platte River, Frank Dam 668 plays a vital role in water resource management in the region. Enthusiasts interested in water resources and climate change will find this dam's characteristics and regulatory oversight intriguing, highlighting the importance of maintaining and upgrading aging infrastructure to adapt to changing environmental conditions and protect communities from 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.
