Summary

Completed in 1961, this earth dam stands at a height of 29 feet and stretches 851 feet in length, with a storage capacity of 306 acre-feet. The dam is regulated by the Nebraska Department of Natural Resources and undergoes regular inspections to ensure its safety and functionality.

With a significant hazard potential, Pine Lake Dam has been assessed to be in satisfactory condition as of its last inspection in August 2020. It is equipped to handle a maximum discharge of 2347 cubic feet per second and covers a surface area of 16 acres with a drainage area of 0.6 square miles. While there are no spillways or outlet gates associated with the dam, it remains a popular destination for recreational activities in the area.

Congressional District 01, Nebraska representative Jeff Fortenberry oversees Pine Lake Dam, situated in the Kansas City District under the jurisdiction of the US Army Corps of Engineers. As a vital water resource in the region, the dam plays a crucial role in providing recreational opportunities while ensuring the safety and well-being of the surrounding community. With its impressive history and ongoing maintenance efforts, Pine Lake Dam stands as a testament to effective water management practices in the state of Nebraska.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
