Summary

Completed in 2005, the dam serves multiple purposes, including flood risk reduction and other water resource management functions. It has a storage capacity of 81.7 acre-feet and covers a surface area of 5.4 acres, drawing water from the TR-PLUM CREEK river or stream.

Managed by the Nebraska Department of Natural Resources (DNR), Mccune Dam is regulated, inspected, and enforced by state authorities to ensure its safety and functionality. Despite being classified as low hazard potential, with a condition assessment of "Not Rated," the dam undergoes regular inspections every 5 years to maintain its integrity and address any potential risks. The facility has not experienced any major modifications or incidents since its construction.

With its strategic location and purposeful design, Mccune Dam plays a crucial role in water resource management and flood control efforts in the Pawnee County area. As a key structure in the local watershed, the dam contributes to the overall resilience and sustainability of the region's water supply and ecosystem. Enthusiasts of water resources and climate change will find Mccune Dam to be a fascinating example of innovative engineering and responsible stewardship in the face of evolving environmental challenges.

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.
