Summary

Completed in 1935, this public utility structure stands at a height of 30 feet and has a storage capacity of 65,000 acre-feet. The dam spans 34,100 feet and has a surface area of 3,050 acres, serving as a vital water resource for the region.

Managed by the Nebraska Department of Natural Resources and regulated by the Federal Energy Regulatory Commission, Sutherland plays a crucial role in water management and energy production in the area. With a high hazard potential and a risk assessment rating of very high, the dam requires regular inspections and maintenance to ensure its structural integrity and safety. The dam's emergency action plan was last revised in 2017, highlighting the importance of preparedness in case of unforeseen events.

As a key feature on the North and South Platte rivers, Sutherland Dam serves as a cornerstone for water resource management and hydroelectric power generation in Nebraska. Its controlled spillway, vertical lift outlet gates, and stone core construction demonstrate its resilience and functionality in the face of changing climate conditions. For water resource and climate enthusiasts, Sutherland Dam represents a blend of history, engineering, and environmental stewardship in the heart of the Midwest.

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.
