Summary
Built in 1965, this dam serves as a vital hydroelectric facility on the Eklutna River, with a primary purpose of generating power through its Earth-type design. Standing at a height of 41 feet and with a storage capacity of 240,000 acre-feet, this dam plays a crucial role in water resource management in the region.
With a high hazard potential and a satisfactory condition assessment as of December 2018, Eklutna Dam is subject to regular inspections to ensure its structural integrity and safety. The dam boasts a spillway width of 18 feet and a maximum discharge capacity of 4000 cubic feet per second, offering protection against potential flooding events. Moreover, its location in a state-regulated jurisdiction with permitting, inspection, and enforcement mechanisms in place ensures that it meets safety guidelines and environmental standards.
For water resource and climate enthusiasts, Eklutna Dam presents a fascinating example of sustainable energy generation and water management in the Alaskan landscape. Its contribution to the region's hydroelectric power supply, combined with its strategic location on the Eklutna River, highlights the importance of responsible infrastructure development in balancing environmental conservation with societal needs. As a key player in Alaska's water infrastructure, Eklutna Dam stands as a testament to the ongoing efforts to harness natural resources while safeguarding the surrounding ecosystem for future generations.

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.
