Summary
The dam, classified as an earth dam with buttress core types, stands at a height of 13 feet and stretches 1,500 feet in length. It has a storage capacity of 550 acre-feet and covers a surface area of 185 acres. The dam, built in 1967, underwent a structural modification in the same year to enhance its functionality.
Despite being rated as having a significant hazard potential and a moderate risk assessment, the dam's condition assessment remains unrated. The last inspection of the Beluga Lake Dam took place in July 2018, with an inspection frequency set at every three years. The dam's emergency action plan was last revised in January 2019. With its uncontrolled spillway and a spillway width of 4 feet, the dam plays a crucial role in managing water resources and supporting recreational activities in the area.
Water resource and climate enthusiasts interested in the management of dams and their impact on fish and wildlife habitats would find the Beluga Lake Dam an intriguing subject. As a key structure in the region, the dam's risk assessment and emergency preparedness are essential considerations in ensuring the safety and sustainability of the surrounding environment. With its location in the Kenai Peninsula, Alaska, the Beluga Lake Dam stands as a testament to the intricate balance between human development and ecosystem preservation in a changing climate.

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.
