Summary
Built in 1943, this buttress-type dam stands at a height of 15 feet and stretches 60 feet in length, with a storage capacity of 2260 acre-feet. The dam serves the primary purpose of water supply, helping to meet the water needs of the local community in the city of ADAK NAVAL BASE.
Managed by the Local Government, Bonnie Rose Lake Dam is regulated, permitted, inspected, and enforced by the Alaska Department of Natural Resources (AKDNR). The dam has a spillway width of 15 feet and a maximum discharge capacity of 1000 cubic feet per second, with a significant hazard potential. While the dam's condition assessment is not rated, it undergoes inspections every three years to ensure its structural integrity and safety. With a moderate risk assessment rating, the dam plays a crucial role in water resource management and climate resilience efforts in the region.
Overall, Bonnie Rose Lake Dam stands as a key water infrastructure asset in Alaska, providing essential water supply services to the local community. As a regulated and inspected structure, the dam ensures the safety and reliability of water resources in the area. With its significant storage capacity and moderate risk assessment, the dam contributes to the sustainable management of water resources and climate adaptation strategies in the region.

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.
