Alitak Cannery Dam #3 Reservoir Report
Last Updated: April 5, 2026
Alitak Cannery Dam #3, also known as Cwf Alitak Dam, is a privately owned rockfill dam located in Alitak Cannery, Kodiak Island, Alaska.
Summary
Built in 1964 by SHANNON & WILSON, this dam serves as a crucial water supply source in the region. With a height of 8 feet and a length of 291 feet, the dam has a storage capacity of 51 acre-feet and a maximum discharge capacity of 350 cubic feet per second.
Despite its low hazard potential and being classified as "Not Rated" in terms of condition assessment, Alitak Cannery Dam #3 is subject to state permitting, inspection, and enforcement regulations. The dam's primary purpose is water supply, and it stands as a testament to the engineering expertise that went into its design and construction. Situated in a picturesque location at 56.9 latitude and -154.24 longitude, this dam plays a vital role in supporting water needs in the surrounding area.
While the dam has not been significantly modified since its completion, it remains a key infrastructure asset for water resource management in Alitak Cannery. The dam's emergency action plan status, inundation maps, and risk assessment details are not currently available, suggesting a need for updated emergency preparedness measures. As a critical piece of infrastructure in Alaska, Alitak Cannery Dam #3 underscores the importance of sustainable water resource management and climate resilience efforts 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.
