Alitak Cannery Dam #1 Reservoir Report
Nearby: Alitak Cannery Dam #2
Last Updated: April 5, 2026
Alitak Cannery Dam #1, also known as Cwf Alitak Main Dam, is a historic earth dam located in Kodiak Island, Alaska.
Summary
Built in 1917 by SHANNON & WILSON, this private-owned structure serves as a vital water supply source in the region. With a height of 9 feet and a length of 332 feet, the dam has a storage capacity of 62 acre-feet and covers a surface area of 10 acres.
Despite its age and historical significance, Alitak Cannery Dam #1 faces some challenges in terms of its condition assessment and hazard potential. Inspected last in June 2018, the dam was rated as having poor condition, with a high hazard potential. With an inspection frequency of 3 years, the structure's emergency action plan was last revised in October 2019, highlighting the need for ongoing monitoring and maintenance to ensure its safety and effectiveness.
As water resource and climate enthusiasts, it is crucial to recognize the importance of maintaining and regulating structures like Alitak Cannery Dam #1. With its rich history and significant role in providing water supply, efforts must be made to address its poor condition assessment and high hazard potential. By staying informed and advocating for proper maintenance and risk management measures, we can help safeguard this essential infrastructure for the community and the environment.

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.
