Alitak Cannery Dam #4 Reservoir Report
Last Updated: April 5, 2026
Alitak Cannery Dam #4, also known as Cwf Alitak Dam, is a rockfill dam located in Kodiak Island, Alaska.
Summary
Built in 1964 by SHANNON & WILSON, this privately owned structure serves as a water supply source for the Alitak Cannery area. With a height of 12 feet and a hydraulic height of 6 feet, the dam has a maximum storage capacity of 51 acre-feet and spans a length of 380 feet.
Despite being categorized as having a low hazard potential, the condition of Alitak Cannery Dam #4 has not been officially rated. The last inspection of the dam took place in May 2006, and it is not subject to state regulation or oversight. While the dam is equipped with outlet gates, details on its spillway type and maximum discharge capacity are not provided. As a vital water resource infrastructure in the region, the dam plays a crucial role in maintaining the water supply for the Alitak Cannery community.
Given its importance for water supply purposes, it is essential that Alitak Cannery Dam #4 continues to be monitored and maintained regularly to ensure its structural integrity and functionality. With its historical significance and role in supporting the local community, the dam serves as a testament to the engineering expertise of its designers and the importance of water resource management in the Alaskan wilderness.

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.
