Summary
Built in 1962, this Buttress-type dam stands at a structural height of 9 feet and has a hydraulic height of 7 feet. With a capacity to store 1800 acre-feet of water, the dam covers a surface area of 400 acres and can discharge up to 35 cubic feet per second. Despite being rated as low hazard potential, the dam's condition assessment is currently listed as "Not Rated".
Situated in a pristine natural setting, Big Kitoi plays a crucial role in water resource management for the region. The dam is equipped with inspection, enforcement, and permitting protocols in place, ensuring its safe operation. With Don Young (R) as the representative for the area, the dam serves as a vital infrastructure for maintaining water supply to the surrounding communities. While the dam's Emergency Action Plan (EAP) readiness is not specified, its risk management measures and inundation maps preparedness remain undisclosed.
Water resource and climate enthusiasts will find Big Kitoi an intriguing structure that showcases the importance of sustainable water management practices in Alaska. As a state-regulated dam with a history dating back to the early 1960s, it highlights the critical role of infrastructure in safeguarding water resources in remote regions. With its low hazard potential and not rated condition assessment, there is a need for further evaluation and monitoring to ensure the long-term safety and effectiveness of this essential water supply facility in Kodiak Island.

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.
