Summary

This private dam, standing at a hydraulic height of 10 feet and structural height of 5 feet, holds a normal storage capacity of 20 acre-feet and a maximum storage of 61 acre-feet. With a surface area of 2300 acres, the dam is situated on Tr-Deer Creek and falls under the jurisdiction of the Washington Dept of Ecology.

Despite its low hazard potential, Baker Lake Dam is regulated and inspected by the state of Washington to ensure its safety and compliance with regulations. The dam is of buttress type, constructed with multi-arch cores on rock and soil foundations, with a length of 110 feet. While the dam has not been rated for condition assessment, it remains an essential infrastructure for irrigation and recreation purposes in the region.

Baker Lake Dam, represented under Congressional District 05, Washington, is a vital component of the local water resource management system. With its modest storage capacity and strategic location, the dam plays a crucial role in maintaining water supply for irrigation activities in the surrounding areas. Enthusiasts of water resources and climate will find Baker Lake Dam to be an interesting case study in private dam ownership and state regulation practices.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
