Summary

Established in 1970, this Earth dam structure stands at a height of 25 feet and has a maximum storage capacity of 132 acre-feet. The reservoir covers a surface area of 23.2 acres and is primarily used for recreational purposes, offering opportunities for activities such as fishing, boating, and wildlife observation.

Managed by the Oregon Water Resources Department, Farnam Creek Reservoir is regulated and inspected regularly to ensure its safety and compliance with state regulations. With a significant hazard potential and a moderate risk assessment score, the reservoir's emergency action plan and risk management measures are crucial aspects of its operation. While the dam is uncontrolled, measures are in place to mitigate potential risks and protect the surrounding environment and communities in the event of an emergency.

Located in the city of Swisshome, Farnam Creek Reservoir is a valuable water resource for the region, providing both recreational opportunities and essential storage capacity for water management. With its scenic surroundings and important role in water resource management, the reservoir serves as a vital asset for water and climate enthusiasts interested in sustainable water management practices and the preservation of natural ecosystems.

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.
