Summary

The dam, primarily used for hydroelectric power generation, also serves recreational purposes and is classified as an Earth dam with a height of 17 feet and a length of 2100 feet. The reservoir created by the dam has a storage capacity of 260 acre-feet and covers a surface area of 30 acres, drawing water from the McKenzie River.

Managed by the Federal Energy Regulatory Commission, Carmen Diversion has a low hazard potential and a moderate risk assessment rating. Despite its low hazard potential, the facility undergoes regular inspections to ensure its safety and operational functionality. The dam is equipped with an uncontrolled spillway with a width of 63 feet, capable of handling a maximum discharge of 6000 cubic feet per second. With its strategic location and purposeful design, Carmen Diversion plays a crucial role in meeting the energy needs of the region while offering opportunities for outdoor recreation along the McKenzie River.

As a key feature in the water resource infrastructure of Linn County, Oregon, Carmen Diversion underscores the importance of sustainable water management and renewable energy production. With its blend of functionality and recreational appeal, the facility serves as a testament to the harmonious coexistence of human engineering and natural resources. As climate change continues to impact water resources, facilities like Carmen Diversion will play an increasingly vital role in ensuring a resilient and sustainable water supply for the future.

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.
