Summary

The reservoir, completed in 1950, has a dam height of 24 feet and a storage capacity of 185 acre-feet. Situated along Long Hollow Creek, the reservoir covers a surface area of 24 acres and has a drainage area of 7.4 square miles. The maximum discharge capacity of the reservoir is 410 cubic feet per second, with outlet gates controlled by a needle system.

With its low hazard potential and a condition assessment of "Not Rated," Freezeout Reservoir is a vital resource for agricultural water supply in the region. The reservoir is regulated by the state of Oregon and undergoes regular inspections every six years for maintenance and safety. Although the reservoir has not been modified in recent years, it remains a critical infrastructure for water management in the area, ensuring a reliable supply for irrigation needs. Climate and water resource enthusiasts would find Freezeout Reservoir an intriguing example of sustainable water infrastructure in action, supporting local agricultural practices and contributing to the overall water ecosystem in the region.

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.
