Summary
The reservoir has a height of 21 feet and a storage capacity of 650 acre-feet, with a normal storage level of 454 acre-feet. It is situated on Foley Creek and covers a surface area of 64 acres, serving as a vital resource for water management in the region.
With a low hazard potential and a condition assessment that is currently not rated, Paiute Reservoir offers a reliable water source for agricultural activities in the area. The reservoir is equipped with slide sluice gate outlet gates and has a maximum discharge capacity of 430 cubic feet per second. Despite its modest size, the reservoir plays a crucial role in supporting the local economy and sustaining the surrounding ecosystem.
Managed by the Oregon Water Resources Department, Paiute Reservoir undergoes regular inspections every six years to ensure its structural integrity and safety. While it may not be a large-scale water storage facility, the reservoir's contribution to irrigation and water resource management in the region highlights its significance in addressing the challenges posed by changing climate patterns and water scarcity.

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.
