Summary
The earth dam, standing at a height of 27 feet with a structural height of 37 feet, was completed in 1959 and has a storage capacity of 316 acre-feet. With a surface area of 22.1 acres and a drainage area of 1.55 square miles, the reservoir is fed by Beaver Creek and has a maximum discharge capacity of 450 cubic feet per second.
The reservoir's low hazard potential and "Not Rated" condition assessment indicate its overall stability and safety. It is inspected every 6 years, with the last inspection conducted in October 2019. The outlet gates consist of a slide (sluice gate) for water release. Situated within the Portland District, Palmer Reservoir plays a vital role in the local irrigation system, supporting agricultural activities in the region. The reservoir's strategic location in Paulina, Oregon, demonstrates its importance in water resource management and climate resilience efforts.
As a key water resource infrastructure in Oregon, Palmer Reservoir contributes to the sustainability of agricultural practices in the area. Its presence along Beaver Creek underscores the significance of efficient water storage and management for irrigation purposes. Despite its low hazard potential, regular inspections and maintenance ensure the reservoir's continued functionality and safety for both the environment and surrounding communities. With its rich history dating back to 1959, Palmer Reservoir remains a crucial component of the region's water supply and climate adaptation strategies.

Dam Data Reference
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.
