Summary
Constructed in 1967, this earth dam stands at a height of 17 feet and has a storage capacity of 146 acre-feet. The reservoir covers a surface area of 21 acres and serves a drainage area of 2.88 square miles, with a maximum discharge capacity of 450 cubic feet per second.
Managed by the Natural Resources Conservation Service, Rohde Reservoir is regulated by the Oregon Water Resources Department, ensuring that state permitting, inspection, and enforcement are all in place. The dam's hazard potential is rated as low, and it has a needle outlet gate for water release. Despite its age, the condition of the reservoir has not been formally assessed, but regular inspections are conducted every six years to monitor its integrity and safety.
With its tranquil location along Ash Swale, a tributary to a larger river system, Rohde Reservoir serves as a vital water source for agricultural irrigation in the region. The reservoir's contribution to water management in Polk County, Oregon, underscores the importance of sustainable water resource practices in the face of climate variability and increasing demands on water supplies.

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.
