Summary
The reservoir, completed in 1943, has a dam height of 12 feet and a storage capacity of 7500 acre-feet. With a surface area of 956 acres and a maximum discharge of 630 cubic feet per second, Round Barn Reservoir plays a crucial role in water management within the region.
The reservoir is situated on Riddle Creek and is regulated by the Oregon Water Resources Department (OWRD), with state permitting, inspection, and enforcement in place to ensure its safety and functionality. The dam type is classified as earth, with an uncontrolled spillway and slide gates for outlet control. Despite being rated as having a low hazard potential, the reservoir is subject to moderate risk assessment due to its age and potential vulnerabilities.
Round Barn Reservoir, with its strategic location and significant storage capacity, stands as a vital resource for sustaining agricultural operations in the area. As water resource and climate enthusiasts continue to monitor and manage the reservoir, efforts to enhance its safety and efficiency will be crucial in maintaining its role in supporting the local ecosystem and economy.

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.
