Summary
Completed in 1949, this earth dam stands at a height of 26 feet and spans a length of 320 feet, offering a serene surface area of 9.8 acres. With a primary purpose of recreation, the reservoir provides a tranquil escape for water and climate enthusiasts to enjoy activities such as fishing, boating, and wildlife observation.
Located along the Middle Fork of the John Day River, Bates Reservoir boasts a maximum storage capacity of 100 acre-feet and a normal storage level of 32 acre-feet. Although classified as having low hazard potential, the dam undergoes regular inspections by the Oregon Water Resources Department to ensure its structural integrity. The surrounding area is rich in natural beauty, offering visitors a chance to appreciate the harmonious coexistence of human-made infrastructure with the picturesque landscape of the Pacific Northwest.
Bates Reservoir serves as a testament to the harmonious balance between human recreation and environmental conservation. With its modest size and low hazard potential, this hidden gem in Oregon provides a peaceful retreat for those seeking to connect with nature and enjoy the beauty of the John Day River watershed. Whether for a leisurely day of fishing or a quiet paddle on the calm waters, Bates Reservoir offers a unique opportunity to appreciate the intersection of water resources and climate in a tranquil setting.

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.
