Summary
Completed in 1959, this reservoir has a height of 15 feet and a storage capacity of 115 acre-feet. With a surface area of 45 acres and a drainage area of 4.9 square miles, the reservoir serves as a crucial water source for the region, drawing from the Lost River.
Managed by the Oregon Water Resources Department, the Keno Reservoir is regulated, inspected, and enforced to ensure its structural integrity and operational efficiency. Despite being classified as having a low hazard potential, the dam is monitored regularly with a six-year inspection frequency. The outlet gates are equipped with slide (sluice gate) mechanisms to control water flow, with a maximum discharge capacity of 200 cubic feet per second.
Enthusiasts of water resources and climate in the area can appreciate the significance of the Keno Reservoir in supporting agricultural activities and maintaining water supply stability. With its strategic location and design features, this reservoir plays a vital role in the region's water management system while adhering to state regulations and safety standards for dam structures.

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.
