John C. Boyle Reservoir was an artificial impoundment behind John C. Boyle Dam on the Klamath River in the U.S. state of Oregon. The lake was 16 miles (26 km) west-southwest of Klamath Falls along Oregon Route 66.
The dam stood at about river mile (RM) 225 or river kilometer (RK) 362, about 10 miles (16 km) by river downstream of the community of Keno. Spencer Bridge carried the highway over the lake at about its midpoint.
Water from the reservoir was diverted through a sluice to the Boyle Powerhouse, about 5 miles (8 km) downstream of the dam. Fluctuations of up to 3 feet (0.9 m) daily in the reservoir level occurred as water was added for storage or diverted for power generation.
