John C. Boyle Reservoir is an artificial impoundment behind John C. Boyle Dam on the Klamath River in the U.S. state of Oregon. The lake is 16 miles (26 km) west-southwest of Klamath Falls along Oregon Route 66.[1]

The dam is at about river mile (RM) 225 or river kilometer (RK) 362, about 10 miles (16 km) by river downstream of the community of Keno.[4] Spencer Bridge carries the highway over the lake at about its midpoint.[4]

Water from the reservoir is diverted through a sluice to the Boyle Powerhouse, about 5 miles (8 km) downstream of the dam.[5] Fluctuations of up to 3 feet (0.9 m) daily in the reservoir level occur as water is added for storage or diverted for power generation.[6]

History

The California–Oregon Power Company (COPCO), which later merged with Pacific Power, a future subsidiary of PacifiCorp, built the dam in the mid-1950s as part of the multi-dam Klamath River Hydroelectric Project.[7] Meant primarily to generate hydroelectricity, the reservoir can hold up to 4,200 acre feet (5,200,000 m3) of water.[1] Originally called Big Bend Reservoir, it was renamed in 1962 for John C. Boyle, COPCO's vice president, general manager, and chief engineer.[7]

The Boyle dam is one of four Klamath River dams that may be removed as early as 2020 if the United States Congress eventually agrees.[8] The other three, all owned by PacifiCorp and all in California, are Iron Gate, Copco 2, and Copco 1.[9] A tentative agreement reached in 2009 by major stakeholders, including PacifiCorp, would remove the dams to restore salmon runs blocked below Iron Gate for about a century.[9]

Recreation

The reservoir supports largemouth bass ranging from 12 to 16 inches (30 to 41 cm), which can be fished for by boat or from the bank.[6] Other fish found in the lake include black crappie, white crappie, yellow perch, brown bullhead, and pumpkinseed sunfish.[6]

Topsy Recreation Site, maintained by the Bureau of Land Management, has a campground, a boat launch, a dock, and a fishing pier at J. C. Boyle Reservoir. Swimming, picnicking, and bird-watching are among recreational activities in addition to camping and fishing.[10][11]
