Upper Klamath Lake (sometimes called Klamath Lake) is a large, shallow freshwater lake east of the Cascade Range in south central Oregon in the United States. The largest freshwater body in Oregon, it is approximately 20 mi (32 km) long and 8 mi (12.9 km) wide and extends northwest from the city of Klamath Falls. It sits at an elevation of 4140 ft (1262 m).
The lake depth fluctuates due to regulation of its water supply, ranging from 8 ft (2.5 m) to 60 feet (18 m) deep at average levels. The lake level is kept within 1261 to 1264 m above sea level. It is fed by several streams, including the Williamson River and is drained by the Link River, which issues from the south end of the lake. It is connected by a short channel to the smaller Agency Lake to the north. The Upper Klamath National Wildlife Refuge sits along the north edge of the lake.
