Geology
Fish Lake is located between two volcanoes: Mount McLoughlin to the north and Brown Mountain to the south. Two-thousand-year-old andesite lava flows erupted from Brown Mountain surround Fish Lake's southern shore.[3][4]
History
Fish Lake was originally a small natural lake.[5][6] In 1898, the Fish Lake Water Company was established to help irrigate the Rogue Valley. The company proposed to enlarge Fish Lake and nearby Fourmile Lake for added water storage. The temporary Fish Lake Dam was constructed between 1902 and 1908. In 1906, Fourmile Lake Dam was constructed. The two lakes were connected in 1915 by the Cascade Canal, bringing water from Fourmile Lake in the Klamath River watershed over the Cascade Divide to Fish Lake, to supplement Little Butte Creek. The temporary dam was later replaced by a permanent earthfill dam.[7] The dam was modified again in 1922.[8] In 1955, a new spillway was constructed. An auxiliary spillway was added in 1996.[3] The lake is now about three times its original size.[5]
Statistics
Fish Lake has an average surface area of 483 acres (1,950,000 m2),[6] an average volume of 7,836 acre-feet (9,666,000 m3),[9] and a 20-square-mile (52 km2) drainage basin.[10] It has an average depth of 18 feet (5.5 m), and a maximum depth of 31 feet (9.4 m).[6] Fish Lake Dam stands 50 feet (15 m) tall and 960 feet (290 m) long.[3]
