Lake Almanor - LocationPlumas County, California

 

Lake Almanor is a large reservoir in northwestern Plumas County, northeastern California. The reservoir has a capacity of 1,308,000 acre feet (1.613×109 m3) and a maximum depth of about 90 feet. It is formed by Canyon Dam on the North Fork of the Feather River, as well as Benner and Last Chance Creeks, Hamilton Branch, and various natural springs.

 

The dam is 130 feet tall and composed of hydraulic fill.

The first dam was completed by Great Western Power in 1914[1] as part of the Upper North Fork Feather River Project, damming the North Fork of the Feather River and flooding the meadow-filled valley generally known as Nakam Koyo/Big Meadows/Big Springs, a longstanding Yamani Maidu village site.[2][3] When the dam was built, Maidu families still living in the vicinity were displaced while parts of the town of Prattville had to be moved to higher ground, leaving multiple structures flooded over. The reservoir was named for the three daughters of Guy C. Earl, Vice President of Great Western Power: Alice, Martha and Eleanor.[4][5] The present dam, which more than doubled the size was constructed by Great Western Power from 1926 to 1927.

The dam is now owned by Pacific Gas and Electric Company. PG&E uses it for hydroelectricity production, but the lake is also a popular recreation area, with fishing, boating, water skiing, swimming and camping available.
