Information: The dam is 130 feet tall and composed on hydraulic fill. Lake Almanor Dam, spillway, and release point for the North Fork Feather River. The present dam was constructed by Great Western Power, from 1926 to 1927, damming the North Fork of the Feather River and flooding the meadow-filled valley generally known as Big Springs/Big Meadows. In the process, parts of the town of Prattville had to be moved to higher ground, while some structures were flooded over. The reservoir was named for the three daughters of Guy C. Earl, Vice President of Great Western Power: Alice, Martha and Eleanor. [1][2] 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.
