Lake Almanor

Lake Almanor is a reservoir in Plumas County in northeastern California with views of Lassen Peak and Dyer Mountain. The water surface extends across roughly 111 square kilometers with about 84 kilometers of shoreline.

Great Western Power completed the first dam in 1914 and flooded the North Fork Feather River valley. Yamani Maidu families lost their village and had to leave the area.

The name combines the first syllables of Alice, Martha, and Eleanor, three daughters of Vice President Guy C. Earl. Today families use the water for swimming and boating, while anglers seek out the shores and coves.

In summer the water warms to about 20 to 21 degrees Celsius (68 to 70 degrees Fahrenheit) and works well for swimming and water sports. The shore areas are easily accessible for swimmers and boaters.

The Almanor Fishing Association runs California's oldest fish-rearing program and releases about 50,000 Eagle Lake Trout into the water each year. The program has been operating for several decades and supports the population in the lake.
