The lake partly fills a 2,148-foot-deep (655 m) caldera [3] that was formed around 7,700 (± 150) years ago [4] by the collapse of the volcano Mount Mazama. No rivers flow into or out of the lake; the evaporation is compensated for by rain and snowfall at a rate such that the total amount of water is replaced every 150 years. [ 5 ]
If magma continues to be injected into the collapsed magma chamber, the center of the caldera may be uplifted in the form of a resurgent dome such as is seen at the Valles Caldera, Lake Toba, the San Juan volcanic field, [7] Cerro Galán, [26] Yellowstone, [27] and many other calderas. [7]
