ECOSYSTEMS > INLAND OREGON > LAKES AND PONDS
Some of the state’s lakes formed in the calderas of extinct or dormant volcanoes. As the volcanoes erupt, their mountain structure often collapses into a basin which, over time, fills with rainwater and creates these lakes.
In Oregon, the best known of these is the aptly-named Crater Lake, a 1,932-foot (588.8 m) deep basin located in the caldera of ancient Mt. Mazama. Additional caldera lakes include East Lake, Paulina Lake, Blue Lake and the North and South Twin Lakes.
See the maps below for directions to these locations.
