UC Davis Natural Reserve System - Eagle Lake
Located in the remote northeastern corner of California at the juncture of four major geologic provinces: the Sierra Nevada, Cascades, Great Basin, and volcanic Modoc Plateau, the Eagle Lake Biological Field Station affords excellent opportunities to study California's fourth largest lake. A Pleistocene remnant of immense Lake Lahonton, Eagle Lake covers 12,146 hectares and stretches for nearly 23 kilometers. Eagle Lake supports only five fish species, all native and thriving: tui chub, Tahoe sucker, speckled dace, Lahontan redside and rainbow trout. Surrounding landscape is primarily volcanic with basaltic flows, lava caves, and a nearby caldera. Diverse habitats on lava flats accessible from the field station include fir and pine forests, mixed conifers, juniper and sagebrush scrub, and mountain mahogany.
