Lava Lake lies in the Cascade Range west-southwest of Bend in the U.S. state of Oregon. It is a close neighbor of Little Lava Lake, from which it is separated by solidified lava. Lava Lake is at an elevation of 1,440 m in the Deschutes National Forest. The lake covers 149 ha to an average depth of 6.1 m.
Lava Lake, Little Lava Lake, and other nearby lakes are volcanogenic, having formed after lava flows from Mount Bachelor altered drainage patterns in the area. Solidified lava flows are visible along the shorelines of both lakes, and the volcanic peaks Broken Top and South Sister can be seen to the north.
Fish in the lake include rainbow trout that grow to 61 cm and brook trout that sometimes reach 48 cm. Controlled populations of tui chub also live in the lake.
