Trillium Lake is located 7.5 miles south-southwest of Mount Hood and 1.5 miles east of Trillium Lake Basin Cabins. The lake itself was created by the Oregon Department of Fish and Wildlife in 1960 when a dam at the headwaters of Mud Creek was erected.
The area which is now the lake was part of the historic Barlow Road, a component of the Oregon Trail. Barlow Road at the time was a log road which extend across the marshes to the toll station at Summit Meadow (1866-1870). Barlow Cabin's east windows face Summit Meadow.
