Trillium Lake, Reservoir in Mount Hood National Forest, Oregon.
The 63-acre lake mirrors Mount Hood on its surface and features a 2-mile trail loop surrounding the water body at 3,600 feet elevation.
The Department of Fish and Wildlife created this reservoir in 1960 by constructing a dam at Mud Creek's headwaters, a tributary of the Salmon River.
The location previously served as part of the Barlow Road, where a log pathway across marshes led travelers to Summit Meadow's toll station.
The reservoir includes 57 camping sites with tables, fire rings, drinking water access, and a seasonal boat ramp for water activities.
During winter months, the lake transforms into a Nordic skiing destination with access through a dedicated trailhead across from Snow Bunny lodge.
