The United States Congress designated the Lower White River Wilderness (map
) in 2009 and it now has a total of 2,871 acres
All of this wilderness is located in Oregon
and is managed by the Bureau of Land Management and the Forest Service.
The White River rises in the high Cascades in western Wasco County, in the Mount Hood National Forest on the southeast flank of Mount Hood. The headwaters are just below White River Glacier in White River Canyon. Additions to the Mount Hood Wilderness protect upper portions of the river, while the Lower White River Wilderness, southeast of the Mount Hood Wilderness and east of highway 26, protects a segment of lower river stretch.
