| Description |
The White River lies east of the Cascade Range and south of the Columbia River Gorge. Originating on Mt. Hood, the river flows for approximately 53 miles to its confluence with the Deschutes River just above Sherar's Bridge. The river’s outstandingly remarkable values include geology, hydrology, botany, fish habitat and populations, wildlife habitat and populations, cultural resources, recreation and scenery. All but 0.6 miles of the river at White River Falls is designated as a wild and scenic river. The USDA Forest Service manages the upper three segments, A-C, and the Bureau of Land Management manages the lower three, D-F. Segments C and D flow through a steep V-shaped canyon. The canyon walls, a series of steps formed by benches and rock walls, consist of alternating layers of fluvial sediments, ash flows and lava flows. The climate in these two segments continues to become dryer. Precipitation ranges from 50 inches at the beginning of Segment C to 30 inches at the lower end of Segment D. Segment C contains Keeps Mill and Flume, an early development for water and timber. Segment D contains an historic waterwheel and other historic structures. Segments E and F contain the oldest rocks in the White River. The 14.5-million-year-old French Springs Member of the Wanapum Basalt lies over the 15-million-year-old Grande Ronde Basalts. The climate is hot and dry with as little as 10 inches of annual precipitation at the river mouth. Vegetation consists mostly of shrubs, forbs and grasses. Viewpoints from Highways 197 and 216 offer a scenic contrast between the riparian vegetation and the desert steppe. Photo by Greg Shine, BLM Info via Rivers.gov |
