Donner und Blitzen River

Donner und Blitzen River

From its headwaters to the Malheur National Wildlife Refuge boundary, the Donner und Blitzen River is located in the eastern Oregon high desert. Although much of its course is through marsh, it offers scenic glaciated canyons and unique ecosystems. There is an exceptional wild trout fishery. Named by soldiers of German origin, the Donner und Blitzen River translates as "thunder and lightning" for a thunderstorm the soldiers experienced as they crossed the river.

The Donner und Blitzen River system also includes several spring-fed tributaries—South Fork Blitzen River, Little Blitzen River, Big Indian Creek, Little Indian Creek, Fish Creek, Mud Creek, and Ankle Creek—totaling 87.5 miles (140.8 km) of designated river.


Outstandingly Remarkable Values

Cultural (Historic Sites)

Historic sites and resources on Steens Mountain, including the river corridor, reflect the turn-of-the-century period of settlement, homesteading and livestock raising.

Located on the Little Blitzen River is the Riddle Brothers Ranch National Historic District, part of the historic context of pioneer settlement and the development of the livestock industry in the American West. Migrating from western Oregon, three bachelor brothers settled there in the early 1900s and built their ranch by gaining control of water in the area. They sold the ranch in the 1950s, and in 1986 the BLM purchased the property to manage the ranch for its historic value.

Fisheries

The Blitzen River supports a wild, native redband trout population and the Malheur mottled sculpin, both listed as sensitive species. It is recognized by anglers as one of Oregon's finest wild trout streams. Fish species in the Blitzen River above Page Springs Dam are redband trout, mountain whitefish, longnose dace and mottled sculpin. The redband trout is the species most commonly found in the system, indicating the presence of good stream habitat, water quality and quantity.

Geologic

Surface rock is predominantly Steens Basalt—thin, multiple flows of basalt approximately 15 million years old and several thousand feet in thickness. Thin patches of rhyolite ash-flow tuffs occur sporadically.

The area provides textbook examples of a U-shaped glaciated canyon. Steens Mountain is the northern-most uplifted fault block in the state of Oregon, with well-defined escarpments and graben valleys. It is unique in the region because its upper 2,000 feet were shaped during the ice age as glaciers formed in the creek and streambeds, and the intense weight of the snowcap caused depressions on the surface of the mountains. Over 2,500 was carved and gouged down to a layer of very hard basalt. A second glacial advance in the upper sections of the gorges and scarp created smaller hanging valleys in the tallest areas of the existing gorges.

Pre-Historic

The river corridor was used by Native Americans, including the Northern Paiute and their predecessors. The area was used for hunting, fishing and gathering plants for food. Prehistoric sites are known to be present in portions of the river system, and conditions for prehistoric site potential exist throughout the corridor.

Recreational

Steens Mountain is a destination for two- to four-day backpacking or horsepack experiences. Exceptionally high-quality recreation also includes fishing, and one section is designated catch-and-release in one section to protect the population of native fish. Other popular activities are hunting and the viewing and photography of wildlife and scenery.

Scenic

The river and its tributaries pass through several vegetation zones which are the result of temperature, elevation and precipitation. The lower area features sagebrush and bunchgrass, and the upper subalpine zone offers glaciated canyons and deep basalt formations whose viewsheds are largely untouched and in their natural condition.

Vegetation

The Blitzen and its tributaries host a great variety of plant communities and a large number of sensitive species. Riparian zones are dominated by willows, western birch, mountain alder, black cottonwood and quaking aspen, as well as other species. Sedge and grass-dominated meadows, bog areas, seeps wetland communities, subalpine and alpine communities are found in the system. The uplands include areas dominated by big sagebrush, western juniper, mountain mahogany, quaking aspen and mountain snowberry, and understory species include Idaho fescue, bluebunch wheatgrass and needlegrasses.

Wildlife

The Blitzen River drainage is highly valued for its abundant wildlife. The river area and adjacent uplands are used by an estimated 250 wildlife species. Mule deer winter in the lower four miles of the Blitzen River and the lower four miles of Fish Creek and summer in upper areas. Rocky Mountain elk and pronghorn antelope are also present.

Raptors, such as the American kestrels, and great horned owls nest along canyon rims of the Blitzen River and its tributaries, and the cliffs are also home to nesting turkey vultures and ravens. Sage grouse stay in the upper, flatter terrain, and chukars and valley quail are found along the river.
