The Deschutes River /dəˈʃuːts/ in central Oregon is a major tributary of the Columbia River. The river provides much of the drainage on the eastern side of the Cascade Range in Oregon, gathering many of the tributaries that descend from the drier, eastern flank of the mountains. The Deschutes provided an important route to and from the Columbia for Native Americans for thousands of years, and then in the 19th century for pioneers on the Oregon Trail. The river flows mostly through rugged and arid country, and its valley provides a cultural heart for central Oregon. Today the river supplies water for irrigation and is popular in the summer for whitewater rafting and fishing.

The river flows generally north, as do several other large Oregon tributaries of the Columbia River, including the Willamette and John Day.

Course

The headwaters of the Deschutes River are at Little Lava Lake, a natural lake in the Cascade Range approximately 26 miles (42 km) northwest of the city of La Pine. The river flows south into Crane Prairie Reservoir, then into Wickiup Reservoir, from where it heads in a northeasterly direction past the resort community of Sunriver and into the city of Bend, about 170 miles (270 km) from the river mouth.[7]

In central Bend, the river enters Mirror Pond, an impoundment behind Newport hydroelectric dam. The pond extends upstream to the Galveston Bridge and is a feature of Drake Park as well as Harmon, Pageant, and Brooks parks.[8] From April through October, diversions to Central Oregon Irrigation District canals reduce the river flow between Bend and Pelton Reregulating Dam, at river mile (RM) 100; that is, river kilometer (RK) 160).[9]

The river continues north from Bend, and just west of Redmond, Oregon. Here it passes by Eagle Crest Resort and Cline Falls State Scenic Viewpoint. As it heads north through the central Oregon high desert, the river carves a gorge bordered by large basalt cliffs. By the time it reaches Lake Billy Chinook, a reservoir west of Madras, the river is approximately 300 feet (91 m) below the surrounding plateau, the Little Agency Plains and Agency Plains. At Lake Billy Chinook the river is joined by the Crooked and Metolius rivers.

Beyond the dam, the river continues north in a gorge well below the surrounding countryside. It passes through the Warm Springs Indian Reservation, which includes the city of Warm Springs and the Kah-Nee-Ta resort. The river ends at its confluence with the Columbia River, 5 miles (8 km) southwest of Biggs Junction and 204 miles (328 km) from the Columbia's mouth on the Pacific Ocean.[7]

Tributaries

Named tributaries of the Deschutes River from source to mouth include Snow Creek then the Cultus River, Cultus Creek and Deer Creek, which enter at Crane Prairie Reservoir. Further downstream come the Fall River, the Little Deschutes River, and the Spring River followed by Tumalo Creek and Whychus Creek.[7]

The Metolius River and the Crooked River are next, both entering at Lake Billy Chinook. Then come Seekseequa Creek and Willow Creek followed by Dry Hollow and Campbell, Shitike and Trout creeks, after which comes the Warm Springs River. Further downstream are Swamp, Skookum, Oak, Antoken, Cove, Eagle, Nena, Wapinitia and Bakeoven creeks. Spring Creek is next, followed by Oak Springs Creek and the White River. Below that are Winterwater and Elder creeks.[7]

History

Prior to 80,000 years ago, the river ran along the east side of Pilot Butte and a lava flow from Lava Top Butte filled in this ancient channel.[10] Previously, the basalt of the Bend lava flow, associated with the Lava River Cave, had diverted the river westward to its present-day location.[11][12]

The river was named Riviere des Chutes or Riviere aux Chutes, French for River of the Falls, during the period of fur trading.[1] The waterfall it referred to was the Celilo Falls on the Columbia River, near where the Deschutes flowed into it. (These falls no longer exist, having been inundated by the lake behind The Dalles Dam).

Lewis and Clark encountered the river on October 22, 1805, and referred to it by the Native American name Towarnehiooks; on their return journey they gave it the new name Clarks River.[1] Variant names include Clarks River, River of the Falls, Riviere des Chutes, Chutes River, and Falls River.[3]

During the middle 19th century, the river was a major obstacle for immigrants on the Oregon Trail. The major crossing point on the river was near its mouth in present-day Deschutes River State Recreation Area. Many immigrants camped on the bluff on the west side of the river after making the crossing. The remains of the trail leading up to the top of the bluff are still visible.[13]

In 1910, Mirror Pond was created by the construction of the Bend Water, Light & Power Company dam on the river in Bend. The dam provided the city with its initial source of electricity. The dam has been owned by Pacific Power since 1930 and still produces electricity that supplies approximately 400 Bend households.[14]

In 1908, two competing railroad companies, the Deschutes Railroad and the Oregon Trunk Railway, raced to build a line from the mouth of the river to Bend. The Deschutes Railroad, a Union Pacific subsidiary, was owned by Edward H. Harriman and the Oregon Trunk was owned by James J. Hill.[15][16]

In 1964, on the Deschutes River, Portland General Electric (PGE) built the largest hydroelectric dam in Oregon. This dam, named Round Butte Dam, stands 440 feet (130 m) above Lake Simtustus, a 611-acre (247 ha) reservoir impounded by Pelton Dam.[17]

Fishing

The river is world-renowned for its fly fishing. It is home to Columbia River redband trout (Oncorhynchus mykiss gairdneri) known locally as "redsides". The redsides grow larger than most and also have a distinct darker red stripe than most wild rainbow trout.[18] They are abundant in this stretch of the river, which has counts of 1,700 fish of 7 inches in size per mile (1,100 fish of 18 centimeters in size per kilometer) above Sherars Falls, and they are noticeably stronger than trout who do not have to cope with life in such a big, powerful river. The average catch for these fish is 8 to 15 inches (20 to 38 cm), and some are much larger. These redside or redband trout are found throughout the river. Fishing for them is most popular from Warm Springs down to Macks Canyon. (Warm Springs Reservation owns the entire Deschutes West Bank from 16 miles (26 km) south of Maupin to Lake Billy Chinook and on up to Jefferson Creek on the Metolius River arm) below Pelton Dam.[19] Fishing from Tribal lands requires special permits. From Pelton Dam to the mouth the Deschutes is one of America's most productive trout waters and a top producer of summer steelhead, managed primarily for wild trout. This 100-mile (160 km) stretch of river drops 1,233 feet (376 m), carving a volcanic rock canyon 700 to 2,200 feet (213 to 671 m) deep.

Fly fishermen come from around the world in the last two weeks in May through the first two weeks in June to take advantage of the hatching stoneflies, both salmonflies and golden stoneflies (Hesperoperla pacifica). These insects are in the river year-round; however their large adults are a major food source for the fish: artificial weighted stonefly nymph patterned tied flies are a staple for Deschutes anglers year round.

Sport fishing for Steelhead occurs in the river from the mouth to Round Butte Dam. Sport fishing for spring and fall chinook salmon occurs from the mouth to Sherars Falls. Tribal fishing for chinook and steelhead occurs at Sherars Falls.

In Lake Billy Chinook, there are fisheries for kokanee, bull trout, rainbow trout, brown trout, and several warm-water species such as large mouth bass and a very large population of small mouth bass. There are also periodic commercial fisheries for crayfish. The bull trout that are caught in this reservoir are some of the largest bull trout caught on the west coast. The numbers are scarce because the bulls are threatened; however, numbers have risen every year since they became protected. The lake allows an individual to keep a bull trout that measures more than 24 inches (61 cm). (This is included for a daily bag limit.)[20]

River use

Much of the flow of the upper Deschutes River is diverted into canals to irrigate farmland; irrigation districts take nearly 98% of the river's flow in the summer months.[21] The growth of cities like Bend and Redmond also increased demand on the river's water, which is over-allocated. Because the existing canals lose about half of their water due to seepage,[22] there is pressure to convert these canals into pipelines, a move that is resisted by many locals for historic and aesthetic reasons.[23] Golf courses have also been an issue with water allocation. There are 13 golf courses throughout Bend, Redmond, and Sunriver.

There are primarily two sections of the river popular for whitewater rafting and kayaking. The upstream section known as the Big Eddy is a short segment upriver from the city of Bend between Dillon and Lava Island falls. The lower and more heavily used section is from the town of Warm Springs downstream to just above Sherars Falls. The densest use is from RM 56—about 4 miles (6.4 km) above Maupin—to RM 44, just above Sherars Falls.
