List of longest streams of Oregon
![A wide placid river flows through the woods.](http://upload.wikimedia.org/wikipedia/commons/thumb/c/ce/Indian_Mary_2.jpg/300px-Indian_Mary_2.jpg)
Seventy-seven rivers and creeks of at least 50 miles (80 km) in total length are the longest streams of the U.S. state of Oregon. All of these streams originate in the United States except the longest, the Columbia, which begins in the Canadian province of British Columbia and flows 1,249 miles (2,010 km) to the sea near Astoria. The second-longest, the Snake River, which at 1,078 miles (1,735 km) is the only other stream of more than 1,000 miles (1,600 km) on the list, begins in Wyoming and flows through parts of Idaho and Washington, as well as Oregon. Some of the other streams also cross borders between Oregon and California, Nevada, Idaho, or Washington, but the majority flow entirely within Oregon.
The Atlas of Oregon ranks 31 rivers in the state by average streamflow; the top five are the Columbia, Snake, Willamette, Santiam, and Umpqua.[1] Not all Oregon rivers with high average flows are on this list of longest streams because neither their main stems nor any of their tributaries (including what are called "forks") are at least 50 miles (80 km) long. High-flow streams mentioned in the Atlas but not included in this long-stream list are the Metolius, Hood, Youngs, and Coos rivers. On the other hand, the list includes four low-flow intermittent streams—Dry River, Rattlesnake Creek, Rock Creek, and Dry Creek—that cross parts of the Oregon High Desert.
The direction of Oregon stream flow is influenced by four major drainage divides: the Oregon Coast Range on the west, the Cascade Range further inland, the Klamath–Siskiyou Mountains in the southwest, and the Blue Mountains in the northeast. One set of streams, including the Nehalem River, flows directly into the Pacific Ocean or into larger streams flowing directly to the Pacific; other streams, such as the Deschutes River, flow into the Columbia River or its tributaries. A third set, including the Klamath River and its tributaries, originates in Oregon, but its waters eventually flow into northern California before reaching the ocean. Other streams like the Donner und Blitzen River flow into closed basins, such as Malheur Lake, that have no outlet to the sea.[1]
Source data for the table below came from topographic maps created by the United States Geological Survey and published on-line by TopoQuest,[2] and from the Atlas of Oregon;[1] the Oregon Atlas and Gazetteer;[3] two federally produced geographic information system (GIS) datasets—the National Hydrography Dataset and the National Watershed Boundary Dataset—and other sources as noted. In the table, total lengths are given in miles (mi) and kilometers (km), and elevations are in feet (ft) and meters (m).

Notes and references
- Notes
- ^ Only 307 miles (494 km) of the Columbia River flow through Oregon.[8]
- ^ Only 235 miles (378 km) of the Snake River flow through Oregon.[12]
- ^ Only 198 miles (319 km) of the Owyhee River flow through Oregon.[14]
- ^ Only 46 miles (74 km) of the Klamath River flow through Oregon.[18]
- ^ Only about 144 miles (232 km) of the Grande Ronde River flow through Oregon. The river leaves Oregon and enters Washington at about river mile 39, reenters Oregon at river mile 38, and flows back into Washington at river mile 37. The distance within Oregon is the total length, 182 miles (293 km), minus the distance 38 miles (61 km) in Washington.[31]
- ^ Only 52 miles (84 km) of Jordan Creek flow through Oregon. The creek enters Oregon at about river mile 52.[11]
- ^ Only 39 miles (63 km) of Succor Creek flow through Oregon. The creek enters Oregon at about river mile 44 and leaves it at about river mile 5.[11]
- ^ Only about 46 miles (74 km) of the Lost River flow through Oregon. The river enters Oregon at about river mile 48 and leaves it at about river mile 2.[119]
- ^ About 50 miles (80 km) of the Applegate River flow through Oregon. This is the sum of the 46 miles (74 km) marked on topo maps plus the remaining distance to the California border, measured by map scale and ruler.[157]
- ^ Only 36 miles (58 km) of Cow Creek flow through Oregon. The creek enters Oregon at about river mile 36.[11]
- ^ Only about 10 miles (16 km) of the Walla Walla River flow through Oregon. The river leaves the state and enters Washington at about river mile 40.[171]
