The Salmon River is located in Idaho in the northwestern United States. The Salmon is also known as The River of No Return. It flows for 425 miles (684 km) through central Idaho, draining 14,000 square miles (36,260 km2) and dropping more than 7,000 feet (2,134 m) between its headwaters, near Galena Summit above the Sawtooth Valley in the Sawtooth National Recreation Area, and its confluence with the Snake River. Its discharge is 11,060 cubic feet (313 m3) per second.. Cities located along the Salmon River include Stanley, Clayton, Challis, Salmon, Riggins, and White Bird. Redfish Lake and Little Redfish Lake near Stanley flow into the river via Redfish Lake Creek.
The headwaters of the Salmon River are in the mountains of central and eastern Idaho (Lemhi Range, Sawtooth, Salmon River Mountains, Clearwater and Bitterroot Range). The main fork of the Salmon is joined by the Yankee Fork, East Fork, Pahsimeroi, Lemhi, North Fork, Middle Fork, South Fork, and Little Salmon Rivers before emptying into the Snake River on the Oregon-Idaho border, north of Hells Canyon, 15 miles (24 km) south of Washington and 40 miles (64 km) south of Lewiston. The Middle Fork of the Salmon River is one of the premier recreational rafting and kayaking rivers in the world.
Ten miles (16 km) downstream (west) of its confluence with the Middle Fork, the Salmon River becomes the dividing line for the two time zones in Idaho: Mountain time to the south, Pacific time to the north, bisecting the state at approximately 45.5 degrees north latitude.
The Salmon River area has been home to people for at least the last 8,000 years. Much of the area was inhabited by several tribes, including the Nez Perce. The river was a rich source of food for the indigenous people of the area, who relied on the abundant salmon species and other wildlife.
Corps of Discovery
"...I shall in justice to Capt. Lewis who was the first white man ever on this fork of the Columbia Call this Louis's river. ...The Westerly fork of the Columbia River [the present Salmon River] is double the size of the Easterley fork [the present Lemhi River] & below those forks the river is ...100 yards [100 m] wide, it is very rapid & Sholey water Clear but little timber."
The honor didn't last long; by 1810 maps of the area were already referring to "Louis' River" as the Salmon. Clark had thought that the Salmon River was the Snake River, thus he called it the "Westerly fork of the Columbia". The Snake River retained the variant name "Lewis River" or "Lewis Fork" longer than did the Salmon.
In the 1860s, placer deposits of gold were found along the river, and a gold rush began. Miners came to the area, causing clashes with the Nez Perce on their ancestral tribal lands. Many historic and present day mines (including dredging operations) can be seen while traveling along the river.
Several national forests and Sawtooth National Recreation Area provide for numerous recreation opportunities within the river's watershed. Two segments (the Middle Fork and a section of the main Salmon River) are protected as National Wild and Scenic Rivers. Today, the Salmon is a popular destination for whitewater kayaking, canoeing or rafting. Both the Middle Fork and Main Fork travels through the Frank Church-River of No Return Wilderness Area. The Middle Fork is about 110 miles long, while the Main Fork is about 81 miles long. The Middle Fork raft trip run ends 7 miles prior to the beginning of the Main Fork run; Corn Creek is the start of the Main Fork section of the Salmon River. The South Fork flows through Payette National Forest and enters the Main Fork rafting/fishing section at Mackay Bar. The Main Fork raft trip ends about 25 miles east of the city of Riggins, Idaho, either at Vinegar Creek or Carey Creek. Thus marking the beginning of the Lower Salmon rafting trips. Single and multiple day trips on the river are available and offer beautiful views of wildlife and scenery. The river canyon allows for magnificent views of the complex geology of the region. The Middle Fork of the Salmon River is known as one of the best catch and release fly fisheries in the nation. While traveling through the Frank Church-River of No Return Wilderness Area, you enter the second deepest canyon in the continental U.S. Deeper than the Grand Canyon. It is roughly at 7,000 feet in depth.
The Salmon River historically produced 45% percent of all the steelhead (salmon) and 45 percent of all the spring and summer chinook salmon in the entire Columbia River Basin. The Salmon River basin contains most (up to 70 percent) of the remaining salmon and steelhead habitat in the Columbia River Basin. Despite the abundant salmon habitat in the river, these fish have been declining, in large part because of the effects of four federal reservoirs and dams on the lower Snake and Columbia rivers.
The United States Geological Survey operates four stream gauge water level monitoring stations on the main stem of the Salmon River and 17 others on its tributaries. Real time data is available for each station on the USGS website. For a map of these see Salmon River USGS Station Map or in the box at right.
