The Payette River is a river in southwestern Idaho, and is a major tributary of the Snake River. Its headwaters originate in the Sawtooth and Salmon River mountains at elevations over 10,000 feet (3,000 m). The drainage flows in a southwesterly direction for over 175 miles (280 km) where it empties into the Snake River near the city of Payette at an elevation of 2125 feet (648 m). The Payette River Basin comprises about 3240 square miles (8390 km²).
François Payette The river is named for François Payette (1793-18xx), a French-Canadian fur trapper and one of the first white settlers in the area. Payette ventured east from Astoria, Oregon in 1818 and later headed the old Fort Boise trading post near Parma for the British Hudson's Bay Company from 1835-1844. A large and amiable man, he was highly regarded for his helpful assistance to the many travelers who came through the fort. After his retirement in 1844, Mr. Payette returned to Montreal, but the rest of his life is a mystery. Tributaries Principal tributaries are the North and South Forks of the Payette River. The North Fork drains about 950 square miles (2460 km²), beginning north of McCall, and the South Fork about 1200 square miles (3100 km²), starting on the west side of the Sawtooths beneath the 10,211 feet (3112 m) Mount Payette, flowing past Grandjean, and down to Lowman. The shorter Middle Fork parallels the lower North Fork ten miles to the east, flowing south through Crouch and into the South Fork. Further east, the Deadwood River parallels the Middle Fork and runs into the South Fork just west of Lowman. The North and South Forks merge at Banks at an elevation of 2790 feet (850 m). This junction is the beginning of the main Payette River, which flows 15 miles south to Horseshoe Bend, then west into Black Canyon Reservoir. Below the dam, the river flows past Emmett and Payette, then empties into the Snake River at the Oregon border. The Payette River has an average annual discharge into the Snake River of 2,192,000 acre-feet (2.7 km³) of water. Fish & Reservoirs Due to the wide range in elevation, the Payette River has a variety of fish and fish habitats. Salmon and steelhead were eliminated in the drainage by Black Canyon Dam. From its mouth upstream to Black Canyon Dam, the river supports a mixed fishery for coldwater and warmwater species. Mountain whitefish make up the bulk of game fish in this section of river, with smallmouth bass, largemouth bass, channel catfish, black crappie, rainbow trout, and brown trout making significant contributions. Upstream from Black Canyon Dam, the gradient of the river increases with coldwater species increasing in abundance. The South Fork of the Payette River supports excellent populations of wild rainbow trout. The North Fork of the Payette River has been severely altered by railroad and highway construction and provides only a marginal fishery for salmonids. However, in unaltered sections such as the Cabarton reach, the North Fork is very productive for salmonids. There are five major impoundments in the Payette basin: Black Canyon, Sage Hen, Paddock, Cascade, and Deadwood reservoirs. There are also several small impoundments and natural lakes with increased storage, such as the three Payette Lakes. Black Canyon, on the mainstem, provides only marginal fish habitat. Sand from upstream land disturbances has covered most of the habitat. Paddock Reservoir, on Big Willow Creek, has one of the better populations of black crappie in the state and a good fishery for largemouth bass. Cascade Reservoir on the North Fork is one of the most heavily fished waters in the state. Cascade has an abundance of yellow perch, coho salmon, and rainbow trout. Deadwood Reservoir contains kokanee and cutthroat trout. Alpine lakes within the Payette River drainage are stocked with rainbow trout, cutthroat trout, rainbow x cutthroat hybrids, golden trout, and arctic grayling. Brook trout are also present in a number of lakes. Whitewater The Payette River is famous for its whitewater. Kayaking on the lower North Fork just above Banks is world-class, easily viewed from Highway To the east, the South Fork's Canyon, west of Lowman, is a challenging Class IV run for rafting. Along this trip is a 40 foot (13 m) Class VI waterfall (Big Falls), which is portaged. The North and South Forks merge at Banks to form the (main) Payette River, providing a float trip with numerous Class III rapids. The highway is on the east bank and a scenic railroad is on the west side of the river. | ||||||||
