Green River

Green River.

1 River, 370 mi (595 km) long, rising in central Ky. and flowing generally NW, through Mammoth Cave National Park, to the Ohio River near Evansville, Ind. Locks and dams make the Green River navigable upstream to the park.

2 River, 730 mi (1,175 km) long, rising near the Continental Divide, W Wyo., and flowing generally S through W Wyo., NW Colo., and E Utah to the Colorado River in Canyonlands National Park, SE Utah; it is the largest tributary of the Colorado. Most of its course flows through deep canyons, including Canyon of the Lodore in Dinosaur National Monument (see National Parks and Monuments, table). The White, Yampa, and San Rafael rivers are its main tributaries. The Colorado River storage project of the U.S. Bureau of Reclamation has extensively developed the Green River basin for irrigation, mining, and hydroelectric power; Flaming Gorge Dam, NE Utah, is the major unit in this project.

Green River

River, western U.S. It flows from western Wyoming south into Utah, where it turns east to make a loop through the northwestern corner of Colorado. Turning south in Utah, it enters the Colorado River in Canyonlands National Park after a course of 730 mi (1,175 km). Originally known as the Spanish River, it was renamed in 1824, probably for its colour, derived in places from green soapstone banks along its course.

Green River 

the name of two rivers in the USA.

(1) In Kentucky, a left tributary of the Ohio River (Mississippi Basin). Length, 449 km; area of basin, 24,400 sq km. The source of the Green River is in the western part of the Appalachian plateau. It flows mainly through flat country and meanders greatly. The rate of discharge varies sharply from 4–5 cu m per sec to 3.000–6,000 cu m per sec (during the heavy summer rains). The channel has locks and is navigable for river vessels up to 320 km from its mouth. Mammoth Cave is located in the valley in the middle reaches of the river, near the town of Mammoth Cave.

(2) In Wyoming and Utah, a right tributary of the Colorado River. Length, 1,180 km; area of basin, 116,500 sq km. The source of the Green River is in the western part of the Wind River Range. Most of the river flows through steep mountain gorges, but in places the valley widens. Highwater is in the spring and summer. The average rate of discharge in the lower reaches near the city of Green River is about 200 cu m per sec. The greatest rate of discharge is about 2,000 and the least about 10 cu m per sec. A hydroelectric power plant and reservoirs are located on the Green River. (The largest reservoir is Strawberry.)
