where does the desplaines river start and end
Des Plaines River The Des Plaines River (/dɪsˈpleɪnz/) is a river that flows southward for 133 miles (214 km)[1] through southern Wisconsin and northern Illinois[2] in the United States Midwest, eventually meeting the Kankakee River west of Channahon to form the Illinois River, a tributary of the Mississippi River.
Snake River At the halfway point in Hells Canyon, in one of the most remote and inaccessible sections of its course, the Snake River is joined from the east by its largest tributary, the Salmon River. From there, the Snake begins to form the Washington–Idaho border, receiving the Grande Ronde River from the west before receiving the Clearwater River from the east at Lewiston, which marks the head of navigation on the Snake. The river leaves Hells Canyon and turns west, winding through the Palouse Hills of eastern Washington. The Lower Snake River Project's four dams and navigation locks have transformed this part of the Snake River into a series of reservoirs. The confluence of the Snake and Columbia rivers at Burbank, Washington is part of Lake Wallula, the reservoir of McNary Dam. The Columbia River flows about 325 miles (523 km) further west to the Pacific Ocean near Astoria, Oregon.[10][13][14]
