Green River (Colorado River tributary)
The Green River, located in the western United States, is the chief tributary of the Colorado River.
The watershed of the river, known as the Green River Basin, covers parts of Wyoming, Utah, and Colorado.
The Green River is long, beginning in the Wind River Mountains of Wyoming and flowing through Wyoming and Utah for most of its course, except for into western Colorado.
Much of the route is through the Colorado Plateau and through some of the most spectacular canyons in the United States.
It is only slightly smaller than the Colorado when the two rivers merge, but typically carries a larger load of silt.
The average yearly mean flow of the river at Green River, Utah is per second.
The status of the Green River as a tributary of the Colorado River came about for mainly political reasons.
In earlier nomenclature, the Colorado River began at its confluence with the Green River.
Above the confluence the Colorado was called the Grand River.
In 1921, Colorado U.S. Representative Edward T. Taylor petitioned the Congressional Committee on Interstate and Foreign Commerce to rename the Grand River as the Colorado River.
On July 25, 1921, the name change was made official in House Joint Resolution 460 of the 66th Congress, over the objections of representatives from Wyoming and Utah and the United States Geological Survey which noted that the drainage basin of the Green River was more extensive than that of the Grand River, although the Grand carried a higher volume of water at its confluence with the Green.
