Green River

From its birthplace high up in the Wind River Range to where it joins the mighty Colorado River near Lake Powell, the Green River flows for 764 miles from glacier-clad peaks, through pine forests, sagebrush plains, and fiery desert canyons. It is the largest tributary to the Colorado River.

The Upper Green River, which flows from north to south across western Wyoming, is renowned for its blue ribbon rainbow and brown trout fishery. A 1999 study conducted by the Wyoming Game and Fish Department found the fishery from the river’s source down to Flaming Gorge Reservoir along the Utah border was worth $5 million to the local economy. The Upper Green River Valley is also treasured by hunters and wildlife enthusiasts for its Serengeti-like wildlife herds. The sagebrush plains between the Wyoming and Wind River mountain ranges provide critical winter range for an estimated 100,000 elk, mule deer, and pronghorn antelope, as well as sage grouse. The pronghorn antelope migration from Grand Teton National Park south to their wintering grounds in the Red Desert is believed to be the longest big game migration route in the lower 48 states.

Over the past decade the Upper Green River Valley has become ground zero for one of the biggest oil and gas booms in the United States. GYC and its conservation allies have joined to form the Upper Green River Valley Coalition to minimize the adverse effects of energy development on wildlife, air quality and water quality.
