The Price River is a southeastward flowing river in Carbon, Utah and Emery counties in eastern Utah. It is a tributary to the Green River, itself a tributary to the Colorado River. History The river's early name was the White River, but it was changed in the summer of 1869 when LDS Bishop William Price of Goshen, Utah, explored the region and renamed it, making the White River above Colton into a tributary of the Price River. The town of Price was later named after the river. Watershed and course The Price River watershed comprises . The USGS indicates that the Price River originates at Scofield Reservoir in the Wasatch Plateau in Carbon County in central Utah. From the reservoir, the river flows briefly eastward and northeastward into Utah County, where it receives the flows of the White River at Colton. Colton was originally named Pleasant Valley Junction, and Scofield Reservoir would occupy a large portion of Pleasant Valley. Alternatively, historical accounts place the origin of the Price River at the confluence of the White River and Fish Creek, such that lower Fish Creek continued from below Scofield Dam to said confluence. The White River drains the Tavaputs Plateau. From Colton the Price River continues southeastward, receiving Beaver Creek from the right and then Kyune Creek from the left (at Kyune). Below Kyune, the river enters Price Canyon and drops back into Carbon County alongside U.S. Route 6. The canyon of the Price River is a physiographic break between the Wasatch Plateau and the Book Cliffs. Next, from the left the Price River receives Willow Creek at Castle Gate. Willow Creek is the largest tributary in the Book Cliffs area with a watershed of . After leaving Price Canyon at Heiner, the Price River enters the city of Helper, and then Price. From Price, the river continues southeast along the northeastern edge of the San Rafael Swell to the ghost town of Woodside, at which point it proceeds east into canyonlands, joining the Green River in Gray Canyon, about north of Green River, Utah. The Scofield Reservoir was formed by the construction of the Scofield Dam in 1946. Scofield Reservoir is fed by Pondtown Creek, Mud Creek, and Fish Creek, the primary tributary to the reservoir. There are plans to build a second dam on the river, upstream from the Scofield Reservoir, called the Gooseberry Narrows Dam near the confluence
