Price өзені: тарихы, географиясы және қорғау мәселелері

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.

The Price River watershed comprises 1900 square miles (4,921 km2). 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. 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 81 square miles (210 km2). 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 of Gooseberry Creek with Fish Creek. The proposal has met with opposition out of concern for environmental impacts on trout fisheries in the Price River headwaters and the planned diversion of the water impounded by the dam out of the Colorado River basin to supplement the irrigation systems of the Sanpete Valley. As a result of the planned dam the Price River was included on the American Rivers list of the top ten endangered rivers in the United States in 2005. Just downstream of the town of Price, a partnership of the Carbon Canal Company (CCC), The Nature Conservancy (TNC), and the Utah Division of Wildlife Resources (UDWR), is expanding the Olsen Reservoir so that it can capture high spring Price River flows at the end of the Carbon Canal and store it, for agricultural use and to recharge the river in dry seasons and drought years. Tributaries downstream of Price are largely ephemeral. The largest is Grassy Trail Creek which exits the Book Cliffs at East Carbon, Carbon County, and joins the Price River south of Cedar, Emery County.

The headwaters of the Price River harbor Colorado River cutthroat trout ((Oncorhynchus clarki pleuriticus). Distribution and abundance of this cutthroat trout subspecies are now limited to small populations in less than 1% of its historic range in the upper tributaries of the Colorado River watershed. The chief vulnerability of Colorado River cutthroat trout is hybridization with non native rainbow trout and competitive replacement by non native brown trout (Salmo trutta) and brook trout (Salvelinus fontinalis). The federally endangered Colorado pikeminnow (Ptychocheilus lucius) is extant in the lower of the Price River.

The Price is a small, shallow river and is normally unnavigable. However, during high springtime flows, the 23.5 mile (38 km) below the Scofield Dam to Castle Gate contain Class I to V whitewater. The river has become increasingly popular with canoeists and kayakers. The tailwater below Scofield Reservoir is sometimes called Lower Fish Creek (although the USGS sets the source of the Price River at the reservoir dam). It is considered Blue Ribbon flyfishing for large brown trout. This uppermost reach is paralleled by railroad tracks in a very scenic canyon and is stocked annually with non native brown trout fingerlings, which have been known to mature up to .
