The Whitehorse River Run in Nevada is a 14-mile stretch of Class III to IV rapids, with an ideal streamflow range of 600-3000 cfs. The run begins at Whitehorse Creek and ends at the Jacks Valley Road Bridge. This section of the river includes several notable rapids, including "The Narrows," "Pinball," and "Nemesis," which are known for their technical challenges and high-intensity whitewater.

In terms of specific regulations, the river is managed by the Bureau of Land Management and requires a permit for commercial outfitters. The area is also subject to seasonal closures and restrictions based on weather and water conditions, so it is important to check with local authorities before planning a trip. It is also recommended that all paddlers wear appropriate safety gear, including helmets and personal flotation devices.
