The Nelson Creek segment of the Whitewater River in Oregon is a popular destination for kayaking and rafting. The ideal streamflow range for this section is between 400-800 cfs, as water levels below 400 cfs may be too low to navigate and levels above 800 cfs may be too dangerous. The segment covers approximately 6 miles and is rated as a Class III-IV difficulty level, with several challenging rapids such as "Toilet Bowl" and "Pinball."

As with all whitewater runs, safety is a top priority. Kayakers and rafters should wear helmets and personal flotation devices at all times and be familiar with rescue techniques. The Nelson Creek segment is also subject to specific regulations, including a permit requirement for all commercial outfitters. Additionally, the use of motorized watercraft is not permitted on this section of the river.

Overall, the Nelson Creek segment of the Whitewater River provides a thrilling and challenging experience for experienced kayakers and rafters. It is important to consider water levels and safety regulations before embarking on any whitewater adventure.
