SELWAY RIVER (4 Rivers), ID
The Selway River flowing for 47 miles through the heart of the Selway-Bitterroot Wilderness was the only river in the U.S. that received instant inclusion to both the Wilderness Preservation System and the Wild and Scenic River System as a "wild river".
A unique characteristic of the Selway River is that over a very short distance the river substantially increases in flow volume with each major tributary, dropping an average of 28 feet per mile, creating a technical whitewater experience to challenge even expert boaters. Immediately below the confluence with Moose Creek, the increased gradient of 50 feet per mile combined with a major increased volume of flow creates an extremely demanding technical section of the river. Numerous exposed and barely submerged rocks, and stretches of unbroken whitewater with few quiet recovery pools, require a high level of skill and expertise.
