Geomorphology and River Hydraulics of the Teton River Upstream of Teton Dam

Teton River, Idaho, May 2000

Read an overview in the Teton River page in the Project Gallery.

The construction and subsequent failure of Teton Dam in 1976 changed the physical and biological characteristics of the Teton River Canyon for 17 miles upstream of the dam site. This report documents the existing physical conditions and the changes that have occurred to the geomorphology and river hydraulics in the Teton River canyon as a result of the reservoir inundation and subsequent failure of Teton Dam.
