The Resource

Yellowstone cutthroat trout are the native gems of the Greater Yellowstone aquatic ecosystem. Historically, they have flourished in southeastern Idaho’s Teton River, making spawning runs up into the mountain tributaries of the Teton Range.

Teton Creek Restoration ProjectThe Problem

Teton Creek, a valuable Yellowstone cutthroat trout spawning tributary, has seen precipitous declines in the Yellowstone cutthroat population. Between 1999 and 2003, their numbers declined by 95%, while non-native species increased by 300%. Numerous stressors have contributed to the diminishing populations of this “species of greatest concern” for the Snake River region. Teton Creek has been heavily degraded by illegal in-stream dredging and channelization by developers, stream dewatering for agricultural use, and destruction of riparian vegetation. More than one mile of Teton Creek has been completely altered from its natural state, with high velocities, no holding water, and no spawning grounds. This unstable stream section threatens the viability of one of the last remaining fluvial populations of Yellowstone cutthroat trout in the Teton basin.

Partnering for a Solution

The Teton Creek Restoration Project is a collaborative effort with Friends of the Teton River, landowners and local, state, and federal stakeholders on Teton Creek aimed at turning Teton Creek back into a productive spawning ground and migratory route for Yellowstone cutthroat trout. The goal is to rebuild stream banks and riparian zones, stabilize the stream channel, improve stream flows and create vital trout habitats.
