To learn more about the Teton Creek Restoration Project and their current conservation efforts,
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 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.
