Trout Unlimited has reported restoring more than 400 miles of fish habitat on national forests in recent years, and Montana-specific TU work cited in public materials includes restoring 2 miles in the Ninemile Valley.

Quick Scoop

The public TU material I found does not give a clean “2025 Montana total” in one place. What it does show is:

  • More than 400 miles of fish habitat restored across national forests in recent years.
  • 2 miles restored in Montana’s Ninemile Valley in one cited example.
  • TU Montana’s site is the right place to confirm any newer 2025 state total, but the accessible page result I found did not expose a specific mileage figure.

Best read on the number

If you meant TU Montana’s statewide 2025 stream-miles restored , I can’t verify a precise total from the accessible public source I found. If you meant TU overall work that includes Montana , the strongest verified figure in the material is over 400 miles of fish habitat restored, plus 700 miles reconnected by removing barriers.

Context

Montana has been a major focus area for Trout Unlimited, especially in drainages affected by mining and habitat fragmentation. One example from TU’s public materials is the Ninemile Valley restoration, where they say they restored two miles of mainstem habitat and reconnected tributaries.

TL;DR

  • Verified TU-wide recent restoration: 400+ miles.
  • Verified Montana example: 2 miles in Ninemile Valley.
  • Exact 2025 TU Montana statewide total: not confirmed from the source available here.
