Project Overview

Two areas along the Madison River have been identified for side channel restoration projects. The projects will include a variety of restoration elements designed to provide better spawning and rearing habitat, enhanced vegetation and stream complexity, and long-term ecosystem resilience.

The Madison River supports a nationally recognized fishery that is central to recreation, local businesses and nearby communities. Healthy trout populations depend on high-quality spawning and early-life habitat. Spawning gravels and thermal refuge are key habitat components that help trout reproduce successfully and improve survival of young fish.

The projects are at two locations about 11 river miles apart on the Madison River:

  • Upstream of Hyde Creek on BLM and state land (Wall Creek WMA) — River Mile 77.7
  • Near Morgan Gulch on BLM land — River Mile 66.6
  • Pending project approvals, construction is expected to last from September to November 2026.

Impact on Recreationists

Impact on Recreationists

Beginning in September 2026, visitors on the Madison River may see temporary construction and revegetation activities. Please help keep everyone safe and support restoration success by following posted signage and directions in the project area. These projects will not affect any major land access points, river access at common put-in and take-out locations, or mainstem fishing access.

What Recreationists should expect:

  • Avoid affected areas and equipment during construction and revegetation.
  • Some areas may include temporary work zones and active construction access along the river corridor.
  • Impacts will be time-limited to the construction window (pending approvals) and will help create long-term habitat improvements.
  • Once the projects are complete, anglers are asked to avoid fishing in the restored side channels during spawning seasons to minimize impacts to vulnerable spawning trout. This will ensure the intended benefits to the mainstem fishery are realized.

The Madison River Side Channel Restoration Projects offer numerous benefits, including:

  • Improved spawning habitat: Restoration elements are designed to increase access to and quality of spawning gravels and improve conditions that support successful reproduction.
  • Better rearing habitat for young trout: Side channel improvements are intended to create higher-quality habitat where juvenile fish can grow and survive before entering the mainstem.
  • Enhanced vegetation and stream complexity: Work will strengthen riparian vegetation and add complexity that supports aquatic life and improves ecosystem function.
  • Long-term resilience: Restoration is intended to improve the river’s ability to function well over time, supporting habitat stability and overall river health.
  • Support for a world-class fishery: By improving recruitment to the mainstem fishery, the projects help sustain a river that supports anglers, outfitters, and local communities.

This project is a collaborative effort involving several key partners:
