Crews are working on the upper Madison this fall, rebuilding two historic side channels between Lyons Bridge and Varney Bridge. The Fish and Wildlife Commission is set to vote Wednesday, October 14, on a rule that would close both channels to fishing and wading for the entire year. FWP's written rationale for that rule talks about protecting trout "seasonally." The rule text does not. Montana Fish, Wildlife & Parks is restoring this habitat to raise trout numbers in the main river, and it plans to keep anglers' boots out of it. Where exactly that restriction begins will be marked by signs on the bank, not by a map.
The Rule Text, Word for Word
This is Proposal 28 in FWP's 2027–2028 fishing regulation package for the Commission. The earlier scoping draft numbered the same item Proposal 31. It adds one line to the Lyons Bridge to Varney Bridge section of the Madison regulations:
Hyde Creek and Morgan Gulch side channels closed entire year to fishing and wading as posted.
The rest of the reach's rules would stay as they are: catch-and-release for trout, with anglers 14 and younger allowed one trout a day, and artificial lures only. The proposal closes "fishing and wading," which is broader than a fishing closure alone. If it passes, crossing a closed channel on foot to reach the main river would also be off the table inside the posted area.
The proposal also covers a second site well downstream. It would close side channels and areas around islands just upstream of the Highway 84 bridge, again for the entire year and as posted. That stretch sits near Norris, below the dam. FWP says a similar phase of side-channel work was finished there in 2025.
Where the Two Channels Sit
NorthWestern Energy's project page puts the two sites about 11 river miles apart. FWP's printed fishing access site guide lists river miles for the bridges. Going downstream, the order looks like this:
- Lyons Bridge, River Mile 88
- Upstream of Hyde Creek, River Mile 77.7, on BLM land and FWP's Wall Creek Wildlife Management Area
- McAtee Bridge, River Mile 71
- Near Morgan Gulch, River Mile 66.6, on BLM land
- Varney Bridge, River Mile 60
So the Hyde Creek work sits in the upper half of the reach, between Lyons and McAtee. That's the same corridor as the BLM's Palisades and Ruby Creek access areas. Morgan Gulch sits in the lower half, between McAtee and Varney. None of the published materials include a map, coordinates, or a written boundary for either closure. The rule only says "as posted."
What the Crews Are Building, and Why NorthWestern Is Involved
FWP announced the work in an August 5 news release. It's described as part of a multi-year effort to bring back flows and spawning conditions in several historic side channels. The partners are NorthWestern Energy, the Madison River Foundation, FWP, the Bureau of Land Management and Geum Environmental Consulting. Construction is scheduled for September through November. FWP says it will not affect any major land or river fishing access points. NorthWestern adds that put-ins, take-outs and access to the main river stay open. Visitors may see temporary work zones and construction access along the river corridor.
In the same release, NorthWestern Energy hydro compliance professional Jon Hanson said the projects help the company in "fulfilling our responsibility to mitigate the effects of our hydropower operations." Mia Cignoni, conservation programs manager for the Madison River Foundation, described the goal as "giving the river back some of the habitat and natural processes that have been diminished over time." The foundation lists Morgan Gulch and Hyde Creek as priority restoration sites for spawning, rearing, overwintering and refuge habitat. Fly Fisherman covered the planned restoration on August 27, but not the regulation that would come with it.
A Seasonal Reason for a Year-Round Rule
FWP's rationale opens by saying the regulation would "seasonally protect Madison River trout" in the constructed channels and island habitat. It ends by saying "the proposed closure window will span the spawning and incubation period for rainbow and brown trout." So the rationale talks about a window. The rule says "entire year."
Spawning alone covers much of the calendar. General Montana guidance puts rainbow trout spawning in March through June and brown trout spawning in October through November. One Montana outfitter, Montana Angler, describes Madison browns moving into the river system in late September and October, with pre-spawn movement generally lasting into mid-November. Then add the weeks that eggs sit in the gravel after each spawn. Spring and fall together already take up a large share of the year.
The rest of FWP's reasoning covers the remaining months. Side channels and islands hold gravel that "directly provide or replenish and create spawning habitat." Their slower edges also give juvenile trout "summer and winter refugia from predators." FWP adds that these shallow, slow areas are especially exposed to angling pressure because they are easy to reach and spawning fish gather there. Adult trout use the channels in spring and fall. Young trout use them in summer and winter too.
The voluntary guidance from the project partners still reads seasonally. Both FWP and NorthWestern ask anglers to avoid the restored channels during brown and rainbow spawning seasons once the work is done. That request stands on its own this fall, whatever the Commission decides.
Who Weighed In
FWP says the proposal went through meetings with the Region 3 Citizens Advisory Council, Madison Gallatin Trout Unlimited, the Fishing Outfitters Association of Montana, Montana Trout Unlimited, the Madison River Foundation and the Madison Conservation District. Between 100 and 200 people attended, including state legislators and county commissioners. FWP reports "good support" and says no changes were suggested. Region 3 Enforcement had no concerns.
Statewide, FWP logged 261 comments on 41 scoped department proposals during scoping, along with 94 proposals sent in by the public. On the Madison item, the scoping comment responses show Montana Trout Unlimited supporting the closures while pointing out that "as posted" boundaries need to be clear to the people using the river. One commenter opposed closing Hyde Creek or Morgan Gulch. FWP answered that the reconnected channels are meant to create spawning and rearing habitat that is vulnerable to fishing pressure and trampling.
In the Commission's September comment period, Montana Trout Unlimited raised a practical point for anyone who floats the reach. The group said posting would need clear communication, including keeping anglers from anchoring at the ends of islands and damaging the restoration. The Montana Outfitters and Guides Association commented on a separate matter. It supported holding off on spawning closures in the Madison's main channel until more monitoring is done. That comment did not address the side channels.
The package made one other change on the Madison during review. FWP dropped a proposed district-standard pike-harvest change for the river and kept the side-channel closures. FWP has a separate Madison River workgroup that develops recommendations to the Commission on commercial trip allocations, outfitter permits and walk/wade and rest/rotation rule language. The side-channel proposal does not say it changes any of those.
Wednesday's Vote and the March Calendar
The Commission meets virtually by Zoom at 8 a.m. on Wednesday, October 14. Some earlier FWP materials list October 15, but the updated meeting page shows the 14th. The comment period closed September 24. FWP's memo lays out three options. The Commission can adopt the package as written, propose other changes that would need more analysis, or carry the 2025 regulations forward into 2027–28. FWP recommends adoption.
Even if it passes, nothing changes on the water right away. Montana's current fishing rules run March 1, 2026 through February 28, 2027, following a license year that starts each March 1. FWP hasn't published an effective date for the new booklet, but the calendar points to March 1, 2027. That's around the start of the rainbow spawning window in the general guidance above.
Until then, this fall's brown trout run is covered only by the partners' request to stay out of the channels during spawning, plus whatever signs go up as the construction wraps up in November.
