139 CFS — wading range
Solid water for fishing.

The Boardman — also known as the Ottaway River, the name the Anishinaabek carried for it long before a sawmill went in at its mouth in 1847 — is the coldwater spine of the Grand Traverse region, running roughly 28 miles from the confluence of its North and South branches down to West Grand Traverse Bay in downtown Traverse City. What sets it apart isn't a single famous run: this is a genuinely wild trout river you can fish inside city limits, and it's the water the Adams was born on — Len Halladay tied the first one here for Charles Adams around 1922. The upper river holds self-sustaining brook trout, the middle holds heavy browns, and the system hasn't been stocked with trout since 1972.

It fishes small and technical up top and bigger and pushier as you go down. Above Brown Bridge the river is 20-30 feet wide, gravel-bottomed, hemmed by cedar sweepers and deadfalls — roll-cast water where a Parachute Adams or Elk Hair Caddis and quiet feet matter more than distance. Below Brown Bridge the gradient picks up through the reaches where three dams used to sit, and you get faster shallow water dumping into deep, dark holes that hold browns worth a Sculpzilla or a big articulated streamer at low light. Summer flows sit right around 140 CFS at the Mayfield gauge, and heavy groundwater keeps the upper and middle river cold and fishable when nearby freestones cook — which is why the Hex draws a crowd of night anglers in late June and early July.

The big story here is the dam removals. Brown Bridge (2012), Boardman (2017), and Sabin (2018) all came out, and the downtown Union Street Dam was removed through 2025 — one of the largest dam-removal efforts in the Midwest, reconnecting roughly 160 miles of river and tributary and dropping summer temperatures. The old impoundment ponds are now free-flowing restored channel, and the fishery is still settling into its new shape. Honest trade-off: the lower river through Boardman Lake and downtown warms in summer and turns into a steelhead-and-salmon fishery in fall and spring, with smallmouth and the odd carp when it's warm — so treat the lower reach as migratory and warmwater water, not a summer trout stretch. Much of the river carries a state Natural River designation, and 36 miles are Blue Ribbon.

Fishing Reports

Species

  • Brook Trout
    Wild, self-sustaining · May-Sep · 6-12"

    The river's signature wild fish, densest in the uppermost reaches from the Forks down through the upper river. Native, with no stocking since 1972. Fish dries and small nymphs in the tight cedar-lined water.

  • Brown Trout
    Wild, self-sustaining · May-Jun (Hex), Sep-Oct (streamers) · 10-20"+

    Best numbers of larger fish hold in the middle river's deep holes through the former dam sites. Night Hex fishing in late June and fall streamers at low light move the biggest browns.

  • Rainbow Trout
    Wild, resident · Apr-Oct · 8-14"

    Resident rainbows are present through the system and distinct from the migratory steelhead that run the lower river. Take them on the same dries and nymphs as the brookies.

  • Steelhead
    Migratory run · Mar-Apr, Oct-Dec · 5-12 lb

    Run up the lower river below Boardman Lake and the former Union Street Dam from Grand Traverse Bay. Spring and fall/winter chrome on egg patterns, streamers, and baitfish flies; the Chinook and coho salmon run the same lower water in fall.

Ideal wading flow120–180 CFS
Blow-out>300 CFS
Ideal water temp50–62°F

Late June into July is the peak trout window — Hex, Brown Drake, and Sulphur nights, with the biggest browns coming up after dark. May brings Hendrickson and Sulphur dry-fly fishing plus spring steelhead in the lower river, and September-October is brown-trout streamer season and the fall salmon/steelhead run. The upper and middle river stay cold and fishable through summer thanks to heavy groundwater; the lower river below Boardman Lake warms and is better fished early or targeted for bass and migratory fish.

Sections

6 sections on this river

Lower Boardman through Traverse City

Wade & FloatSteelhead · Salmon · Smallmouth · Carp

Warmer, urban river below Boardman Lake and the former Union Street Dam, running U-shaped through downtown Traverse City to West Grand Traverse Bay. In-town, walk-in water that warms in summer and comes alive on the seasonal runs from the bay now that dam removal has reopened passage.

Best for: Steelhead in fall, winter, and spring plus Chinook and coho salmon staging in fall — egg patterns, streamers, and baitfish flies on heavier rods — with smallmouth bass and carp in the warm months.

North Branch

WadeBrook Trout · Rainbow Trout

Small, wadeable brook trout tributary draining from the northeast into the Forks. Tight, cold headwater creek water — technical, low-pressure, and best fished with short dries and small nymphs.

Best for: Wild brook trout on Parachute Adams, Elk Hair Caddis, and small nymphs.

Middle River to Beitner

WadeBrown Trout · Rainbow Trout

Faster gradient and shallow gravel riffles dropping into deep, dark holes through the former Boardman (2017) and Sabin (2018) dam sites down to Beitner Road. This is the heart of the dam-removal restoration and holds the river's larger browns; much of it borders private land, so mind your access.

Best for: Larger brown trout on streamers — a Sculpzilla or beadhead Woolly Bugger at low light — plus Hex and Brown Drake dry action after dark and nymphing the holes.

The Forks & Upper River

WadeBrook Trout · Brown Trout · Rainbow Trout

Small, intimate, wild brook trout water 20-30 feet wide from the North/South Branch confluence down toward Brown Bridge. Shallow gravel runs, cedar sweepers, deadfalls, and tight overhead cover — roll casting and short, accurate presentations. Heavy groundwater keeps it cold and fishable all summer, and the USGS Mayfield gauge sits on this reach.

Best for: Wild brook trout and resident rainbow trout on dries and small nymphs — Parachute Adams, Elk Hair Caddis, small BWO patterns, Pheasant Tail, and Hare's Ear.

South Branch

WadeBrook Trout · Rainbow Trout

Small brook trout tributary rising near South Boardman and Kalkaska and joining the North Branch at the Forks. Intimate, gravel-bottomed headwater water with tight cover.

Best for: Wild brook trout on dries and small nymphs.

Brown Bridge Reach

WadeBrook Trout · Brown Trout · Rainbow Trout

Restored free-flowing channel through the Brown Bridge Quiet Area where Brown Bridge Pond used to sit before the dam came out in 2012. New gravel, restored floodplain, and transitional water — quick shallow runs dropping into deeper slots. The most-visited of the restoration reaches, still evolving.

Best for: Brook trout and brown trout — dries during hatches, nymphing the deeper slots, and small streamers.

Regulations

Current fishing rules and restrictions

The Boardman/Ottaway follows Michigan's Inland Trout & Salmon Stream gear-type system, and different reaches carry different type designations — check the sign at the access point and the current Michigan Fishing Guide for the exact reach. It's a Type 1 trout stream upstream, roughly down to Beitner Road, and Type 4 from Beitner Road to the mouth, with much of the river carrying a state Natural River designation and 36 miles rated Blue Ribbon.

  • Type 1 (general regulations) on the upper river down to about Beitner Road; standard inland-trout gear and limits apply.
  • Type 4 from Beitner Road to the mouth — extended-season, migratory-oriented regulations on the lower river.
  • Upper river follows the general inland trout season: last Saturday in April through September 30.
  • The lower river below the former Sabin Dam stays open year-round for steelhead and salmon.
  • Michigan fishing license required (age 17+); an all-species license is needed to fish for trout and salmon.
  • Boardman River Natural River designation applies across much of the corridor — mind the streamside development and access rules.

Type 1/Type 4 reach boundaries and any gear-restricted sub-reaches can change year to year — confirm against the current Michigan Fishing Guide before you fish. Much of the middle river threads private land, so know your access.

Grand Traverse & Northwest

Pine RiverMI

The fastest trout river in the northern Lower Peninsula — a cold, gravel-bottomed freestone that drops roughly seven feet per mile above Tippy Dam. Everything in it is wild: two strains of brown, headwater brook trout, and an unusual population of acrobatic McCloud-strain rainbows. A National Scenic River, and one of Michigan's busiest summer canoe runs, so fish it early, late, or after Labor Day. Trout season only — closed October 1 through late April.

Upper Manistee RiverMI

Michigan's finest self-sustaining trout stream — 60-plus miles of cold, spring-fed water near Grayling holding wild browns, brook trout, and rainbows, with a flies-only reach from M-72 to CCC Bridge and the state's marquee after-dark Hex hatch.

Other regions

Au Sable RiverMI

The spring-fed river American trout conservation was born on — Trout Unlimited was founded on its banks in 1959, and the flies-only, catch-and-release "Holy Water" below Grayling still grows wild browns and brookies. It's a match-the-hatch dry-fly river whose signature event is the after-dark Hexagenia hatch in late June.

Jordan RiverMI

Michigan's first designated Natural River (1972) — a small, cold, spring-fed brook-trout stream running the protected Jordan Valley to Lake Charlevoix. Technical, tight-canopy wade water up top for native brookies, a float below Graves Crossing for the Hex and its biggest browns, and lake-run fish in the lower river.

Lower Manistee RiverMI

The big migratory tailwater below Tippy Dam near Wellston — thousands of Lake Michigan steelhead, Chinook, and coho stack under the dam, drawing spey swingers and drift boats fall through spring, over a resident 20-inch-plus brown trout fishery in the cold water up top.

Muskegon RiverMI

West Michigan's do-everything tailwater below Croton Dam — cold, steady Consumers Energy releases hold wild browns and rainbows up top while some of the Great Lakes' heaviest steelhead and king-salmon runs stack the length of it. A big drift-boat river and Midwest spey destination, famous for its Gray Drake hatch.

Pere Marquette RiverMI

Michigan's blue-ribbon spring creek and a National Wild & Scenic river — the famous 8.5-mile flies-only, catch-and-release water from M-37 to Gleason's Landing grows wild browns descended from the first brown trout ever stocked in North America, and the lower river fills with Lake Michigan steelhead, Chinook, and coho on the fall and spring runs. Log-jam water fished by wade and low-profile drift boat, with a signature after-dark Hex hatch in late June.

Pigeon RiverMI

The Pigeon threads the wildest country in Michigan's Lower Peninsula — the 106,000-acre Pigeon River Country State Forest, home of the state's elk herd. A cold, spring-fed, tannin-tinted stream holding wild brook, brown, and rainbow trout, it fishes small and technical up top and opens to lake-run browns near Mullett Lake. Blue Ribbon and Natural River water.
