Crow Wing River Fishing Guide: Smallmouth Bass From Pre-Spawn Through Post-Spawn
If you want to fish for smallmouth bass on the Crow Wing River with a guide who knows every bend of it, here's what you need to know: the window is short, the water is gin-clear, and the fishing is as good as it gets anywhere in Minnesota.
The Crow Wing is a tributary of the Upper Mississippi, flowing into the main river just south of Brainerd. Every spring, big smallmouth push out of the Mississippi and run up the Crow Wing to spawn. For roughly six weeks in May and June, this five-mile stretch between the Pillager Dam and the river mouth becomes one of the best smallmouth fisheries in the state — and almost nobody is talking about it.
I'm Steve Washburn, the guide behind NorthFish Angling. I run guided fly fishing and light tackle trips on both the Upper Mississippi and the Crow Wing, and the Crow Wing in spring is one of my favorite stretches of water to share with clients. Here's why — and how to plan a trip around the season.
Why the Crow Wing River Is a Smallmouth Factory
The Crow Wing has everything smallmouth bass need to spawn successfully. The bottom composition is a mix of sand, gravel, rock, and boulders — ideal bed-building material. The water is clean, clear, and full of life: healthy weed growth, thriving insect populations, crayfish, and baitfish. It's the kind of river where the entire food chain is firing.
But what makes the Crow Wing special isn't just the habitat. It's the location. Because it's a direct tributary of the Mississippi, the river draws a surge of big spawning smallmouth upstream every spring. These aren't just resident fish — they're Mississippi River smallmouth, including large females, moving into the Crow Wing specifically because the spawning conditions are better here than on the main river. The Mississippi runs stained or muddy most of the year. The Crow Wing runs clear. Smallmouth are sight predators. If they can't see, hunting is harder. They gravitate to clear water, and the Crow Wing delivers it.
The result is a concentrated population of aggressive, healthy fish in a relatively short stretch of river. That's what makes a guided trip here so productive during the spring window.
When to Fish the Crow Wing: The Spring Window
Smallmouth start leaving their wintering holes and moving upriver toward spawning areas sometime in April, depending on water temperatures and daylight. Many of these fish choose the Crow Wing because of its ideal conditions. By May, the pre-spawn is in full swing.
Here's how the season breaks down:
Pre-Spawn (Early to Mid-May)
Fish are holding in areas adjacent to spawning flats, feeding aggressively as they stage for the spawn. This is reaction-bite fishing — the fish are hungry and competitive. It's some of the most exciting fishing of the year.
Spawn (Mid-May Through June)
Fish move up onto beds. The fishing shifts from reaction to finesse — you're targeting fish that are guarding beds rather than chasing food. Sight-casting opportunities open up when you've got sun and low wind, because the water is clear enough to see fish on beds. This is something you'll almost never get on the Mississippi.
Post-Spawn (Late June Into Early July)
Once spawning wraps up, the fish get aggressive again. They're recovering and feeding hard. Post-spawn fishing on the Crow Wing can produce some of the best days of the season for numbers and action. But the clock is ticking — as water levels drop through late June and into July, fish begin moving back out to the Mississippi. By mid-July, the Crow Wing's spring window is effectively closed.
The takeaway: May and June are the months. That six-week stretch covers pre-spawn through post-spawn, the water is high enough to navigate, weed growth isn't a factor yet, and the fish are concentrated. If you're planning a trip, that's your window.
Techniques That Work on Clear Water Smallmouth
The Crow Wing fishes differently than the Upper Mississippi, and the biggest reason is water clarity. Clear water means stealth matters. Long casts, lighter presentations, and a quieter approach will consistently outfish anything aggressive or sloppy.
Fly Fishing
During the pre-spawn and post-spawn, Game Changers and Clouser Minnows are the go-to patterns — these are reaction flies designed to trigger strikes from aggressive fish. Once fish are on beds during the spawn, we switch to finesse: crawfish imitations worked slowly near the bed. Fluorocarbon leaders run longer on the Crow Wing than on the Mississippi because the fish can see your line in this water.
Light Tackle
The approach mirrors the fly game. Pre-spawn and post-spawn call for soft jerkbaits and small crankbaits — moving baits that cover water quickly. During the spawn, finesse presentations like ned rigs fished in and around beds produce best. Smaller profile baits across the board. The Crow Wing punishes anything oversized or loud.
One of the best parts of fishing the Crow Wing during this window is sight-casting. When conditions line up — sun overhead, low wind — you can see fish on beds and watch them eat. That's a rare experience on any river in Minnesota, and it's something you'll never get on the Mississippi.
What a Guided Trip on the Crow Wing Looks Like
We launch from the Crow Wing State Park boat ramp and head downriver about half a mile to the mouth of the Crow Wing, where it meets the Mississippi. From there, we run up the Crow approximately five miles to the Pillager Dam. That five-mile section is the fishery — and we typically cover all of it in a day.
The boat is a 2024 Stealthcraft 1654 Power Drifter with a Mercury 60/40 jet outboard — purpose-built for shallow, clear rivers like this. It's quiet, it drafts minimal water, and it lets us access stretches that most boats can't reach.
Both fly and light tackle anglers fish well on the Crow Wing. The river is relatively shallow with good wading structure, but the drift boat gives us the ability to cover the full section efficiently and position precisely on productive water.
During the spring window, fish range from scrappy juveniles to 20-inch spawning females that push up from the Mississippi. The quality fishing — and the sheer number of fish holding in this stretch — is what makes the Crow Wing stand out. Some of my best days guiding for river smallmouth have happened right here in May and June.
Book the Spring Window Before It's Gone
The Crow Wing River smallmouth season is a defined window: roughly the first week of May through late June. Once water levels drop and fish migrate back to the Mississippi, the fishing changes completely. This isn't a fishery you can show up to in August.
Trips are $500 for a full day (6 hours) or $350 for a half day (4 hours), with a maximum of two anglers per boat. May and June dates fill early, so if the Crow Wing is on your list, book in advance to lock in your spot.

If you're looking at summer dates after the Crow Wing window closes, check out our Upper Mississippi fly fishing trips — the Mississippi fishes strong from May through October, with peak smallmouth action through the summer months. Between the two rivers, there's a trip for every part of the season.
