River smallmouth bite holds as Mississippi pools run high

What's biting

What's next

With flow sitting at 20,400 cfs on the Mississippi gauge as of this evening, the near-term picture is about current management more than temperature. If no additional rain moves through the Upper Midwest over the next 2-3 days, expect flow to ease gradually, which should pull fish out of the tightest eddies and back toward more typical current-break holding spots by the weekend. Until then, backwaters, wing dams, and current seams along shoreline structure are the higher-percentage water — Field & Stream's smallmouth notes on shaded cover and current edges apply directly here, since river smallmouth use the same seam-and-eddy logic anywhere flow is elevated.

Walleye should keep responding to the weed-edge pattern Fishing the Midwest is highlighting for this point in the open-water season. As flows stabilize, working the transition between weed growth and deeper current channels is worth prioritizing, particularly in the morning and evening windows when light penetration is lower and fish push shallower to feed.

Largemouth bass should stay aggressive through the coming stretch. Tactical Bassin's July breakdown notes bass metabolisms peak with rising summer heat, which tracks for backwater sloughs and slack-water pockets off the main channel where warmer, calmer water concentrates baitfish. Early morning remains the highest-percentage window before the sun gets high and pressure builds, consistent with the general pattern of summer largemouth backing off as light and heat increase through the day.

With the moon in its Last Quarter phase, expect feeding activity to be moderate rather than sharply concentrated around a single major period — plan around dawn and dusk rather than betting everything on a single moon-driven window. Catfish should also stay a solid option through this stretch; elevated, slightly off-color flow is typically productive for channel cats working current breaks and current-swept structure, even without a specific report confirming it this week.

Weekend anglers should watch the gauge again before heading out. If flow has dropped meaningfully from the 20,400 cfs reading, expect clearer water and a shift of fish back toward main-channel structure; if it holds steady or climbs, stick with the backwater and current-seam pattern described above.

Context

Typical early July conditions on the Upper Mississippi pools between Prescott and La Crosse settle into a fairly stable summer pattern: moderate, predictable flow, warming water, and fish pushed toward weed lines, wing dams, and current seams as the open-water season matures. Fishing the Midwest's coverage this week, describing the 2026 open-water season as "in full swing," suggests the seasonal timing itself is on schedule even with the elevated flow reading.

A reading of 20,400 cfs on gauge 05344500 is on the higher side for this point in the season on this reach, which points to recent upstream rainfall or reservoir release activity rather than a purely seasonal pattern. Higher flow generally means more turbidity, stronger current pushing fish out of open water and into eddies, backwaters, and shoreline cover, and slightly delayed warming compared to a lower-flow year, since more water volume takes longer to heat.

We don't have a direct multi-week or year-over-year comparison for this specific gauge in the angler intel available, so it's worth being honest that this note can't quantify exactly how unusual the current flow is against a longer-term baseline. What is clear from the available sources is that the broader regional bite (smallmouth on seams, walleye on weed edges, largemouth on shallow cover) is behaving as expected for early July, even if the water itself is running higher than the calm, stable conditions this stretch of river typically sees by now.
