Full-moon catfish and summer bass prime up on the Mississippi

What's biting

What's next

With USGS gauge 07289000 reading 835,000 cfs, the main-channel Mississippi is running hard and turbid through this stretch. Over the next two to three days, flows should remain in a similar range unless upstream precipitation changes the picture. Check USGS WaterWatch for updates before launching.

The full moon tonight is the single biggest trigger on the calendar right now. Catfish, particularly blue cats and flatheads, are known to feed aggressively during full-moon nights on big river systems, and Field & Stream's summer catfish feature captures exactly this pattern: a subtle tap on the rod tip, then the rod doubles over. Work cut shad or skipjack along current breaks, wing dams, and the soft edges where fast water meets slack. Drift rigs and circle hooks are the workhorse setup. Expect the best catfish action from dusk through midnight, with a secondary window near first light.

For bass, Tactical Bassin's July breakdown describes the split that happens as summer deepens: some fish stay shallow in the early morning targeting bream and surface prey, while others move deep and relate to shad schools. On the Mississippi system, fish the slack-water pockets, oxbow cuts, and timber edges first thing with topwaters or swim jigs, then transition to deeper presentations once the sun climbs. Wired 2 Fish's July lure roundup notes that in the South, fish relating to current are still very much in play, making river mouths and tributary confluences productive through midday.

Bluegill and panfish action should stay solid through the weekend, particularly in the calmer backwater sloughs and oxbows connected to the main river. Wired 2 Fish reports that fly-rod anglers have been scoring well on jumbo bluegills with dice and urchin-style bugs, a technique equally effective under a bobber on conventional gear. Prime timing is mid-morning before surface temperatures peak.

The full-moon energy carries through the next several evenings, making this one of the more productive catfish windows of the year on a big-river system. Plan evening launches and night sessions accordingly, and consider staging near known deep-hole catfish structure before last light.

Context

Late June and early July on the Mississippi and Pearl Rivers sit squarely in peak summer mode. The post-spawn recovery phase is over, and fish have settled into predictable seasonal routines driven by heat, current, and bait availability. On the Mississippi, flows in the 700,000 to 900,000 cfs range are typical for late spring runoff tapering into summer baseflow; the current reading of 835,000 cfs at USGS gauge 07289000 is elevated but not outside the normal range for this time of year at this latitude.

Catfishing on the lower Mississippi has historically been at its annual best from late May through August, with the full-moon window in June and July considered prime by generations of river anglers. This year's timing aligns well with that pattern. Water temperature data was not available in today's gauge reading, but late June typically places the Mississippi in the 80 to 84 degrees F range through this stretch, which sits in the optimal feeding zone for blue cats and flatheads holding in deep-channel holes during daylight.

Bass on the Pearl River follow a similar summer playbook but in a more intimate setting. The Pearl tends to run clearer than the Mississippi in summer, which makes lure presentation more consequential. Finesse approaches, including the Neko rig and soft jerkbait techniques highlighted by Tactical Bassin, can outperform power fishing when the sun is high and water visibility is good. Early morning and evening feeding windows are compressed compared to the spring.

No state agency reports or local guide dispatches from this specific region were available in this cycle's intel feed to benchmark this season against prior years. Based on the gauge data and general seasonal context from Wired 2 Fish and Tactical Bassin, the Mississippi and Pearl system appears to be on a typical late-June trajectory. Peak summer patterns are expected to hold through mid-August before early cooling signals begin shifting fish behavior.
