Post-Spawn Walleye Firing on Red and Missouri Rivers
Water temperatures at 58°F on the Red River of the North (USGS gauge 05054000, recorded May 23) signal the prime post-spawn walleye feeding window. Jason Mitchell Outdoors is headlining this moment as 'May Walleye Craziness,' with content from North Dakota waters including Devils Lake showing aggressive walleye behavior. Guide Jason Freed of AnglingBuzz is dialing in slip bobber rigs and big-water walleye presentations for exactly this seasonal window. The Red River is flowing at 751 cfs, a moderate fishable level that keeps current seams and wing dam structure within reach. On the Missouri drainage, channel catfish and northern pike round out the opportunity as warming water drives predator feeding. Fishing the Midwest notes that rivers through summer can deliver outstanding action, particularly on shallow flats with a casting approach. With a First Quarter moon building, dawn-to-midmorning and dusk windows should favor active walleye bites through the Memorial Day weekend.

What's Next
The 58°F water reading from late May 23 puts the Red River squarely in the sweet spot for walleye. Post-spawn females have had time to recover, and the gradual warming typical of late May in the Northern Plains should keep fish active and feeding through the coming days.
Jason Mitchell Outdoors has been running deep on shallow walleye content this week, with 'Trolling Shallow Walleye' landing alongside 'May Walleye Craziness' as clear indicators that walleye are holding and chasing in the upper column rather than hugging bottom. Shallow trolling presentations and the slip bobber setups detailed by AnglingBuzz guide Jason Freed are worth having rigged and ready before any session this week.
If temperatures continue their seasonal climb into the low-to-mid 60s over the Memorial Day weekend, expect walleye to shift into classic post-spawn holding patterns: wing dams, riprap shorelines, current breaks below bridges, and the first deeper bends below shallow spawning flats. Current seams on the Red at 751 cfs provide good structure without pushing fish completely off their lies.
Northern pike are a reliable secondary target this time of year. Warming water in the low-to-mid 60s triggers active predatory feeding, and weed edges and back-current eddies on both the Red and Missouri tributaries can hold fish from first light through midmorning. A First Quarter moon building through the week points to improving activity each successive dawn window.
On the Missouri River side of the state, channel catfish typically begin pre-spawn staging once water temperatures approach the low-60s range, making the coming week a good time to probe deeper holes and current shelves with cut bait or prepared baits.
For the Memorial Day weekend, focus morning sessions from first light to around 9 a.m. and again in the two hours before sunset. Midday heat can push walleye deeper on bright, calm days, but overcast skies and any wind chop will extend the feeding window considerably. Fishing the Midwest recommends a casting approach on shallow flats during the early season: work parallel to current seams and run jig-and-minnow presentations slowly upstream to cover water efficiently.
Context
Late May in North Dakota typically marks the transition from post-spawn recovery to full summer feeding patterns for walleye, and the 58°F reading from USGS gauge 05054000 is right on schedule for this period. Most years the Red River and Missouri River system reach the mid-50s to low-60s range between mid-May and early June, creating the window that regional anglers plan their biggest trips around.
Jason Mitchell Outdoors, a North Dakota-rooted fishing media operation, labels this exact stretch 'May Walleye Craziness,' which aligns with the historical feeding peak that follows spawning pressure and recovery time. Post-spawn walleye in ND rivers tend to stage near the same structural features used during the spawn before gradually migrating toward deeper summer holding areas as water temperatures climb past 65°F. That transition is still several weeks out at current readings, leaving a productive window ahead.
No direct year-over-year comparison from state agency reports or charter testimony appears in this week's intel to benchmark this season against prior years on the Red or Missouri specifically. The AnglingBuzz and Jason Mitchell Outdoors content points to active walleye behavior consistent with expectations for this date, but without a hard comparison it would be an overreach to call the season early or late.
What is clear: at 751 cfs, the Red River is running at a moderate, fishable stage for late May. Historically, spring snowmelt floods on the Red can push flows dramatically higher and cloud the water enough to shut down sight-feeding species for weeks. A moderate flow like the current reading is favorable and suggests fish have had time to settle back into post-flood structural positions rather than scatter across floodplain edges. Check state regulations before harvesting, as season dates and possession limits on both the Red and Missouri can change from year to year.
