Mississippi River fishing seasons on Pools 8 and 9

Most sport species on Pools 8 and 9 run a continuous season under Wisconsin’s boundary-water chapters. What changes is not a red “closed” stamp on the calendar — it is water temperature, current, and which species are worth the drive. Use themississippi river fishing for place, and this page for time.

Are any major species closed by calendar here?

Walleye, sauger, bass, pike, channel and flathead catfish, and the listed panfish run continuous seasons in the Wisconsin NR 21 / NR 22 sport tables we cite. Lake sturgeon and paddlefish show no open season. Always re-read the chapter before a trip — administrative code can move without a blog post announcing it.

Spring is when thewalleye playbook matters most — bag structure at the dam included. Summer nights push anglers toward thecatfish patterns. Fall mixes both. Winter is access and weather limited, not a different statute for most species.

What should you check before you drive?

Stage on the pool page (USGS gauges embedded on theGenoa-to-La Crosse water and theLansing stretch notes), wind for your launch, and a light/pressure score from thebest fishing time calculator. High, dirty water after a tributary dump is a different day than a clear, falling river even in the same calendar week.

When is a license waived?

Wisconsin waives the license requirement on four weekend days a year (first Saturday and Sunday in June, third Saturday and Sunday in January) on these boundary waters. Bag limits still apply. Details and the resident rule live in thelicense finder, not here.

No fishing license is required on the Wisconsin boundary waters on the first Saturday and following Sunday in June, and on the third Saturday and following Sunday in January

Questions anglers ask

Is there a closed walleye season on the Mississippi here?

No. Wisconsin lists walleye and sauger as continuous on these boundary waters. Limits change by pool; the calendar does not shut the season.

Does ice fishing change the bag limits?

Bag and length rules still come from the same chapters. Ice only changes access and safety. Confirm ice conditions locally — this site does not publish ice thickness.

Should I trust solunar calendars for this river?

Treat them as tradition, not proof. Our best fishing time calculator scores light, moon and pressure separately and labels how strong the evidence is for each factor.
