Frequently asked questions
- What special fishing regulations apply at Mississippi River Pool 16?
- Mississippi River Pool 16 carries one special-regulation overlay that overrides Iowa's statewide 2026 rules. It reads: "Upper Mississippi River Joint Compact reciprocity (IA + IL Mississippi main stem); walleye + sauger combined 6 / day (12 possession) + 15 in min walleye (release all 20–27 in, one over 27 per day); smallmouth + largemouth bass 14 in min + 5 / day combined (10 possession) boundary-river limit; channel + blue + flathead catfish combined NO daily limit on the Mississippi River (no separate flathead limit)." Every overlay on this water body is listed in full above.
- Do I need a fishing license to fish Mississippi River Pool 16?
- Yes. Mississippi River Pool 16 is in Iowa, so a valid Iowa fishing license is required just as it is anywhere else in the state, issued by Iowa Department of Natural Resources (Iowa DNR). The special regulations on this page change the bag, size, slot, or gear rules for Mississippi River Pool 16; they do not waive the license requirement. Free-fishing days and youth exemptions follow the statewide Iowa rules.
- Do Mississippi River Pool 16's special rules replace Iowa's statewide limits?
- Only where they conflict. Iowa's statewide 2026 regulations apply on Mississippi River Pool 16 by default; the overlays above replace the matching statewide rule for the species or gear they name, while everything not specifically overridden still follows the statewide rule. When a water-body rule and the statewide rule disagree, the water-body rule wins.
