Iowa fishing rules
License, gear, and the statewide limits Iowa DNR publishes for major species. Water-specific rules replace these numbers. Last checked October 2026.
License
- Who needs one
- Iowa residents and nonresidents 16 and older must have a valid fishing license on their person while fishing and must have paid all applicable fees. Residents and nonresidents under 16 do not need a fishing license. A trout fee is required to fish for or possess trout if a fishing license is required. Children under 16 may fish for trout without the fee only when they fish with a licensed adult who has paid the trout fee and the group keeps one person’s daily limit of five trout. A child under 16 who pays the trout fee may keep a separate limit of five.
- Residents
- A resident license requires that Iowa has been the person’s principal residence for at least 90 consecutive days immediately before applying, with an Iowa driver’s license or non-operator identification, unless another listed test applies. Living in Iowa only to hunt, fish, or trap does not qualify. Full-time students, a nonresident under 18 whose parent is an Iowa resident, and qualifying military members have separate resident paths in the 2026 booklet. Resident annual fishing is $22, a 7-day license is $15.50, a 1-day license is $10.50, and the resident trout fee is $14.50. A third-line permit is $14. Landowners and tenants, and their children under 18, may fish without a license on their own land.
- Nonresidents
- Anyone who does not meet a resident test needs a nonresident license. The 2026 booklet lists nonresident annual fishing at $48, a 7-day license at $37.50, a 3-day license at $20.50, a 1-day license at $12, and the nonresident trout fee at $17.50. The third-line permit is $14 for nonresidents as well. Nonresidents under 16 do not need a fishing license but may need the trout fee under the same youth rule as residents. Someone who previously bought Iowa licenses as a nonresident must file a resident application before a vendor can sell a resident license.
- Free fishing days
- Free fishing days are June 5, 6, and 7, 2026, and they are for Iowa residents only. Residents may fish without a license or trout fee. All other regulations remain in place, including lure restrictions, length limits, and possession limits.
Seasons and closures
Continuous seasons and closures
Black bass, catfish, trout, northern pike, bluegill, crappie, and yellow perch are open continuously on the waters the booklet marks continuous. Walleye are continuous except the Dickinson County lakes listed above. Muskellunge are continuous except West Okoboji, East Okoboji, Spirit, and the Iowa-Minnesota boundary lakes, which are open May 21 through November 30. Threatened and endangered species, including lake sturgeon and pallid sturgeon, are closed. Once a daily bag is reached, fishing for that species may continue if every extra fish is released immediately. Sorting or replacing a fish already in possession is prohibited, except participants in DNR-permitted black bass and catfish tournaments.
Paddlefish and turtles
Interior waters are open continuously for paddlefish except snagging closures. The Mississippi paddlefish season is March 1 through April 15 in the dam reaches, with a 33-inch maximum. The Missouri and Big Sioux season is February 1 through April 30, with a 35- to 45-inch protected slot and a special paddlefish license and tag. Common snapping turtles are open continuously. Spiny softshell, smooth softshell, and painted turtles are open July 16, 2026 through May 14, 2027. Nonresidents may take those turtle species only from the Missouri, Mississippi, and Big Sioux, and may not take other turtles or crayfish elsewhere in the state.
Legal gear
Hooks and barbless rules
The 2026 booklet does not state a statewide barbless-hook rule. Hook-and-line fishing is limited to two lines and two hooks on each line while still fishing or trolling. Fly fishing is limited to two flies on one line. Trolling and bait casting are limited to two trolling spoons or artificial baits on one line. One hook means a single, double, or treble hook, and every hook on one artificial bait counts as one hook. An Alabama or umbrella rig is not treated as one artificial bait. A valid third-line permit adds one more line. Lines with hooks may not be left out of sight. For paddlefish snagging, hooks may not be larger than a 5/0 treble or longer than 1 1/4 inches when two points are placed on a ruler.
Rods per angler
Two lines is the default. The third-line permit allows a third line or a third jug. Jug fishing is limited to two jugs, or two hooks on each jug, and the jugs must stay in sight. The combinations are one pole and one jug, or two jugs and no pole, unless the third-line permit is held. On inland ice, an angler may use one tip-up and one line, or two tip-ups and no extra line, plus a third device with the permit. On the Mississippi, Missouri, and Big Sioux rivers and their connected backwaters, up to three tip-ups may be used, with no more than three hooks total, and those tip-ups are in addition to two lines with no more than two hooks per line. Tip-ups on those rivers must be tagged and may not be used within 300 feet of a dam or spillway.
Nets
A landing net or gaff may be used to help land a legally hooked fish. A gaff or other penetrating device may not be used to land a snagged paddlefish. Grab hooks, snag hooks, nets, seines, and traps may not be used to take fish, except the bait-collection gear and the turtle traps described in the booklet. For personal bait, a minnow trap may not be more than 3 feet long and must be tagged, a minnow dip net may not be larger than 4 feet in diameter, a cast net may not be larger than 10 feet in diameter, and a minnow seine may not be longer than 20 feet. Seines for personal bait must have mesh not smaller than one-quarter inch bar measure. Commercial bait harvest needs a bait dealer license.
Snagging
Snagging, bowfishing, and spearing may be used for the rough fish listed in the booklet, including common carp, bighead and silver carp, buffalo, carpsuckers, redhorse, drum, gar, bowfin, gizzard shad, and goldfish, and for paddlefish where that season is open. Game fish not hooked in the mouth must be returned immediately, except paddlefish. Snagging is closed in the dam and bridge sections listed in the booklet, including the reaches below Saylorville, Coralville, Rathbun, and the other named dams. On the Mississippi, paddlefish snagging is limited to 500 yards below navigation dams from March 1 through April 15. On the Missouri and Big Sioux, snagging hours for that fishery are sunrise to sunset in the open season.
Spearing and bow
Nongame fish and frogs may be taken by bow and arrow and spear with a valid sport fishing license. Bowfishing and spearing are allowed on public lakes, reservoirs, and rivers, on private ponds with permission, and on the border waters described in the booklet. State parks, federal refuges, and some city and county lakes add their own rules. The same hook-size cap used for snagging applies when bowfishing, spearing, and snagging are discussed together in the methods section. Several inlets and outlets, including Clear Lake and Lost Island Lake, are closed to snagging, bow and arrow, and spearing.
Bait and live transport
Bait includes minnows, green sunfish, orangespotted sunfish, live or dead gizzard shad, frogs, crayfish, salamanders, and mussels, but live gizzard shad may not be possessed at any lake. Game fish caught legally on hook and line may be used as bait. Live bait moved from one area to another must be in clean water. Dumping bait in Iowa lakes, rivers, or streams is illegal. Before leaving a water, bait-bucket water must be exchanged for tap or bottled water if the bait is kept. Live fish other than hooked bait may not be stocked into public waters without the director’s permission. Crayfish taken from Storm Lake for personal use may be used only in Storm Lake and may not be transported live from that lake. Live mussels may be taken only from the Mississippi River and its connected backwaters.
Bag and size limits
These are the statewide or default limits. A named lake, river, or marine area can replace every figure below.
