Iowa

Mississippi River between Illinois and Iowa

Officers of Illinois and Iowa will recognize and accept valid sport fishing licenses of either state when legally possessed and used by hook-and-line sport fishermen on the Mississippi River proper forming a common boundary between Illinois and Iowa, including its backwater lakes and sloughs contiguous with the flow of waters in the main channel; provided that you do not fish from or attach any device or equipment to the main bank of the Mississippi under the jurisdiction of the state where you are not licensed to fish. You can not fish in any tributaries of the opposite state. You must conform to the regulations of the state in which you are fishing unless the regulations of your licensing state are more restrictive, then you must conform with the more restrictive regulations. The center of the navigation channel is the boundary between Illinois and Iowa. Tournaments fishing Iowa waters must have an Iowa fishing tournament permit, even if launching from the Illinois side of the river.

Missouri

Mississippi River between Illinois and Missouri

Officers of Illinois and Missouri will recognize and accept valid sport fishing licenses of either state when legally possessed and used in the Mississippi River and its backwaters within the boundary of Missouri adjacent to the state of Illinois. Persons licensed in only one state may also fish in the other state’s portion of any oxbow lakes through which the IllinoisMissouri boundary passes, and may fish from or attach any device or equipment to land under the jurisdiction of the other state. Persons licensed in only one state may not fish in tributaries of the Mississippi in the other state. Sport fishermen shall comply with the regulations of the state in whose waters they are fishing unless the regulations of their licensing state are more restrictive, then must comply with the more restrictive regulations. The center of the navigation channel is considered the boundary between Illinois and Missouri, except in situations where it is clearly shown to be elsewhere.

Kentucky

Ohio River between Illinois and Kentucky

Each state will recognize the sport fishing licenses and appropriate permits of the other state on the main stem and from the banks of the Ohio River, excluding embayments and tributaries where the Ohio River forms the state boundary. Embayments and tributaries shall be defined as a straight line between opposite points where the tributary or embayment connects with the main body of the Ohio River. The fishing regulations adopted by the state issuing a sport fishing license apply to the licenses when fishing each state’s respective waters, except that, all fishermen shall conform with the regulations of the state in which they are fishing, unless the regulations of the fishermen’s licensing state are more restrictive, then the fishermen must conform with the more restrictive regulations. The regulations of the state where the sport fishing is occurring apply, if the licensee is fishing from the bank. Wildlife law enforcement officials of either state shall have the right to inspect the licenses, harvest limits, creel limits, and equipment of any person on the Ohio River subject to the laws of either state. Officers of Illinois and Kentucky will recognize and accept valid sport fishing licenses of either state when legally possessed and used on the main stem of the Ohio River, excluding embayments and tributaries.

Wisconsin

The 2026 digest prints no Illinois-Wisconsin boundary-water agreement (Wisconsin borders Illinois on land and Lake Michigan shoreline only); the license section says non-residents licensed in a bordering state may fish the Illinois side of rivers adjoining that state.

Boundary river questions for Illinois

Can an Iowa angler fish the Illinois side of the Mississippi?

Yes. Illinois and Iowa officers accept either state’s license on the Mississippi main channel and its contiguous backwaters, under the conditions printed in the digest.

What about Missouri licenses on the Mississippi?

The digest prints a separate Illinois and Missouri agreement for the river where it forms their common boundary.

Does a Kentucky license work on the Ohio River?

Yes, on the main stem and from the banks, excluding embayments and tributaries; the issuing state’s rules apply in its own waters.

Can an Indiana angler fish the Wabash in Illinois?

Yes, within the natural and ordinary river banks; not in Illinois tributaries, bayous or backwaters.

Is there an agreement with Wisconsin?

No. The 2026 digest prints no Illinois and Wisconsin boundary-water agreement.

Which limits apply on a boundary river?

Those of the state in which you are fishing, per the agreements; site-specific entries for the river still apply.

Where are the river pages?

The Mississippi, Ohio and Wabash pages list ramps, pools and gauges along the Illinois shore.
