Follow Illinois River for flow alerts

Pick one of its USGS gauges and hear from us when the flow moves into or out of its usual range for the date, or crosses a flow you set. We check the public USGS reading every 2 hours and email only when it crosses, at most once every 6 hours. Flow alone is not a fishing forecast or a safety call.

Follow this water

Signed in: one step. Otherwise we email a confirmation link first. Every alert has one-click links to stop it.

Restrooms within 2 miles of Illinois River in a straight line, nearest first, with what anglers found when they went. The map says a restroom is there, not whether it is clean or open today.

No restroom mapped within 2 mi yet — add one you know.

Campgrounds, fishing access sites and boat ramps often have one that isn't on the map yet.

Regulations

About this

Seasons, limits, special regulations and closures for each reach are on the agency pages below. Read them before you go.

3 official designations

Each comes from the agency's own published list; where the list names a reach it is quoted. A designation applies to the listed reach, not necessarily the whole water. Listed in the finder under trout.

Public land along it

About this

Areas the Protected Areas Database of the United States (PAD-US), public access (U.S. Geological Survey, Gap Analysis Project, read 2026-11-05) lists as owned or held in easement and open to the public, crossed by the mapped channel. Boundaries are mapped, not surveyed. Nothing on this page grants or implies access: check the agency map, posted signs and landowner permission before you fish.

Fish these abroad

About this

Matched on the fish the agencies list for both waters first, then the same water type, an official designation or flagship listing on both, and a similar mapped size where USGS hydrography covers both.

At most two waters per country. A shared fish is a listing, not a promise: presence varies by reach and season.
