Just came across this:
Not sure how old this is. The link to the website is dead.Fishing Legal in River Despite Adjacent Private Land
The Chicago Whitewater Association (http://www.izarea.org/cwa) reports that a man was ticketed for fishing on a section of river running through private property. Although the absent property owner had not complained about the activity, a Department of Natural Resources official ticketed the man anyway.
The fisherman took his complaint to court, where the judge found him not guilty because the state had not shown beyond a reasonable doubt that he had violated any law. His defense was based on sections 18 and 26 of the Illinois statutes protecting the right of the people to have access to all navigable waterways, regardless of the ownership of the adjoining banks.
Tracked down sections 18 and 26 of the Illinois Statutes. Here are parts that pertain. I ain't no lawyer though . . .
(615 ILCS 5/18) (from Ch. 19, par. 65)
Wherever the terms public waters or public bodies of water are used or referred to in this Act, they mean all open public streams and lakes capable of being navigated by water craft, in whole or in part, for commercial uses and purposes, and all lakes, rivers, and streams which in their natural condition were capable of being improved and made navigable, or that are connected with or discharged their waters into navigable lakes or rivers within, or upon the borders of the State of Illinois, together with all bayous, sloughs, backwaters, and submerged lands that are open to the main channel or body of water and directly accessible thereto. Nothing herein contained applies to a harbor under the jurisdiction and control of a park district, nor to any existing yacht club facilities, improvements thereon and replacements thereof whether in the same or a new location. Nothing herein contained applies to the location of any harbor under the jurisdiction and control of any city or village of less than 500,000 population.
Now go back and read the long Public Ownership of Rivers post.(615 ILCS 5/26) (from Ch. 19, par. 73)
Sec. 26. The Department of Natural Resources shall, for the purpose of protecting the rights and interests of the State of Illinois, or the citizens of the State of Illinois, have full and complete jurisdiction of every public body of water in the State of Illinois, subject only to the paramount authority of the Government of the United States with reference to the navigation of such stream or streams, and the laws of Illinois, but nothing in this Act contained shall be construed or held to be any impairment whatsoever of the rights of the citizens of the State of Illinois to fully and in a proper manner, enjoy the use of any and all of the public waters of the State of Illinois, and the jurisdiction of the Department of Natural Resources shall be deemed to be for the purpose of protecting the rights of the people of the State in the full and free enjoyment of all such bodies of water, and for the purpose of preventing unlawful and improper encroachment upon the same, or impairment of the rights of the people with reference thereto, and every proper use which the people may make of the public rivers and streams and lakes of the State of Illinois shall be aided, assisted, encouraged and protected by the Department of Natural Resources.

As I've been saying for years, I go where ever I want when it comes to rivers and streams.
Seems to be the law.
Oh hell, just go read the whole thing. I know I will be.
