What Is the Public Trust?

Think of public parks and the beaches and waters of our Great Lakes. Who owns these public spaces and resources? The short answer is that you do, meaning you, the public.

This concept of public spaces and resources like water being owned and shared by the public is not a new one; in fact, it dates back 1500 years to the times of Roman emperor Justinian and has been a part of English common law and our U.S. democracy for centuries. Under Roman law, the public’s right to use common resources like the waters and surrounding shores was paramount. “By the law of nature these things are common to mankind, the air, running water, the sea, and consequently the shores of the sea.” Under the Magna Carta in 1215, the British Crown was prohibited from transferring the valuable coastal fisheries to private lords because the seabeds belonged to the people. This is what we now call the Public Trust Doctrine.

This legal concept has taken hold worldwide, protecting resources for the public from beaches (below the ordinary high-water mark line) to navigable waterways and harbors, to wetlands and wildlife, to tributary streams and groundwater. And this idea of protecting public places for public uses, such as navigation, commerce, fishing, boating, swimming, and other recreational purposes, makes sense. In fact, the right of each person, as a member of the public, although shared with others, is inalienable, in the same way as each person is protected in their ownership and use of private property and right to breathe the air.

Making Sense of the Public Trust Doctrine

The Public Trust Doctrine holds that certain natural resources like navigable waters are preserved in perpetuity for public use and enjoyment. Applying a banking analogy, the state serves as a trustee to maintain the trust or common resources for the benefit of current and future generations who are the beneficiaries. Just as private trustees are judicially accountable to their beneficiaries, so too are state trustees in managing public trust properties.

In addition, any private, public or commercial existing or proposed use, diversion or discharge cannot harm the waters of the Great Lakes by materially reducing the flow, changing the levels, or polluting the waters of the Great Lakes Basin. Furthermore, those who seek to use, continue to divert or alter the waters of the Great Lakes Basin, have the burden of proof to show they will not impair, pollute or harm the water. If they do not satisfy this burden of proof, the proposed action is not permitted under the public trust.

Lastly, under the public trust, the waters of the Great Lakes Basin can never be controlled by or transferred to private interests for private purposes or gain. Our rights to use the water of the Great Lakes Basin cannot be alienated or subordinated by our governments to special private interests; this means that all reasonable private use and public uses may be accommodated so long as the public trust waters and ecosystem are not harmed and paramount public right to public uses are not subordinated or impaired. Because many citizens are not aware that the public trust doctrine is part of their bundle of rights in our democracy, many of our leaders and big business are ignoring and violating these principles.

    Hello, I hope working together to unite the people in how we depend on our trust with all levels of government. Transparency is vital when it comes to our water, air and land. Can we work together? Please visit OurPublicTrust.com and let me know?

    United we the people are strong, divided we make little headway in TRANSPARENCY from any government around the world.


    I live in York Region, Ontario Canada, while we do not have water shortages what we have is very irresponsible Municipal Government which allows fill importation sites in or adjacent to groundwater recharge areas. I would like help and any information you can provide on mitigating this situation before the upland fill sites contaminate a small farm property I manage for a disabled trust beneficiary and his children in order to ensure clean water is available for them and for future generations.

    Any help is appreciated
