For real estate professionals in the Bay State, understanding how property lines interact with bodies of water is not just a coastal concern—it is a statewide necessity. From the shores of Cape Cod to the banks of the Charles River and the numerous "Great Ponds" scattered inland, water rights are a heavily tested topic on the state licensing exam. If you are currently mapping out your study plan, integrating this topic with our Complete Massachusetts Exam Guide will give you a significant advantage on test day.
In this guide, we will break down the essential concepts of water rights, distinguish between riparian and littoral laws, and dive into the unique historical statutes that govern Massachusetts waterways.
Understanding the Basics: Riparian vs. Littoral Rights
Real estate candidates must clearly distinguish between the two primary categories of water rights. The easiest way to remember the difference is by the type of water body adjacent to the property.
Riparian Rights (Rivers and Streams)
Riparian rights apply to properties bordering flowing bodies of water, such as rivers, streams, and brooks. The extent of a property owner's rights depends on whether the waterway is classified as navigable or non-navigable.
- Non-Navigable Waterways: If a river or stream cannot support commercial boat traffic, it is considered non-navigable. In Massachusetts, an owner of property bordering a non-navigable stream typically owns the land beneath the water up to the exact midpoint (the center thread) of the waterway.
- Navigable Waterways: If the river is large enough for commercial traffic, it is navigable. In this case, the property owner only owns the land up to the accretion line (the water's edge). The state owns the water and the land beneath it to ensure public use for transportation and commerce.
Practical Example: If your client buys a home on a small, trickling brook in the Berkshires (non-navigable), their property line extends to the middle of the brook. If they buy on the navigable Merrimack River, their property line ends at the riverbank.
Littoral Rights (Lakes and Oceans)
Littoral rights apply to properties bordering stationary or tidal bodies of water, such as oceans, seas, and large lakes. Because Massachusetts has a vast coastline, littoral rights are frequently tested.
Generally, in most of the United States, a littoral property owner owns the land up to the mean high-water mark. However, Massachusetts has a unique historical exception to this rule, which we will explore below.
Massachusetts Specifics: The Colonial Ordinances of 1641-1647
To demonstrate genuine expertise in Massachusetts real estate law, you must understand the Colonial Ordinances of 1641-1647. This historic law makes Massachusetts (along with Maine) unique compared to the rest of the country regarding coastal property rights.
Under these ordinances, private property ownership on the coast extends down to the low-water mark (or 100 rods from the high-water mark, whichever is less), rather than stopping at the high-water mark. However, this private ownership is subject to the Public Trust Doctrine.
The state reserves an easement over the area between the high and low-water marks (the intertidal zone) for the public's right to engage in three specific activities:
- Fishing: Catching fish or digging for shellfish.
- Fowling: Hunting waterfowl.
- Navigating: Passing freely in boats or vessels.
Exam Tip: Strolling, sunbathing, or setting up beach chairs are not included in these protected public rights. Therefore, a private beach owner in Massachusetts can legally ask someone to leave if they are just walking along the tidal flats, provided they are not fishing, fowling, or navigating.
Chapter 91: The Massachusetts Public Waterfront Act
Often referred to as the oldest waterway protection law in the nation, Massachusetts General Laws Chapter 91 was established in 1866 to protect the public's interest in waterways.
Chapter 91 regulates activities on both coastal and inland waterways, ensuring that private development does not unreasonably interfere with public rights. It applies to:
- Tidelands (both flowed and filled).
- Navigable rivers and streams.
- Great Ponds: In Massachusetts, a "Great Pond" is defined as any natural pond containing more than 10 acres in its natural state. The public has the right to access Great Ponds for fishing, fowling, and boating.
If a property owner wants to build a dock, pier, or retaining wall in these protected areas, they must obtain a Chapter 91 license from the Department of Environmental Protection (MassDEP).

Natural Changes to Land and Water Boundaries
Water is a dynamic force, and the physical changes it causes to land can alter property lines. The Massachusetts exam will test your knowledge of these four terms:
- Accretion: The gradual and imperceptible addition of land by the depositing of soil (alluvion) by water. Result: The property owner gains land.
- Erosion: The gradual wearing away of land by water or wind. Result: The property owner loses land.
- Avulsion: The sudden, violent tearing away of land (e.g., a hurricane washing away a chunk of coastline). Result: The property lines do not change; the owner still owns the submerged land and has the right to reclaim it.
- Reliction: The gradual receding of water, leaving dry land behind. Result: The property owner gains the newly exposed land.
Navigating Water Rights in Transactions
When dealing with waterfront properties, real estate agents must be meticulous. Water rights are considered appurtenant, meaning they are attached to the land and transfer automatically to the new owner upon sale unless explicitly excluded.
Ensuring that docks and piers are properly permitted under Chapter 91 is a critical step in the title search process. An unpermitted dock can hold up a sale or result in hefty fines for the buyer. To understand how these rights are formally conveyed, review our guide on Massachusetts Deeds and Title Transfer.
Furthermore, agents representing buyers of waterfront property should ensure that protective contingencies are written into the purchase agreement. Allowing the buyer time to verify Chapter 91 compliance, flood zone status, and wetland protections is vital. Brush up on how to draft these protections in our Massachusetts Contract Essentials and Elements article.

Frequently Asked Questions (FAQs)
What is the easiest way to remember the difference between riparian and littoral rights?
Think of the first letters: Riparian is for Rivers (flowing water). Littoral is for Lakes and oceans (stationary water).
Can the public walk on a privately owned beach in Massachusetts?
In Massachusetts, private ownership extends to the low-water mark. The public only has the right to access the area between the high and low-water marks for "fishing, fowling, and navigating." General recreation, such as walking or sunbathing, is technically trespassing without the owner's permission, though enforcement varies.
What is considered a "Great Pond" in Massachusetts?
A Great Pond is defined by state law as any natural pond that is 10 acres or larger in its natural state. The public retains the right to access Great Ponds for fishing and boating, and the state owns the land beneath the water.
If a storm suddenly washes away 10 feet of my client's waterfront property, do they lose ownership of that land?
No. This is an example of avulsion—a sudden and violent loss of land. Because the change was sudden, the property boundaries remain the same, and the owner legally has the right to reclaim or refill the lost land, subject to environmental regulations.
Do water rights need to be explicitly mentioned in a deed to transfer to the buyer?
No. Water rights are appurtenant to the land. This means they are inherently tied to the property and will automatically transfer to the new owner during a sale unless the seller explicitly reserves them in the deed.
