9 Michigan Lake Access Rules Property Owners Get Wrong

Michigan’s Great Lakes shoreline runs 3,288 miles, with four lakes’ worth of coastline touching one state.

But owning a piece of it comes with more fine print than many buyers expect.

These are the Michigan lake access rules that catch property owners off guard.

Note: This is general information, not legal advice. Michigan’s lake access, riparian, and permitting rules vary by lake and are subject to change.

1. High-Water Mark Line

Michigan’s Great Lakes shoreline looks like it belongs entirely to whoever owns the house facing it.

It doesn’t.

In 2005, the Michigan Supreme Court ruled in Glass v. Goeckel that the public can walk the Great Lakes shoreline below the ordinary high-water mark, even where a private deed runs all the way to the water’s edge.

A homeowner can still order someone off the dry sand above that mark.

Below it, they can’t.

Michigan courts measure a Great Lakes trespass claim against that line, not the property survey.

2. Inland Lakes Flip the Rule

On Michigan’s thousands of inland lakes, ownership works by the opposite rule.

The riparian owner typically owns the lake bottom itself, running out toward the middle of the water in a pie-shaped wedge.

Exactly the opposite.

So on an inland lake, walking a private beach without permission is trespassing.

Some inland lake owners assume the public keeps the same Great Lakes walking right on their frontage.

They let hikers cross without a word, thinking Michigan extended that rule inland.

It never did. The owner has full authority to ask a hiker to leave.

A visitor who learned the Great Lakes rule at a cousin’s cottage on Lake Huron can walk straight into a dispute two counties over on a smaller lake.

3. Passing Through, Not Camping Out

Below the high-water mark, Michigan’s public-trust rule covers walking, not whatever else a beach day usually involves.

Michigan courts limited that right to passage along the shore, tied to the traditional public uses of fishing, hunting, and navigation.

It isn’t a license to set up a cooler, a volleyball net, or a blanket for the afternoon on someone’s private sand.

A property owner can still ask a group to move along if they’ve stopped and settled in below the mark.

Keep walking, and you stay within your rights under Michigan’s public-trust rule.

Stay put, and you don’t.

4. Not Every Dock Needs a Permit

Michigan doesn’t require a state permit for every dock that goes into the water.

A small, private, seasonal dock that goes in for the season and comes back out again is exempt from state review under Part 301 and Part 325 of the state’s water law.

A permanent dock doesn’t.

A poured launch ramp, a large commercial dock, or anything that stays in year-round needs a Minor Project permit from EGLE, regardless of who owns the shoreline under it.

Owners guess wrong in both directions, either assuming they need paperwork for a simple summer dock or assuming a permanent dock is none of the state’s business.

5. Ice Fishing Crosses Private Water

Bottomland owners on Michigan’s inland lakes often assume owning the lake floor means they can keep ice anglers off it.

It doesn’t work that way.

Michigan lets an ice angler cross onto the frozen water above someone else’s private lake bottom, as long as the lake itself is legally navigable.

The public’s right to fish, ice included, counts as an incident of navigation, and it reaches over privately owned submerged land the same way boat traffic does in summer.

The bottom belongs to the owner.

The fish don’t.

A licensed angler can still fish the ice above it, according to Michigan State University’s inland lakes program.

Blocking access from dry land is a separate question, and a property owner can still keep people from cutting across their yard to reach the shore.

6. Not Every Lake Is Public

A small Michigan lake that never shows up on a public-access map can strike its owner as automatically private.

Courts don’t look at maps to decide it.

Courts have set a two-part test for navigability: A lake needs both a navigable inlet and a navigable outlet before the public gets any right to boat or fish it.

In Bott v. Commission of Natural Resources, the Michigan Supreme Court let a landowner keep the public off a 35-acre lake entirely inside his property, even though the lake’s outlet fed straight into a larger, public lake next door.

The lake had no inlet of its own.

That gap decided the case.

A landlocked pond with a trickle running out and nothing running in can be entirely private under that same test.

No public right applies, even if a boater could glide right in from the lake next door.

Michigan’s Great Lakes shoreline alone runs 3,288 miles, but thousands of the state’s smaller lakes never show up on a public-access map at all.

7. Backlot Neighbors and Dock Rights

Subdivision plats, not modern deeds, start many of Michigan’s oldest lake-access disputes.

Many older lakefront developments set aside a narrow walkway, park strip, or road end for every lot owner’s use, including owners whose lots never touch the water.

In Thies v. Howland, the Michigan Supreme Court ruled that whether a “backlot” owner can install a dock and moor a boat at that access point depends entirely on the exact wording of the plat’s own dedication.

In that case, the backlot owners lost: The court found their subdivision’s dedication language, a simple public “walk,” too thin to include a permanent dock or mooring right.

It isn’t automatic.

A waterfront owner can’t block that use just because their house sits closest to the water, when the plat’s language does cover it.

They can still object if a backlot neighbor’s dock crowds their own or blocks their view of open water, since Michigan’s reasonable-use rule protects both sides.

8. No Permanent Mooring at Your Dock

A boat idling near your Michigan dock can look like trespassing on sight.

Many owners assume they can order it away immediately.

Michigan courts see it differently, at least for a little while.

Michigan courts recognize a boater’s right to pass briefly through the water off someone else’s dock.

That incident-of-navigation right, set out in the 1953 case Hall v. Wantz, covers coasting by or stopping briefly to fish, not settling in.

Drop a permanent mooring instead.

Leave a boat anchored there for days, and Michigan treats it as trespassing on the riparian owner’s bottomland instead of navigation.

A dock owner tired of a stranger’s pontoon parked off their beach every weekend has grounds to complain, not just an annoyance to shrug off.

9. Deed Isn’t Riparian Rights

Michigan splits a lake lot into two different things: The land, and the water rights attached to it.

Buying a parcel near a lake, even one that shares a driveway with a waterfront property, doesn’t automatically hand over riparian rights.

Those rights stay with the land that physically touches the water unless a deed expressly reserves or transfers them to the new, non-touching lot.

No touch, no rights.

A buyer who assumed “walking distance to the lake” meant the same water rights as the house next door can find out otherwise at closing, or worse, after.

Riparian rights and water access are legally distinct questions in Michigan, and a title search settles one of them, not both.
