You’ve probably never heard of Lake Mary Jane. Most people haven't, even those who live in the sprawl of Central Florida. Tucked away in the southeastern corner of Orange County, near the burgeoning "Medical City" of Lake Nona, it looks like just another pretty Florida lake. It’s quiet. Moss-draped cypress trees line the shore. Pontoon boats drift slowly through the tea-colored water.
But Lake Mary Jane FL isn't just a place to catch largemouth bass anymore. It is the literal face of a revolutionary legal movement.
A few years ago, this lake became the first "nature-based" plaintiff in a U.S. lawsuit. Yes, the lake sued a developer. While that sounds like something out of a sci-fi novel, it’s a very real, very gritty part of Florida’s battle between breakneck development and environmental survival. If you're looking for the typical Disney-adjacent vacation spot, keep driving. But if you want to understand the soul of the "real" Florida—and the massive legal storm brewing over its waters—this is where you start.
The Lake That Sued for Its Life
In 2021, Lake Mary Jane became a household name in legal circles. The case was Lake Mary Jane et al. v. Noah Valenstein. The lake itself, along with Marsh Parsley, Crosby Island Marsh, and Lake Hart, filed a lawsuit to stop a 1,900-acre housing development.
How does a body of water sue? Under a legal theory called the "Rights of Nature."
Voters in Orange County had overwhelmingly passed an amendment to their charter. It gave natural bodies of water the right to exist, to flow, and to be protected from pollution. It was a massive win for grassroots environmentalism. Honestly, it was kind of a shock to the system for local politicians. The lawsuit argued that the proposed "Beachline South" development would destroy wetlands and disrupt the natural flow of the water.
The courts eventually tossed the case. Why? Because the Florida Legislature stepped in and passed a law specifically banning local governments from granting "legal rights" to nature. They basically nuked the local ordinance from the state level. It was a classic Florida power struggle. Even though the lake "lost" in court, the movement hasn't stopped. It turned Lake Mary Jane into a symbol for every environmentalist in the country.

What It’s Actually Like at Moss Park
If you want to experience Lake Mary Jane FL today, you head to Moss Park. It’s a 1,500-acre county park that sits right on the shore. It feels like a time machine.
The water is stained dark by tannins from the trees. It’s "blackwater," but it’s remarkably clean. You can rent a kayak and paddle out into the middle where the silence is heavy. It's different from the man-made lakes in the middle of Orlando’s suburbs. This is part of the Split Oak Forest ecosystem. You’ll see sandhill cranes. You might see a gopher tortoise. You will definitely see an alligator, likely sunning itself on a log near the reeds.
Don't swim outside the designated areas. Seriously.
The park has a massive camping area that stays packed during the winter months when the "snowbirds" come down. It's one of the few places left where you can see the stars without the orange glow of the Orlando city lights washing everything out. The wind through the pine trees makes this low, humming sound that you just don't get in the city.
The Split Oak Controversy
You can't talk about Lake Mary Jane without talking about Split Oak Forest. They are physically and politically linked.
For years, there’s been a push to run a toll road extension—the Osceola Parkway Extension—right through a portion of the Split Oak Forest Wildlife and Environmental Area. This forest acts as a critical upland buffer for Lake Mary Jane. Environmentalists argue that if you pave over the forest, the lake's health will tank.

It’s a mess of bureaucracy. You have the Central Florida Expressway Authority (CFX) on one side and a group of "Friends of Split Oak" on the other. In 2024 and 2025, the legal battles intensified over whether "protected" land can actually be traded away for development.
When you visit, you’ll see the "Save Split Oak" signs. It’s not just a local hobby; it’s a war for the future of the region's hydrology. The people who live around Lake Mary Jane aren't your typical activists. Many are long-time locals who have watched the orange groves disappear and don't want the water to go next.
Fishing and Wildlife Facts
- Largemouth Bass: This is the big draw. The lake is known for decent-sized bass, though they can be finicky when the water level drops.
- Birding: It’s a stop on the Great Florida Birding Trail. Look for Ospreys, Bald Eagles, and Wood Storks.
- The Island: There is a small island in the lake that serves as a rookery. Stay back to avoid disturbing the nests.
The Practical Side: Getting There and Staying
Lake Mary Jane is roughly 20 to 30 minutes from Orlando International Airport (MCO). It’s incredibly close to the urban core but feels like it’s 100 miles away.
If you're planning a visit, Moss Park is the primary entry point.
Address: 12901 Moss Park Rd, Orlando, FL 32832.
The gate fee is usually just a few dollars. It’s cheap. It’s accessible. But it gets crowded on weekends. If you want the "ethereal" experience of the lake, show up at 8:00 AM on a Tuesday. The fog rolls off the water, and you’ll have the whole place to yourself.
Where to Eat Nearby
There isn't much right on the water. That’s the point.
However, just a 10-minute drive away is Lake Nona. It’s the total opposite of Lake Mary Jane. It’s ultra-modern, full of "smart" technology and high-end restaurants like Canvas Restaurant & Market. It’s a jarring contrast—one minute you’re in a prehistoric swamp, the next you’re in a sleek, glass-and-steel neighborhood.

Why This Lake Still Matters
Some people think the Rights of Nature movement died when the lawsuit was dismissed. They’re wrong.
Lake Mary Jane FL proved that people are desperate to protect what’s left of Florida’s interior. It showed that "personhood" for nature isn't just a fringe idea; it’s a legal tool that nearly worked. The lake has become a case study in law schools. It’s a point of pride for the local community.
As Florida grows—and it’s growing at a rate of about 1,000 people moving here every single day—places like this become more than just recreation spots. They become the lungs of the state.
Actionable Steps for Your Visit
If you want to support or explore Lake Mary Jane, here is what you actually need to do.
- Check the Water Levels: During dry spells, the boat ramps at Moss Park can get tricky. Check the Orange County park alerts before you haul a heavy boat down there.
- Volunteer with Friends of Split Oak: If the legal battle interests you, they are the main boots-on-the-ground group. They host guided hikes that explain the connection between the forest and the lake's water quality.
- Use Non-Motorized Craft: To really see the "Rights of Nature" side of the lake, take a canoe or paddleboard. The shallow edges where the lilies grow are where the real life happens—turtles, small fish, and rare plants.
- Stay Informed on the Toll Road: The Osceola Parkway Extension project is constantly in flux. If you live in the area, attending the CFX board meetings is the only way to stay ahead of how development will impact the lake’s eastern shore.
- Respect the Buffer: If you're hiking the trails around the lake, stay on the marked paths. The soil around the lake is part of a delicate seepage slope system that filters runoff before it hits the water.
Lake Mary Jane isn't a theme park. It doesn't have a mascot. It just has water, trees, and a very long, very complicated legal history. Whether you go there to fish or to witness a piece of environmental history, you'll leave understanding why people fought so hard to give a lake its own voice.

This lake represents the friction point between the old Florida and the new. It's worth the drive just to see which side is winning today.
