If you’ve ever driven down Highway 94 in Hyde County, you know the feeling. One minute you're surrounded by endless rows of corn and soybeans, and the next, the world just... opens up. You’re suddenly on a thin ribbon of asphalt cutting through 40,000 acres of water that looks more like a shimmering mirage than a lake. This is Lake Mattamuskeet North Carolina. It’s the largest natural lake in the state, but honestly, it’s basically a giant, shallow saucer.
Most people don't realize that if you stepped out of your boat in the middle of the lake, you'd probably only be waist-deep. On average, it’s only about two feet deep.
There’s a strange, quiet energy here. It’s a place where the wind can whip up a "tide" that pushes water miles across the flat landscape, and where the sound of 30,000 Tundra Swans taking flight at once sounds like a low-frequency freight train. But beneath that scenic surface, there’s a real fight happening. The lake is sick, and the story of how it got this way—and why it might never be the same—is a lot more complicated than the brochures at the visitor center let on.
The Weird History of a Lake That Shouldn't Be
Nobody actually knows how Lake Mattamuskeet formed.
Some folks will tell you it was a massive meteorite shower that pockmarked the Carolina coast. Others swear it was a "peat fire"—a slow-burning underground blaze that scorched the earth so deep it created a basin. Scientists are still arguing about it. Whatever the cause, the Mattamuskeet tribe of the Algonquin Indians called it "dry dust," which is a bit ironic for a lake, but it points to how often this area has fluctuated between marsh and open water.
The Great Drainage Failure
In the early 1900s, people got the wild idea that the lakebed was too fertile to leave underwater. They wanted to turn it into the "Holland of the South."

They built a massive pumping station—which still stands today as the iconic Mattamuskeet Lodge—and literally pumped the lake dry. Multiple times. They built a town called New Holland. They planted crops. They even had a post office. But the lake didn't want to stay dry.
- 1914: Large scale drainage starts.
- 1925: A New York philanthropist tries again, and for about six years, it actually works.
- 1932: Mother Nature wins. Heavy rains and pests bankrupt the project.
- 1934: The feds buy it, and it becomes the Mattamuskeet National Wildlife Refuge.
That old pumping station? It’s a beautiful, eerie brick building with a smokestack that was later turned into an observation tower. It’s been closed for years because of structural issues, but it remains the symbol of the lake’s refusal to be tamed.
Why Lake Mattamuskeet North Carolina is Facing a Crisis
If you visited 20 years ago, the water was clear. You could see the bottom. Lush beds of wild celery and muskgrass covered the lake floor. Today? It looks like chocolate milk.
Basically, the lake has hit a tipping point.
The underwater grasses (SAV, or submerged aquatic vegetation) are almost entirely gone. Without those grasses to hold the sediment down, the wind stirs up the mud, making the water so cloudy that sunlight can’t reach the bottom to grow new grass. It’s a vicious cycle.

Then you’ve got the carp. Millions of pounds of invasive common carp are "rooting" around the bottom, further muddying the water and eating what little vegetation is left. Experts at North Carolina State University estimated there were about 4.4 million pounds of carp in there recently. That's about 110 pounds of fish for every single acre of water.
The Runoff Problem
Hyde County is pancake-flat. Because of that, all the nutrients from surrounding farms—nitrogen and phosphorus—have nowhere to go but into the lake. This feeds massive algae blooms. In 2016, the lake was officially listed as "impaired." It’s not just a "nature" problem; it’s an ecological emergency for the Atlantic Flyway.
What You Can Actually Do There Right Now
Despite the water quality issues, Lake Mattamuskeet is still a bucket-list spot for birders and photographers.
If you're planning a trip, timing is everything. Don't show up in July expecting to see much besides mosquitoes the size of small birds. You want the winter. Between November and February, the refuge is home to one of the largest concentrations of Tundra Swans and Canada Geese on the East Coast.
Best Spots for Wildlife Viewing
- The Highway 94 Causeway: This is the easiest way to see birds. You can pull off at designated areas and just watch. The swans love to congregate near the bridge.
- Wildlife Drive: A 3-mile loop that gets you off the main road and closer to the impoundments where ducks like Pintails and Gadwalls hang out.
- The Lodge Grounds: Even though you can't go inside the Mattamuskeet Lodge, the area around it is great for seeing Bald Eagles and Ospreys.
Fishing and Crabbing
People still fish here, though the Largemouth Bass population has seen better days because of the loss of grass. Most locals stick to the canals for white perch, crappie, and catfish.

But the real draw? Blue crabs.
Crabbing at the water control structures along the causeway is a local pastime. The crabs here are famously large. Just make sure you check the current regulations, as the lake is closed to boating from November 1st through the end of February to give the birds some peace.
The Restoration Fight: Can We Fix It?
There’s a $1 million plan in place to remove the carp, but it’s been slow going. The U.S. Fish and Wildlife Service hired contractors to net them, but as of 2025, they hadn't hit their targets.
There's also a big debate about "active drainage." Some residents want to see the lake levels lowered mechanically to let the sun hit the bottom and jumpstart the grass growth. Others worry that pumping water out just sends the pollution somewhere else, like the Pamlico Sound.
It’s a mess, honestly. There is no easy fix when you're dealing with a 40,000-acre lake that's only two feet deep.
Making the Most of Your Visit: Actionable Steps
If you’re heading to Lake Mattamuskeet North Carolina, here is how to do it right:
- Bring Optics: You need a decent pair of binoculars or a spotting scope. Most of the birds stay a few hundred yards out from the road.
- Check the Gate: If you're crabbing, remember that the "tide" gates are where the action is. When the water is moving, the crabs are biting.
- Download the Map: Cell service in Hyde County is notoriously spotty. Download the Mattamuskeet NWR map from the FWS website before you leave Swan Quarter.
- Visit the "New Holland" Site: Look for the old ruins of the town near the lodge to get a sense of just how much effort went into trying to drain this place.
- Watch the Sunset: Because the lake is so shallow and wide, the sunsets are some of the most dramatic in the South. The causeway is the place to be at dusk.
Support local efforts by visiting the Hyde County Visitor Center or checking in with the North Carolina Coastal Federation, who are leading the charge on the watershed restoration plan. This lake is a survivor, but it needs a lot of help to get its "dry dust" magic back.
