Mahwah River facts for kids
The Mahwah River is a small river that flows into the Ramapo River. It runs through parts of Rockland County, New York State and Bergen County, New Jersey. This river is about 11 miles (18 kilometers) long.
It starts near a place called Ladentown, New York. The river then flows south and ends in the Ramapo River in Mahwah, New Jersey. This is close to the New York-New Jersey border. The Mahwah River follows a special geologic fault line. It also runs along the edge of Harriman State Park. Many small streams from the Ramapo Mountains join the river as it flows. Much of its path runs next to U.S. Route 202.
Where the Mahwah River Flows
The Mahwah River starts near Lime Kiln Mountain. It first goes through the Ladentown Swamp. This swamp is a large wetland area. It is also an important aquifer, which means it holds a lot of underground water.
As the river flows south, it passes through different areas. Sometimes, its path is blocked by dams. These dams create small ponds and lakes. In other places, the river flows through forests. Here, it looks very natural and untouched.
About 4.5 miles (7.2 kilometers) from its start, the river goes under Sky Meadow Lane. Soon after, it enters a part where Harriman State Park is on both sides. The river then flows through Kakiat County Park. After that, it goes under Route 202.
Further south, the river flows into Antrim Lake. Right after the lake, it goes under the New York State Thruway. It then flows through Suffern. Finally, it crosses the state line into New Jersey and joins the Ramapo River in Mahwah.
Animals Living in and Around the Mahwah River
The Mahwah River is home to many kinds of fish. You can find brook trout and brown trout here. There are also largemouth bass, pickerel, catfish, bluegills, suckers, and chubbs.
Many birds also live near the river. In the northern parts, you might see wood ducks. Mallards and Canada geese are common along the whole river. You might also spot muskrats and beavers in the water. Sometimes, an otter swims by too.
The forests and mountains around the river are full of wildlife. Look for large woodpeckers called pileated woodpeckers. Wild turkeys and whitetailed deer are also common. You might even see a black bear or a coyote in these areas.
Flooding Concerns Along the River
In a part of Suffern called Squires Gate, there have been problems with flooding. This happens when there is very heavy rainfall. Local leaders and people in the area are discussing how to fix this issue. They are trying to find the best way to stop the flooding.
