The Delaware River is a big river. 

The Delaware River is a very big river. 
It starts in the mountains of New York. Two small streams join to make the main river. Then it flows south through many lands. It passes by New York, Pennsylvania, New Jersey, and Delaware.
Many people use the river. It gives clean water for people to drink. It also helps people travel on boats. 
Long ago, the Lenape people lived here. They called the river by their own names. Later, the river was named for a man named Thomas West.
The river ends at a large bay. It flows into the sea there. It is a very important part of the land.
The Delaware River is a major river in the Eastern United States. 
It starts in the Catskill Mountains of New York. Two branches rise there. These are the East Branch and the West Branch. They meet at a place called Hancock. From there, the river flows south. It forms borders for New York, Pennsylvania, New Jersey, and Delaware. 
The river is special because it is free-flowing. This means there are no dams on its main path. It flows into the Delaware Bay at the end. Many people rely on this water. It provides drinking water for 17 million people. Half of New York City gets its water from the river.
Long ago, the Lenape people lived along the banks. They had their own names for the river. Later, the river was named after Thomas West. He was an English nobleman. 
The river has seen big moments in history. In 1776, George Washington crossed the river. This helped his army win a key battle. Today, the river is used for many things. People use it for fishing, travel, and power. 
The Delaware River is a major river in the Mid-Atlantic region of the United States. 

The river works like a giant system that helps many people. It has a huge area called a watershed that drains into it. This area covers 42 counties and 838 towns across five different states. The water is very important for life in the Northeast. It provides drinking water for 17 million people. That is about 6% of all people in the United States. Even half of New York City gets its water through the Delaware Aqueduct. The river is also used for fishing, travel, and making power. It is one of the most used rivers for moving freight. 
Long ago, the river was the home of the Lenape people. They called the river Lënapei Sipu or Kithanne. Kithanne means it is the largest river in that part of the country. Later, explorers from Europe arrived. In 1609, Henry Hudson led an expedition to the river. He was looking for a path to China. Soon, Dutch and Swedish settlers built homes along the lower river. They called it the South River to tell it apart from the Hudson. 
The river eventually got its name from an English nobleman. His name was Sir Thomas West, also known as the 3rd Baron De La Warr. 
Today, the river changes as it moves toward the sea. In the north, it flows through quiet country with farms and forests. These parts are protected as national scenic rivers. But at Trenton, New Jersey, the river becomes tidal. This means the ocean's tides affect the water. In these lower areas, the river is more industrial. It serves big port cities like Philadelphia, Camden, and Wilmington. The river flows into the bay at Liston Point. This is located between Cape May and Cape Henlopen. It is a busy and vital part of the American landscape.
The Delaware River is a major waterway in the Mid-Atlantic region of the United States. 
The river begins with two distinct branches in the Catskill Mountains of New York. The West Branch, also called the Mohawk Branch, rises near Mount Jefferson in Schoharie County. It flows southwest through a deep trough in the plateau. This branch was impounded in the 1960s to create the Cannonsville Reservoir. This reservoir is part of the New York City water system. The East Branch rises from a small pond near Grand Gorge in Delaware County. It flows southwest and is impounded by the Pepacton Reservoir. The Pepacton is the largest reservoir in the New York City water supply. These two branches merge at Hancock, New York, to form the main Delaware River. 
The river follows a complex path through several different landscapes. From Hancock, it flows through a broad Appalachian valley. It passes through the Upper Delaware Valley, which is part of protected national scenic rivers. The river travels 78 miles through rural regions along the New York and Pennsylvania border. At Port Jervis, it enters the Minisink Valley. This is a buried valley where the river flows in a bed of glacial till. The river also crosses the Delaware Water Gap. Here, it moves between nearly vertical walls of sandstone, quartzite, and conglomerate. 
As the river moves south, its character changes significantly. At Trenton, New Jersey, the Delaware becomes tidal. This means the movement of the ocean's tides affects the river's water. In this lower section, the river becomes more industrial and navigable. It serves as the backbone for the Delaware Valley metropolitan area. This includes major port cities like Philadelphia, Camden, and Wilmington. Eventually, the river empties into the Delaware Bay at Liston Point. This point is located between Cape May and Cape Henlopen. 
The Delaware River is part of a massive drainage system called a watershed. This watershed covers 42 counties and 838 municipalities across five states. These states include New York, New Jersey, Pennsylvania, Maryland, and Delaware. The area covers about 0.4% of the total land mass in the United States. In 2001, the watershed was 68% forested, 18% agricultural, and 14% developed. The system contains 216 tributary streams totaling about 14,057 miles. This water provides drinking water for 17 million people. This is roughly 6% of the entire United States population. Half of New York City receives its water via the Delaware Aqueduct.
Long before European settlers arrived, the river was the homeland of the Lenape people. They called the river Lënapei Sipu or Kithanne. Kithanne means it is the largest river in that region. In 1609, Henry Hudson led a Dutch East India Company expedition to the river. He was an English navigator searching for a western route to Cathay, or China. Dutch and Swedish settlers later established colonies along the lower river and Delaware Bay. They called the waterway the South River to distinguish it from the Hudson River. 
The river's current name comes from an English nobleman. He was Sir Thomas West, the 3rd Baron De La Warr.
