List of Delaware River tributaries facts for kids

The Delaware River is a very important river in the eastern United States. Its watershed is like a giant funnel that collects water from a huge area. This area covers about 14,119 square miles (36,568 square kilometers). It includes parts of five states: New York, New Jersey, Pennsylvania, Maryland, and Delaware. This watershed makes up about 0.4% of all the land in the United States.
The Delaware River starts high up in the Catskill Mountains in Upstate New York. It flows south for 419 miles (674 km). Finally, it reaches Delaware Bay, where its waters mix with the Atlantic Ocean. This happens near Cape May in New Jersey and Cape Henlopen in Delaware. Many smaller streams and creeks flow into the Delaware River. There are about 216 of these "tributaries," adding up to over 14,000 miles of waterways!
People use the water from the Delaware River basin for many things. It's used for fishing, transportation, and making electricity. It also helps cool down power plants and is great for recreation like boating. Most importantly, this river provides drinking water for 17 million people. That's about 10% of the entire U.S. population! Even though it's the 33rd largest river by how much water flows, it's one of the busiest for moving goods by boat every day.

What is a Watershed?
A watershed is an area of land where all the water drains into a single river, lake, or ocean. Think of it like a giant bowl. When rain or snow falls anywhere in that bowl, the water eventually flows down to the lowest point. For the Delaware River, all the rain and snow that falls in its watershed ends up in the river itself.
