List of tributaries of the Allegheny River facts for kids
The Allegheny River is a major waterway in the United States. It flows through parts of New York and Pennsylvania. This river is very important. Many smaller rivers and streams flow into it. These smaller waterways are called tributaries. They bring water to the Allegheny River, helping it grow bigger.
The Allegheny River is part of an even larger system. It joins with the Monongahela River to form the Ohio River. The Ohio River then flows into the mighty Mississippi River. This means all the small streams and rivers mentioned here are connected to one of the largest river systems in the world!
