The longest un-dammed river in the contiguous USA is the Yellowstone River; it is 692 miles long.
Rivers provide drinking water, irrigation water, transportation, electrical power, drainage, food, and recreation. While some of the USA rivers and lakes serve as vital waterways for inland navigation others are useful sources of irrigation and power generation.
Besides the USA rivers, the USA river map also shows the various lakes, streams and other water bodies in the USA.

The United States is a large country with a wide range of physical features, from tall mountains to deep valleys, rivers, lakes, and plains.
Mississippi - Part of the longest river system in the United States, the Mississippi runs from Minnesota down to New Orleans, Louisiana, where it drains into the Gulf of Mexico.
Colorado - The Colorado River runs through the southwest, beginning in the Rocky Mountains, through the Grand Canyon, and finally flowing down into Mexico. Rio Grande - One of the longest rivers on the continent, the Rio Grande flows from Colorado down to Texas, forming part of the US-Mexico border.

The longest river in the USA is the Missouri River; it is a tributary of the Mississippi River and is 2,540 miles long. For certain cities like New Orleans, river basins usher in growth and prosperity for the city and its people.
