Colorado’s hundreds of rivers, creeks, and streams are fueled by snowmelt high in the Rocky Mountains. They provide life to millions of residents and even more native wildlife, from birds and moose to plants and insects.
Some rivers are more well known than others and many flow out of state. There are more than a dozen major rivers in Colorado, like the Rio Grande, Arkansas, and Colorado rivers.
Here are the ten largest rivers in the state:
- Rio Grande River – 1900 miles
- Arkansas River – 1470 miles
- Colorado River – 1450 miles
- Canadian River – 900 miles
- Green River – 730 miles
- North Platte River – 720 miles
- Cimarron River – 700 miles
- Smoky Hill River – 575 miles
- South Platte River – 440 miles
- San Juan River – 385 miles

Most of the big-name rivers provide opportunities for whitewater rafting, and nearly all of the waterways offer fishing in some form. Take a look at some of the native fish in Colorado. All fishermen over 16 years old need a valid Colorado fish license.
Whether it’s simple sightseeing or in-water recreation, Colorado’s rivers and creeks provide a sanctuary for all. Please take care of one of the state’s most precious resources, its water.
