Beaverkill River, one of the most famous trout streams in the United States is a tributary of the East Branch of the Delaware River, in the U.S. State of New York.

The Firehole River  a major tributary of the Madison River in Wyoming has its source in Madison Lake on the Continental Divide and flows through several significant geyser basins in Yellowstone National Park before joining the Gibbon River at Madison Junction.
