Colorado South Platte River

Characteristics updated almost 2 years ago
Flow updated about 2 hours ago
Available Segments 2

The South Platte River is a major river in the state of Colorado. It originates in the Rocky Mountains in the north-central part of the state and flows south through Denver, which is joined by the North Platte River. From there, it continues south through the eastern plains of Colorado and eventually empties into the Mississippi River. The river is a popular destination for fishing and rafting, and it is also an essential source of water for irrigation and other purposes.

As mentioned above, due to its proximity to the Front Range, it can get jam-packed. The river is known for its wild and beautiful brown and rainbow trout. The South Platte is a tailwater fishery. Some of the more popular segments, particularly during the warmer months, are Waterton Canyon, Deckers, Cheesman Canyon, and the Dream Stream.
