About The River

Located in Colorado, the South Fork South Platte River, particularly the area below Antero, holds rich history and natural beauty. This area experienced its first major human impact during the mid-1800s gold rush. Known for the rich deposits, thousands of prospectors flocked to the place seeking fortune.

Interestingly, this stretch of river went through a significant change when the Antero Reservoir was built in 1909 for irrigation and flood control. The reservoir, named after Chief Antero of the Uintah Utes, revolutionized the local agriculture.

  • Popular for its trout fishing, the river’s ecosystem changed with the reservoir’s construction,
  • The dam’s temperature control produced larger trout, making it a major draw for recreational fishing.
Flowing through diverse landscapes from marshy wetlands to rocky canyons, the South Fork South Platte River continues to be a source of water, wildlife, and history to the area below Antero.
