River Map & Access
Below you will find all major points of South Platte River. Message us if you want more added! This doesn’t have the best fishing holes in it, just general points and public access. You’ll notice that the southern and western end of this map have way more points. That is because the river from Cheesman Canyon, through Deckers, and Waterton Canyon are by far the most popular fishing destinations. We have points taking you all the way to the North Platte River convergence in Wyoming.
The Gill trail goes along Cheesman Canyon which provides anglers great walking access to all of the best sections of the river. You can see the map below.
You’ll also see great access to the river in Deckers, and Waterton Canyon.

The River System
The South Platte River flows 308 or so miles through Colorado and converges with the North Platte river after exiting in northeastern Colorado. The headwaters of the South Platte begins in Park County, where the South Fork and the Middle Fork of the South Platte converge near Fairplay. From here, the river flows southeast towards Spinney Mountain Park. The section between Spinney Mountain Park and Eleven Mile State Park is known as the dream stream.
After Eleven Mile Reservoir, the river flows through Eleven Mile canyon towards Lake George.
The river continues northeast towards Cheesman reservoir, into Cheesman canyon, and then into the town of Deckers.
Flowing northeast, the river goes through Waterton Canyon, and eventually straight through Denver, continues northeast, and has other rivers drain into it before they eventually exit Colorado and enter Wyoming.
