Southwest of Denver, the South Platte River is formed by the convergence of the South Fork and Middle Fork rivers. Its drainage basin, on the eastern side of the Front Range Rocky Mountains, is quite substantial covering large parts of Colorado, Wyoming and Nebraska. Together with the North Platte, they form the Platte River that winds through Nebraska and eventually joins the Missouri River. There are three main areas along the South Platte that are known for great trout fishing, each a unique and worthwhile adventure: Cheesman Canyon, Dream Stream and Eleven Mile Canyon.
Cheesman Canyon has the rarified distinction of being ranked as both a Wild trout and a Gold Medal stretch of water. Known for its huge boulders, arid clime and towering Ponderosas, the river is also considered to be one of the most technically difficult tailwater fisheries in the state. It is also known for rewarding anglers with large rainbows (average 14-16 inches and many over 20) and sizeable browns. Throughout the canyon you can expect to find deep pocket water, rifles and small pools. Fishing is possible year round although it is catch and release only.
Open to the public, the Gold Medal Dream Stream runs from the Spinney Mountain Reservoir to Elevenmile Canyon. Famous for it trophy rainbows, cutthroats and browns, the Dream Stream is also known for its Kokanee salmon that arrive during their fall spawning season. Trout weighing 2-3 pounds are commonplace, while larger fish, including monster 20+ inchers, are also possible. Fish here tend to be skilled at avoiding detection and prepared to put up a good fight, humbling even the most experienced anglers. This 3-mile section is strictly catch and release, artificial lures only.
Between the Elevenmile Reservoir and Lake George, the South Platte flows through a gorgeous canyon with riffles, runs and pocket water. Steep canyon walls protect from wind and offer shade during summer months. Largely a rainbow fishery, browns and cutthroats are also here. Most fish measure over a foot long but much bigger fish can be found. The top two, Gold Medal miles of the canyon have the highest concentration of trout; catch and release only here. Public access to the canyon is excellent, and this year-round fishery can be crowded. Miraculously, the fish seem oblivious, easier to catch here than on other parts of the river.
