South Platte River

 River: South Platte has many tributaries. The main three forks are the South Fork, the Middle Fork and the North Fork. The South Fork starts in South Park near Weston Pass and runs into the Antero Reservoir; it continues to Hartsel near where it is dammed to form Spinney Mountain Reservoir. The Middle Fork runs out of Montgomery reservoir into South Park, through the Tomahawk State Wildlife Area near Hartsel and then into Spinney Reservoir. The North Fork begins near Kenosha Pass, follows highway 285 through Bailey, then joins the South Platte near Pine.

Water: The South Platte has many miles of diversified types of water, including meandering meadow stretches with undercut banks, deep canyon stretches with deep plunge pools and all types of riffle, fun, pool, flat configurations. The South Platte has all Colorado river’s water types.

 Access: There are miles of fishable water on the South Platte system. Some of the more popular access areas include the Tomahawk SWA, Badger Basin near Hartsel, Spinney Mountain Reservoir and the river between that impoundment and Eleven Mile Reservoir (this stretch is called the “Dream Stream” by many); Eleven Mile Canyon below Eleven Mile Reservoir; Cheesman Canyon; the Deckers area and downstream through Waterton Canyon. Private access areas on the river are clearly marked and many are very private! Do not trespass on the Platte!

Fish: Primarily browns and rainbows, although rainbow populations are down due to Whirling Disease. There are also cutthroat trout in the Spinney area and hybrids, too. Average size is 12-16 inches, with many larger fish possible, including trophy size fish in certain tail water areas below Spinney and Cheesman reservoirs.

Bugs: The South Platte offers some of the finest tail water fly fishing in the country. The river abounds in all types of mayflies, caddis, stoneflies and midges. In meadow stretches as well as canyon waters there are many terrestrials, such as hoppers, ants and beetles. Certain areas are known for great hatches of BWO's in Spring and Fall months, as well as wonderful winter midge fishing.

Flies: Many standard tail water patterns have been developed specifically for the South Platte. The bugs are often small – 18-26. Midge patterns such as Griffith’s gnats, disco midge larva patterns, WD-40, Dale’s midge adult, stuck-in-the shuck and small buckskin patterns work well. Mayfly patterns will run from size 16-24 and include BWO patterns such as Lawson’s Thorax Beatis, Olive Comparadun, AK’s parachute olive quill, Barr emergers, RSII, pheasant tail nymphs – including BH and flashback PT’s and many other local patterns. PMD’s are prolific during summer months and trico’s begin hatching during the late summer and often continue through the fall months. Tan, peacock and olive caddis patterns are a must during summer months in sizes 14-20. Golden stonefly nymphs and adults are important in some areas. Many anglers enjoy fishing San Juan Worms, glo-bugs or scuds in olive, tan or orange with small nymph droppers. Also, streamer patterns can be very effective.

Techniques: the tailwater stretches will often demand longer casts and good drifts in order to hook spooky fish. Many anglers develop more advanced fly fishing techniques by fishing the South Platte system. Accurate casts and good drifts are almost always called for while fishing the Platte. A good dry fly approach is to fish down and across the stream. Nymphing means swimming the fly into a fish’s mouth at times as they will not move very far to take a fly pattern.

Seasons: there is no closed season on much of the Platte because it is a tailwater fishery. Water temperatures stay relatively stable for much of the year. There are a wide variety of insect hatches and something new is always in store on the Platte. Winter months offer some of the most dependable fishing we have on the Front Range of Colorado with prolific midge hatches possible.

Rating: The South Platte is an excellent fishery. It is rates as one of the best in the West! Numerous books and magazine articles have been written about this stream. Count on having a lot of company with other anglers because the fishing is great. The scenery is beautiful, as well.

The South Platte is a pretty dammed up river. It's also a darned good fishing river! Development takes its toll, resulting in the dams everywhere. Originally, the South Platte was the highway into Colorado as French trappers found their way up the Platte River from the Missouri, splitting off on the South and it's tributaries during the early 1800's.

The South Platte finds its source in the mountains south west of Denver near an area called South Park. There are several tributaries that join west of a man made impoundment called Spinney Mountain Reservoir. The stretch of river below Spinney and above the next Reservoir - Eleven Mile - is referred to as "The Dream Stream". It is short, but arguably has been one of the most productive stretches of river anywhere. There are big fish that both reside and migrate into the stream to live and spawn. Very large Brown, Rainbow and Cutthroat trout are caught here each year. There are wonderful hatches of midges, mayflies and caddis, as well as great terrestrial activity. The stream is known for its Trico hatches during late summer and early fall months.

The  next popular and historic part of the Platte is Cheesman Canyon, so named for the dam that once again stops up the stream. The Canyon stretch is reached by a short hike and is about three miles in length. This was the first catch and release stretch of water in the state of Colorado and continues to be a prime fly fishing only area. The Canyon is the finest piece of trout water that is in close proximity to a large metropolitan area. It can be reached from Denver and Colorado Springs in about one hour. Below the Canyon is the very private and exclusive Wigwam Club, which ends just above the town of Deckers. The area below Deckers, through Trumball and on down stream is open to fly fishing, except where it's posted. These spot also get lots of pressure, but continue to produce fine fly fishing for Brown and Rainbow trout. There are also a few Brook trout around. The Canyon has good hatches of midge and mayfly insects, as well as good terrestrial fishing in season. There are also scuds in the water.

The best time to fish the Platte in these areas is as soon as you can. Beware of water fluctuations, as the powers that be whimsically vary the flows below the dams. The Platte is a beautiful river that holds lovely trout that will eat flies. What more do you want?
