The South Platte River below Spinney Mountain Reservoir is one of the most famous tailwater fisheries in North America. Located about 2 hours southwest of Denver in the area known as South Park, this relatively short meadow stretch of the Platte is a year-round fishery and produces some of the largest trout in the state during annual spring (Rainbow and Cutthroat trout) and fall (Brown trout and Kokanee Salmon) spawning runs out of Elevenmile Reservoir, some into the mid two digits weight wise. The resident fish are no joke either, consistently reaching sizes over 18 inches. This is an amazing stretch to fish when the action is good, but it is fairly technical water and can be a true challenge at times even for an experienced angler.
Elevenmile Canyon starts just below Elevenmile Reservoir. Although the reservoir is situated on the open/ windy plateau of South Park; Elevenmile Canyon a completely different scenario all together with pine and fir trees, tremendous rock outcroppings, and gorgeous plunge pools. The installation of changes in DOW regulations since 2001 have improved and preserved this fishery. Elevenmile Canyon is now artificial flies and lures only, and catch and release, for the four miles below the dam (to Springer Gulch). This fishery proves to be one of the most consistent tailwater fisheries in the state day in and day out.

Charlie Myers SWA "Dream Stream" below Spinney Reservoir

General Conditions

While the Trico activity may be waning a bit, fish are still feeding heavily in these fantastic flows. Your mornings are still the most productive hours, and you will find some sporadic Trico Spinnerfalls in the 8-10AM window. Nymphing can be your bread and butter however, with fish stacked in deep cuts feeding on a variety of bugs in the nymph and emerger stages.

Suggested Techniques

Things are beginning to turn into a BWO and Midge focus, with some remaining strong Trico activity at times. Focus on your heavier nymph rigs unless you see a number of fish up, at which time you can change to a dry/ merger or dry/ spinner rig. Fish are still focused heavily on Tricos, but sometimes more in the mid and deep sections of the water column, so running trico nymphs and emergers deep below a BWO nymph or attractor nymph will be very productive. Have your spinners ready for the late morning, as you will see some localized but heavy Trico spinner falls in the 8-10AM window. 

Elevenmile Canyon below Elevenmile Reservoir

General Conditions

Much the same as the Dream Stream, with cooler temperatures, this section is beginning to transition from heavy Trico activity to more of a BWO and Midge focus. You will see fish a bit more opportunistic on this section however, and dry dropper rigs with hoppers and attractor dries can still be very productive. 

Suggested Techniques

We have seen hatches of Tricos, BWOs, Midges and small Caddis on this stretch...all of which occur at different times throughout the day. Our guides focus on those hatches when fish are keyed on the surface or on emergers. If you aren't on a keyed hatch, nymphing various attractor nymphs along with BWO and Trico nymphs or Midge Larva...will be productive in deeper riffles and tailouts.
