Fly Fishing South Platte River - Above Spinney

Overview

The South Platte above Spinney Mountain Reservoir is the combined mainstem below the meeting of its Middle and South Forks. It winds through open South Park meadow toward the reservoir inlet. Riffles, bend pools and grassy banks give this Gold Medal reach a setting distinct from the tailwater below Spinney Dam.

Open Meadow Water

Water from both forks shapes this section, with snowmelt and upstream operations influencing depth and clarity. The channel offers defined seams at riffle transitions and deeper holding water in bends. Approach those lies with a low profile; the open valley leaves little cover between an angler and a clear pool.

Wind is part of the meadow setting. A shorter, controlled cast may help place a fly along the bank, while a longer leader can suit a quiet tailout. Read the depth, current and footing at the chosen location before selecting a position.

Fishing the Transitions

Brown and rainbow trout inhabit the river. Work the seam between a riffle and the run below it, adjusting nymph weight to keep a drift in the intended lane. A rising fish in a slower pool calls for a more delicate dry-fly presentation.

Midge, olive, caddis and terrestrial patterns provide useful choices. Match insects observed at the water and keep an attractor available for searching grassy margins. This short river section rewards attention to individual transitions and cover.
