How To Fish It
- Focus on slow, deep runs and shelf water with a drag-free drift.
- Use Double nymph rig under a small indicator.
- Favor Small, realistic profiles with natural coloration.

Today's Feeding Pattern
Clear morning conditions and stable low flows on the South Platte tailwater point to technical subsurface fishing. Trout will feed selectively on midges and small BWOs. A refined presentation is essential for success in clear water.

About The South Platte River
The South Platte near Deckers is one of Colorado's best-known technical trout fisheries, close enough to Denver to see pressure but good enough to keep anglers coming back. Flows are shaped by reservoir management, which gives the river more predictability than a pure freestone stream.
Brown and rainbow trout dominate the fishery. Midges, BWOs, and small caddis patterns carry a lot of the spring workload, and presentation quality matters as much as pattern choice.
