How To Fish It

  • Keep the rig shallow enough to drift clean through the softer seam instead of hanging in every slot.
  • Focus on slower shelves, tailout lips, and the soft cushion beside faster current rather than the heaviest riffle water.
  • If fish start showing on top, cut back to one dry and one emerger or a single dry. Long, drag-free drifts matter more than covering more water.

Today's Feeding Pattern

South Platte trout near Deckers feed often but slide into technical behavior fast when flows are clear and stable. Expect fish to hold in the slower seam off the main tongue, on inside shelves, and in buckets where current drops just enough to let them inspect food. They will eat midges and small mayflies all day, but the more visible surface activity usually stays concentrated in specific slicks rather than spreading river-wide.

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.
