Fly Fishing Pecos River - Upper

Overview

The upper Pecos between Cowles and the Village of Pecos flows through southern Sangre de Cristo canyon country. Mixed conifer and aspen frame boulder pockets, bedrock pools, riffles and short glides. Brown and rainbow trout occupy the main river, while native Rio Grande cutthroat trout are part of the wider upper-drainage fishery.

The intimate water suits a short, accurate cast to a sheltered pocket. Look for a softer seam behind a rock or depth beneath a plunge before placing the fly. A shorter light rod can help with tight casting, while a controlled drift matters more than covering several currents at once.

Baetis patterns provide spring mayfly choices, with caddis and smaller stoneflies adding warmer-season options. Parachute Adams, Elk Hair Caddis and Royal Wulffs offer searching dries for broken water. Foam beetles and hoppers can cover vegetated edges, with a Pheasant Tail or Prince nymph on a dropper for subsurface feeding.

Snowmelt and mountain storms influence depth and clarity. Adjust the cast and nymph weight to the chosen lie, and watch for visible insects or rising fish before settling on a pattern. The river’s short pools and forested margins give this canyon section its small-stream character.
