Rio Costilla- 60cfs out of dam- Public waters closed. Dry flies and droppers and great fish activity. Stoneflies, caddis, hoppers. PMD hatch early afternoon, with fish keying in on emergers. Quigley's cripple a good fly choice for that scenario. Water temps on the lower stretches tend to rise in the afternoons and fishing activity slows.
Red River- 45 cfs below hatchery- Hatchery is closed; only access via BLM down in the canyon. I fished the Red yesterday (Sunday) at Aguaje in Wild Rivers and was surprised to find the parking lot empty. I used the same large scruffy dry all day. Took browns to twelve inches in every pocket. It's good to be home.
Cimarron- 46 cfs out of dam- Public waters closed. Dries and droppers working well for browns and bows. Caddis always a good bet.
Culebra-80 cfs at San Luis bridge-The Culebra is off color and at a nice flow. Tough fishing for beginners with limited visibility and little top water action, but the fish are there, eating and catchable. Nymphing with cranefly larvae, caddis, worms, and golden stones. Streamer fishing is the best bet to move the most fish and cover the most water.
