Conditions as of June 3, 2026 · Early Summer
The Quick Read
Three very different rivers, three different games this week. The South Platte is running high and cold with Antero releases — a nymph and streamer story. The Arkansas is trending fishable with excellent clarity and a building caddis-and-baetis bite. The Roaring Fork is low and clear, technical, and rewarding careful presentation. Match your river to your mood, but keep your flies small and your drifts honest.
Current Conditions
The South Platte (11-Mile Canyon) is running 38°F with Antero releases pushing higher flows through the upper sections; dry/dropper, nymphing, and small streamers are favored. The Arkansas is 60°F with excellent clarity through all basins and is trending more fishable as cooler weather slowed snowmelt. The Roaring Fork is 56°F, low and clear except after storms, with flows reported at 82 CFS below Maroon Creek (upper), 400 CFS at Basalt (middle), and 950 CFS at Glenwood Springs (lower).
What's Biting
Trout on all three. The South Platte is a subsurface game with higher flows — rainbows, browns, cutthroat, and cutbows. On the Arkansas, browns and rainbows are active, with caddis leading in the middle basin, baetis important on cloudy afternoons, and yellow sallies, red quills, PMDs, and early hoppers showing below town. On the Roaring Fork, trout are eating caddis, blue-winged olives, midges, stonefly nymphs, and sculpins, with the upper and middle reaches especially technical in the low, clear water.
What to Throw

Technique & Where-To
On the South Platte, fish dry/dropper and nymph rigs first and add small streamer strips when water rises. On the Arkansas, fish caddis-driven dry-droppers, then switch to baetis and PMD emergers on cloudy afternoons; fluorocarbon and 5X are recommended for subsurface work in the low, clear water. On the Roaring Fork, concentrate on deeper runs, pools, and slower water — especially upper and middle river — keep flies small, use enough weight to get down, and expect subtle takes.
Seasonal Outlook — Next Few Weeks
The South Platte should keep fishing well with sustained runoff-driven flows up top, favoring nymphing and streamers before conditions settle. The Arkansas should improve further as snowmelt moderates, with caddis, baetis, and early-summer mayflies getting more consistent and dry-dropper fishing strengthening. The Roaring Fork is entering a technical early-summer phase where low, clear water makes presentation and small patterns critical, but caddis and BWO opportunities should stay solid, especially on warmer and cloudy days.
