The Green River is running at 1,960 cfs and 55°F following the FWS smallmouth bass flow experiment ramp-down — flows are elevated but clearing, with excellent trout activity across all three sections. Sunny skies and calm winds through Monday set up prime dry fly windows on the A Section, while nymphs and streamers remain the go-to on B and C.
What's Working — Hot Flies
Hatch Chart
| Insect | Size | Activity | Prime Time |
|---|---|---|---|
| Pale Morning Dun (PMD) | #16–20 | Heavy | Morning (8–11 AM) & Evening (5–7 PM) |
| Caddis | #18–20 | Moderate–Heavy | Evening (6–8 PM) |
| Midge | #20–22 | Moderate | Early Morning & Midday |
| Terrestrials (Ants, Beetles) | #12–16 | Moderate | Midday–Afternoon (11 AM–4 PM) |
| Blue-Winged Olive (Baetis) | #20–22 | Light–Moderate | Overcast periods, Late Afternoon |
| Yellow Sally (Stonefly) | #14–16 | Light | Afternoon (2–5 PM) |
Best Time Window
- Early Morning 7–10 AM: PMD hatch peaks on the A Section — best dry fly and emerger action of the day with calm winds and cool air temps around 45–55°F
- Midday 11 AM–2 PM: Terrestrial window opens as temps climb toward 78°F — work ant and beetle patterns along shaded banks and structure
- Evening 5–8 PM: Caddis and PMD spinner fall on the A Section, plus streamer bite heats up on B and C as light drops — prime time for large browns
Guide's Tip
From the benchWith flows at 1,960 cfs following the SMB flow experiment ramp-down, focus your morning on the A Section (Dam to Little Hole) where the PMD hatch is firing hardest — position yourself upstream of rising fish and present your nymph or emerger on a drag-free drift with 6X tippet. As the sun climbs and the hatch fades, switch to a terrestrial pattern and work the grassy, undercut banks where ants and beetles are falling in. On the B and C Sections, commit to a single heavy nymph or streamer and cover water — the bigger fish are holding in the deeper slots and will reward persistence.
