Real-time USGS gauge data was unavailable in the authoritative feed; guide services report flows near 1,000–1,250 cfs with water temps in the 50–54°F range — ideal trout conditions. **Critical heads-up:** Flaming Gorge Dam will ramp to full power-plant capacity June 8–11 for the SMB flow experiment, so wade anglers should fish hard today and Monday before flows spike.

Hatch Chart
| Insect | Size | Activity | Prime Time |
|---|---|---|---|
| Pale Morning Dun (PMD) | #16–20 | Strong — emergers and duns on A-Section flats | Morning & evening |
| Caddis | #16–20 | Active — adults egg-laying at dusk | Late afternoon to dark |
| Cicadas | #8–10 | Sporadic — triggered when ground temps hit mid-60s°F | Midday warmth |
| Terrestrials (Ants, Beetles) | #14–18 | Building — warm afternoons bring fish to the surface | Afternoon |
| Blue Wing Olive (Baetis) | #18–22 | Moderate — best on overcast or stormy windows | Overcast midday & evening |
| Yellow Sally Stonefly | #14–16 | Early season — beginning on B & C sections | Afternoon |
Best Time Window
- Early morning (6–9 AM) — PMD emerger action on A-Section flats before wind builds
- Late afternoon to dusk (5–8 PM) — Caddis egg-laying flights and terrestrial activity peak; overcast Monday/Tuesday windows may add BWO risers
- First light Monday (pre-6 AM) — Streamer bite on B & C sections before afternoon gusts; last best wade window before June 8 flow ramp-up
Guide's Tip
From the benchFish hard today and Monday morning before the SMB flow experiment ramps Flaming Gorge Dam releases up on June 8th — wading will become dangerous and the fish will go off the bite as flows surge. During the PMD window, position yourself upstream of rising fish and present your emerger pattern with a reach cast to get a drag-free drift through the feeding lane. When the afternoon clouds build (as forecast Monday and Tuesday), switch to a BWO parachute and work the slower inside seams where fish stack up during overcast conditions. If the wind picks up to the forecast 35 mph gusts, abandon dry flies and go deep with a heavy jig nymph — the fish will be hugging the bottom.
