Flow is steady at 76.3 CFS (gauge height 6.57 ft) with crystal-clear spring-creek water at 54.7°F — prime fall conditions, but expect fish to scrutinize every fly under today's bluebird skies and 83°F high. Long leaders, fine tippet, and drag-free drifts are non-negotiable.

Hatch Chart
| Insect | Size | Activity | Prime Time |
|---|---|---|---|
| Blue-Winged Olive (Baetis) | 20-22 | Heavy | 11 AM - 3 PM |
| Midge | 22-24 | Moderate | 8 AM - 11 AM |
| Pale Morning Dun | 18-20 | Light | 10 AM - 1 PM |
| Caddis | 18-20 | Light | 4 PM - 6 PM |
Best Time Window
- 7 AM - 10 AM: Midge activity in the channels — nymph slowly along weed edges with small dark patterns before the sun gets high.
- 11 AM - 2 PM: Peak BWO hatch window — prime time for dry-fly action with parachutes and emergers to rising rainbows and browns in the flats.
- 4 PM - 6 PM: Evening caddis activity along the banks; switch to a CDC olive dry and work the slower margins as light fades.
Guide's Tip
From the benchWith 83°F air temps and full sun today, the best dry-fly action will be compressed into the midday BWO hatch window — typically 11 AM to 2 PM when cloud shadows or a slight breeze breaks the glare. Run a 12–14 ft leader tapered to 6X or 7X fluorocarbon, and position yourself well downstream of rising fish before you ever make a cast. On Silver Creek, one bad cast spooks the pod; take your time, identify a single target fish, and make your first cast count. If fish are refusing dries, drop to a size 22 nymph on a long, light tippet and dead-drift it just below the film — no indicator, watch your leader for the stop.
