Silver Creek is running at 98.3 CFS with a gauge height of 6.68 ft and a water temperature of 57.6°F — ideal spring-fed conditions with exceptional clarity that demand precise, stealthy presentations. Expect strong PMD and Callibaetis activity through the week with BWOs firing on overcast mornings; watch for gusting westerly winds Sunday that may complicate dry-fly work.

Best Time Window
- Early morning (6–9 AM): Midge and BWO activity peaks in low light; approach quietly and fish the film with small patterns before wind builds.
- Mid-morning to early afternoon (10 AM–2 PM): Prime PMD and Callibaetis window on sunny days; look for steady risers along weed-lined flats and spring seeps.
- Late afternoon to evening (4–7 PM): Caddis hatch fires as light drops; also the prime window to watch for the approaching Brown Drake emergence along Silver Creek West.
Guide's Tip
From the benchSilver Creek's gin-clear spring water means trout will inspect your fly from several feet away — rig a 12–15 ft leader tapered to 6X (drop to 7X during the calm midday window) and approach every rising fish from directly downstream with a low profile. With Sunday's westerly gusts forecast up to 29 mph, time your dry-fly presentations for the morning calm before 10 AM or wait for the wind to ease in the evening caddis window. Identify exactly what stage the fish is eating — a trout sipping in the film during a BWO hatch is a completely different target than one bulging on PMD emergers just below the surface — and match the stage, not just the species. Keep an eye on social media for the Brown Drake hatch, which could fire any evening this week along Silver Creek West.
