Willow Creek
spring creek in Idaho
Often overshadowed by its larger neighbor, Willow Creek offers excellent wade fishing for rainbow and cutthroat trout, particularly during strong insect hatches. This eastern Idaho spring creek, feeding into the South Fork of the Snake, is often overlooked but highly productive. Its stable temperatures and abundant aquatic insect life create prime conditions for consistent dry fly and nymph fishing, holding strong numbers of rainbow and Yellowstone cutthroat trout.

Buy at AmazonBlue-Winged Olive (BWO) Comparadun
Consistent fall BWO hatches are a primary food source on spring creeks, and this low-profile dry fly is excellent for selective trout keying on adults.
Buy at AmazonPine Squirrel Leech (Olive)
Small leech patterns effectively mimic sluggish baitfish and annelids in cooling fall waters, enticing strikes from larger, lethargic trout.
Travis Hi-Vis BWO Para Emerger
BWO emergers are crucial during fall hatches. This pattern's high visibility helps detect subtle takes from selective trout in the film.
Scud (Pink/Orange)
Freshwater shrimp (scuds) are a consistent food source in spring creeks with aquatic vegetation, making this a reliable subsurface pattern year-round.
Buy at AmazonZebra Midge (Black)
Midges are a primary and consistent food source in spring creeks year-round. This weighted nymph gets down to feeding trout, especially in colder fall water.
Blood Dot Egg
As fall progresses, some trout species may begin spawning or stage below spawning fish. Egg patterns can be highly effective for opportunistic feeders.
Buy at AmazonOctober Caddis (Dry)
The October Caddis hatch is the largest caddis hatch of the year in many Western rivers, providing excellent dry fly opportunities in the fall.
