Picked from reports, hatches and the season. Tap a fly for the recipe and where else it works.

Coho (Silver) salmon are known to aggressively strike anything pink, and this pattern is a highly effective imitation of leeches and baitfish for these active fish during the fall.

A versatile streamer pattern that imitates leeches and baitfish, which are consistent food sources for predatory trout and char in the colder fall waters.
Orange Flash Streamer
A specific attractor streamer ideal for Dolly Varden and highly effective for various salmon species and rainbow trout in Alaska's clear waters during the fall.
White Bunny Leach
Imitates decaying salmon flesh and white belly sculpins, which are prevalent food sources in the fall. The rabbit fur provides effective movement even with a very slow retrieve in cold water.
Mouse Pattern
