About Logan River Fishing
The Logan River is a productive tailwater and freestone hybrid offering anglers accessible quality fishing just minutes from Logan city. Three small impoundments on the lower section provide family-friendly opportunities with stocked rainbows, while the river stretches between dams hold healthy populations of large wild rainbows and browns.
Best Time to Fish Logan River
The Logan River fishes well all summer with classic attractor patterns like Royal Wulff, Humpy, Rainbow Warrior, and Prince Nymph consistently producing. A distinctive feature is the Green Drake hatch in May and June, followed by a second run of Grey Drakes in August and September—a local secret that extends prime dry fly fishing into late season.
Species
Rainbow trout dominate the Logan and respond eagerly to both dry flies and nymphs throughout the season. Brown trout populations vary from modest in the impoundments to robust in the river sections, where they grow large and can be targeted with bigger attractor patterns and subsurface presentations.
