The Little Juniata River (often called the "Little J") is one of Pennsylvania’s premier wild trout fisheries. Flowing through central Pennsylvania, this limestone-influenced river provides cold, fertile waters that sustain a strong wild brown trout population. With excellent hatches, productive riffles, and deep pools, the Little J is a classic freestone river with spring creek characteristics, making it a top fly fishing destination.

Fly Fishing the Little Juniata River: The most productive section of the Little J runs from Tyrone to Spruce Creek, with much of the river designated as Catch-and-Release, All-Tackle regulations. This stretch holds a high density of wild brown trout, with fish commonly reaching 14-18 inches and larger specimens exceeding 20 inches.

Hatches & Flies: The Little Juniata River is famous for its consistent and diverse hatches, making it an excellent dry fly fishery. Key hatches include:

• Blue-Winged Olives (BWO) – Early spring and fall

• Grannom Caddis – April

• Hendricksons & March Browns – Late April to May

• Sulphurs – May to early June (one of the best hatches)

• Green Drakes – Late May to early June (sporadic but exciting)

• Slate Drakes – Summer through fall

• Tricos – July through September (early morning spinner falls)

• Terrestrials (Beetles, Ants, Hoppers) – Mid to late summer

Best Times & Tactics

• Spring and early summer offer the best dry fly action, with major mayfly and caddis hatches.

• Sulphur hatches in May and early June bring epic evening fishing opportunities.

• Nymphing with Pheasant Tails, Hare’s Ears, Caddis Pupae, and Walt’s Worms is productive year-round.

• Streamers work well for targeting larger browns, especially in high water or low light conditions.

• Fall provides excellent fishing with Slate Drakes, BWOs, and aggressive pre-spawn brown trout.

With wild trout, prolific hatches, and scenic beauty, the Little Juniata River is a must-visit destination for serious fly anglers.
