The Little Juniata River in Blair County is one of Pennsylvania's finest wild trout streams — a limestone-influenced freestone river producing exceptional dry fly hatches and large wild brown trout throughout its accessible length. The catch-and-release section above Birmingham holds the best fish. The Little Juniata is less famous than Spring Creek or the Brodhead but rivals both for quality. The famous Spruce Creek — an exclusive private tributary — meets the Little Juniata near the prime water, lending some of its exceptional character to the public river.
The Green Drake hatch on the Little Juniata in late May is one of the most reliable and prolific in Pennsylvania — hatches that turn even the most selective wild brown trout into aggressive surface feeders, creating some of the finest dry fly fishing in the eastern US.
January Outlook

Tips
January fishing on the Little Juniata is possible in the spring-influenced sections near Spruce Creek and Birmingham. The limestone-spring character keeps water temperature more consistent than pure freestone streams. Fine tippet and small midges for the selective winter browns.
