About this Water
- Freestone
- Best months: Apr–June & Sept–Oct, peak late Apr–May (Hendrickson)
The Beaverkill is hallowed American fly fishing ground — the 'mother of dry fly fishing' in the United States. Its Catskill pools and riffles gave rise to the Catskill style of fly tying and established the conventions of American trout fishing. The Beaverkill still holds wild brown trout in the public Catskill Center water, and fishing here carries an almost spiritual weight of history.
The Junction Pool, where the Willowemoc meets the Beaverkill, is one of the most photographed and storied pieces of trout water in America.
January Outlook
January on the Beaverkill is deep Catskill winter. This freestone river can freeze in cold years. The birthplace of American fly fishing sleeps under snow and ice. Plan the April Hendrickson trip.
