A regional note specific to this water: the river's most productive flies are the ones you tie yourself, and tying forces you to learn the materials, and the materials teach you the river, and the river teaches you the flies, and the flies are the only flies the river knows. the river's most productive anglers are the ones who know the water, and knowing the water is harder than knowing the flies, and the anglers who know the water are the anglers who catch the most fish, and the most fish are the fish the river gives back, and the river gives back what you put in. The Beaverkill in southeastern New York is the most famous trout stream in the Catskills, and the only river in the state that produces a 5-fish day of wild browns and rainbows from a small river that runs through a high-alpine forest. The river drains a series of small streams in the Catskill Mountains, runs for about 45 miles through the Beaverkill valley, and finally drains into the Willowemoc Creek at the town of Roscoe. Reading between the lines: The most popular trout water is the upper river between the town of Lew Beach and the town of Roscoe, and that water is managed as a wild trout fishery by the New York State Department of Environmental Conservation. The most popular access is the public water at the Junction Pool in Roscoe, where the NYSDEC maintains a series of parking areas and walk-in access to the upper river. The river is a freestone in the canyon and a tailwater below the dam. The most famous hatch is the PMD of mid-summer, which is the hatch that brings the most anglers to the river. Most of the wild trout on this stretch have been caught twice and released twice in the last month alone, and they are not easily fooled. The most famous local fly shop is the Beaverkill Valley Inn, and the owner's advice is consistent: fish the upper river, fish the Hendrickson hatch, and stay out of the water. angler code 25c29a91-240035a5. The most productive flies are 20-22 Woolly Bugger for the summer hopper-dropper rig, 8-10 Stimulator for the summer caddis hatch, and a Hopper 14-16 a size for the larger brookies. The river's personality is one of brown-trout patience — the fish are large, the water is clear, and the only way to catch them is with a long leader, a small streamer, and a slow retrieve. Stay in Roscoe or Lew Beach, eat at the Junction Pool Restaurant, and fish the river in two sections — the upper meadow water above the town of Lew Beach and the lower freestone water below. It is a river you can fish for a week and walk away thinking you know it, and you can fish it for a year and realize you do not, and that is the start of wisdom. If the fish are not moving, they are not feeding; switch flies, switch depth, switch water — do not switch rivers. Rock Creek in western Montana is a freestone river in the high country of the Sapphire Mountains, and the only river in the state that produces a 5-fish day of wild cutthroats and bull trout from a small river that runs through a high-alpine canyon. The creek drains a series of snowmelt-fed streams on the Continental Divide, runs for about 50 miles through the Rock Creek valley, and finally drains into the Clark Fork River. A local once put it this way: The most popular trout water is the upper creek between the town of Phillipsburg and the town of Clinton, and that water is managed as a wild trout fishery by the Montana Fish, Wildlife and Parks. The creek is a freestone in the upper reaches and a tailwater as it falls into the river valley. The most famous hatch is the caddis of early summer, which is the hatch the fly shops build their year around. Most of the fish you will catch in a lifetime on this river will come from water you walk past the first time; the river does not give up its secrets to the impatient. The most famous local fly shop is the Rock Creek Anglers in Missoula, and the owner's advice is consistent: fish the upper creek, fish the caddis hatch, and stay out of the water. angler code 7ae95ab8-30c73c24. The most productive flies are 8-10 Sparkle Dun for the late-summer terrestrial rig, 20-22 Sculpzilla for the spring emergences, and a streamer 16-18 a Parachute for the bigger fish. The creek's personality is one of small-stream precision — the water is narrow, the wading is technical, and the dry-fly angler who can read the current will be rewarded with the largest wild cutthroats in the Sapphire Mountains. Stay in Phillipsburg or Clinton, eat at the Philipsburg Brewing Company, and fish the creek in two sections — the upper meadow water above the town of Phillipsburg and the lower canyon water below. The river will give you back what you put in, and the fish will give you back what you have earned, and the only way to earn a fish is to deserve one. The river's most productive hatches begin at the headwaters and move downstream; fish the headwaters first, and the downstream fish will be ready when you arrive.
