Bivisible fly Rusty Dunn

Fountains of Youth – Classic trout flies that have withstood the test of time … flies that remain “forever young”

by Rusty Dunn

Have a sip of New York City municipal water, and you’re drinking a cup of fly-fishing history. About half of The Big Apple’s water supply comes from the Catskill Mountains, birthplace of American fly fishing. The Catskills are where Theodore Gordon began the “Cats­kill style” of fly tying, where George LaBranche and Edward Hewitt pioneered and popularized American fly fishing, where Preston Jennings com­piled the first com­prehensive list of aquatic insects available to North American trout, and where the H.L. Leonard and E.F. Payne rod compa­nies tested and built some of the fin­est split cane fly rods ever made. The historic Neversink River was a Catskill laboratory for these and many other angling ad­vances. Its glory, however, has yielded to the march of time. Most of the Neversink’s waters are now siphoned off to the mouth of the Hudson, where they irrigate and cleanse millions of New Yorkers who’ve never heard of a Quill Gordon or a Light Cahill. The very pools where American fly fishing began, includ­ing river miles owned by Gordon and Hewitt, now lie beneath a water storage reservoir. May they rest in peace.

Edward R. Hewitt (1866-1957) honed his fly-fishing knowledge and skills on the Neversink. His contribu­tions to angling are the stuff of legend. He in­vented and patented the felt-soled wading shoe, built one of the ear­liest interchangeable fly reels, bred poultry ex­pressly for the quality of its dry-fly hackle, and es­tab­lished The Big Bend Club, a fishing camp on the Neversink that was a Mecca for fly-fishing luminaries. Hewitt’s early books, Secrets of the Salmon (1922) and Tell­ing on the Trout (1926) were pub­lished at a time of rapid growth in fly fishing and had a big im­pact on a country thirsting for good fly-fishing information. Hewitt was, above all, a conservationist, one who managed

his river miles meticulously and advocated catch-and-release fishing at a time when the number of Catskill trout seemed inexhaustible.

Hewitt is perhaps best known for his observation that most fly anglers progress through three successive phases of maturation: a phase of wanting to catch the most trout possible, followed by one of seeking the larg­est fish possible, followed by one of attempt­ing to land the most difficult and selective fish, caring more for the sport than number or size of landed fish. Hewitt lived a long rich life, and he spent many satisfied decades in phase three of matu­ration. For example, he was the first angler to land an Atlantic salmon using a dry fly and a 1-1/2 ounce 4wt bamboo fly rod! It was a re­markable feat, although local fishing guides de­scribed it as “the salmon that caught Mr. Hewitt”.

Hewitt hooked the infamous salmon on a Bivisible dry fly, which, along with the Neversink Skater, are Hew­itt’s two most famous flies. Both are high floating flies suit­able for gentle slicks, turbulent riffles, and every­thing in between. The name “Bivisi­ble” indi­cates that the fly is visible to both trout and angler. A palmered darker hackle pro­vides floata­tion and visi­bility to trout, while a contrasting collar of white hackle provides visibility to an angler. The fly is derived from an ancient English pat­tern, the Palmer Sedge, which Hewitt spiced up with the collar of white.

The Bivisible is a fluttering fly, a fly for skating, skit­ter­ing, and enticing a lazy trout. A fly so buggy it can’t be ignored. It imitates egg-laying caddis very well, but it also brings up fish between hatches, espe­cially on the warm breezy days of terrestrial season. It is a fly for fishing the water, not the rise. One with which to cre­ate George La Branche’s proverbial “hatch of frauds”. In short, the Bivisible is a classic attractor, one that has caught fish for over a cen­tury. Don’t be afraid to jerk a Bivisible underwater and fish it as a wet fly swung in the current or retrieved with short strips. It may look like no insect you’ve ever seen, but a Bivisible will still grab a trout’s atten­tion.
