13.5-Foot Supple Euro Nymphing Leader

A 13.5-foot euro nymphing leader that loops to the fly line. It steps down evenly through 42" each of .016", .014" and .012" mono into an 18" 3X (.008") sighter and 18" of 5X (.006") tippet. The even taper turns over a weighted nymph softly, and the fine tippet lets a small tungsten fly sink fast.

How to tie it

  1. Build the tapered leader

    Join the 42" butt to the 42" mid with a blood knot. Add 42" of .012" with a triple surgeon's knot. Add 18" of 3X with a triple surgeon's knot. Add 18" of 5X with a triple surgeon's knot.

The knots

  • Blood knot · 5 turns×1
    1. Overlap the two ends by about six inches.
    2. Wrap one tag end around the other line five times, then bring it back and pass it between the two lines where they cross.
    3. Wrap the other tag end five times the opposite way and pass it back through the same opening from the other side.
    4. Wet the knot and pull the two standing lines steadily until the wraps seat. Trim both tags close.

  • Triple surgeon's knot · 3 turns×3
    1. Lay the new line alongside the end of the leader so they overlap about six inches, the ends pointing opposite ways.
    2. Holding the two lines as one, tie an overhand knot, passing the whole new piece through the loop.
    3. Pass the same ends through the loop twice more, three times in all.
    4. Wet it and pull all four ends evenly to seat the knot. Trim the tags.

  • Improved clinch knot · 5 turns×1
    1. Pass the tippet through the hook eye and pull about five inches through.
    2. Wrap the tag around the standing line five to seven times.
    3. Pass the tag through the small loop just above the eye, then back through the large loop you just made.
    4. Wet it and pull the standing line so the wraps snug down against the eye. Trim the tag.

When and how to fish it

Fish riffles, pockets and seams at short range on a 3-5 wt. Lob a size 16 tungsten-bead nymph upstream, raise the rod until the sighter hangs just off the water, and lead the fly downstream at current speed. There is no indicator or split shot: the bead gets the fly down and the sighter shows the take. Set on any stall, twitch or sideways move.

If the sighter never stalls or ticks, the fly is not reaching bottom. Go up a bead size before you add length to the drift.

Common questions

  • Does this rig use split shot or an indicator?

    No. It is a tight-line rig. A tungsten-bead nymph carries the weight and the 3X sighter shows the strike.

  • Which tippet should I use?

    The build is the same up to the tippet: 18" of 5X (.006") for small flies and clear water, or 4X (.007") for heavier flies and bigger fish.

  • Why three long butt sections?

    The .016", .014" and .012" steps let the leader turn over a weighted fly smoothly while staying light enough to hold off the water.

  • Can I fish two flies?

    This build has one fly. A second weighted nymph would get it deeper, but it also adds tangles on the 5X.

  • Lake Almanor, Ca. Hex Hatch Slip Bobber Dredging Rig

    Featured

    I built this rig to get a weighted hex fly down to the lake bottom where trout are waiting for natural hex emergers to rise up the water column. It uses a slip bobber to suspend the fly 12 to 24 inches above the bottom in 15 to 35 feet of water, letting me fish without casting while the fish camp in place before they start moving up to chase the hatch.

  • Hogan's Yuba River Nymph Rig (fall/winter)

    This is my go-to setup for Fall/winter nymphing on the Lower Yuba River. I adjust the weight between AAA, SSG, and AB as well as move the indicator up and down fish varios depths and speeds of water... shallower water lighter weight.

  • Thin Mono Rig with a .012 Butt

    A long thin mono rig for euro nymphing: 312" of .012" Maxima Chameleon, a 24" sighter of 12" of Umpqua Sighter and 12" of RIO Two Tone Indicator (both .009"), and 48" of 5X fluorocarbon tippet to a tungsten bead nymph. Triple surgeon's knots join the sections. At 384" overall the thin butt does the work a fly line would, with far less sag.
