Micro-Thin Mono Rig for Small-Stream Euro Nymphing

A thin, light mono rig for tight-line nymphing small streams: 480 inches of .009 Maxima Chameleon, 24 inches of white Cortland indicator mono, then an 18 inch Cortland bi-color sighter. A 2 mm tippet ring below the sighter holds 36 inches of 5X fluorocarbon to a tungsten jig nymph. The thin butt sags very little, so small, light flies stay in contact.

The knots

  • Blood knot · 5 turns×2
    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.

  • Improved clinch knot · 5 turns×3
    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

Use it in pocket water and short runs where you can stand close. Cast the jig upstream on a short line, lift the rod so the mono stays off the water, and lead the fly downstream at about the speed of the current. Watch the white and bi-color sections above the surface and set on any pause or twitch. Change the bead weight to match the depth.

Thin mono rigs tangle when cast fast. Slow down, open the loop and let the jig pull the rig out, and rebuild the 5X tippet off the ring when it gets short.

Common questions

  • Why is the butt so thin?

    The 480 inches of .009 Chameleon weighs and sags very little, so a light jig stays in direct contact and the sighter shows the smallest stop in the drift.

  • What do the white and bi-color sections do?

    They are the sighter. The white piece is easy to see in flat light and the bi-color piece shows depth and the take. Keep both above the water.

  • Do I need split shot or an indicator?

    No. The tungsten jig carries the weight and you read the take on the sighter. If the fly is not reaching bottom, tie on a heavier bead.

  • What is the tippet ring for?

    The 2 mm ring lets you replace the 5X fluorocarbon tippet without cutting the sighter shorter.

  • 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.
