Fly Tying The DC Leech

HOOK: #4-8 4XL streamer, Tiemco #9395.
THREAD: Black 50-denier UTC GSP.
WEIGHT: .010" wire.
BODY: Fiery brown or black Angora goat hair.
FLASH: Red Krystal Flash.

DC Leech Step 1 of 5

With the hook in the vise, bend the hook shank slightly upward approximately ¼ inch behind the hook eye. Apply eight or ten wraps of .010" wire on the bent portion, leaving a little space between the wire and hook eye to finish the head. Anchor the wire with a few thread wraps, finishing immediately behind the wire.

DC Leech Step 2 of 5

Twist a half-dollar-size wad of goat hair into a tight rope between the thumbs and forefingers of both hands. Maintaining a good grip with one hand, attach it to the hook shank with several tight thread wraps. Double a single strand of red Krystal Flash around the tying thread and attach it at the goat hair tie-in point.

DC Leech Step 3 of 5

Clip the Krystal Flash just short of the tail length. Fold the forward portion of goat hair toward the rear of the hook and secure it at the original tie-in point. Add a small drop of Super Glue at the wire/material junction to keep the body from rolling on the hook shank.

DC Leech Step 4 of 5

Dub a small amount of goat hair to the thread and cover the wire with a nicely tapered application of dubbing. Crisscross this area with several tight thread wraps to form a compact underbody.

DC Leech Step 5 of 5

Coat the thread with dubbing wax and apply some goat hair to form a dubbing noodle. Wrap the noodle to form the shaggy overbody. Whip-finish and cement the head. Next, tease out the front portion of the fly with a strip of Velcro. Meld the entire body together by combing to the rear with a dubbing brush.

A'Šfew seasons ago I signed on for fill-in guide work at a private ranch near Kremmling, Colorado. The ranch property includes 2 miles of the Middle Park section of the Colorado River, as well as a 2-acre stock pond that interrupts the flow of a tiny feeder stream and offers refuge to oversize browns, cuttbows, and brook trout.

During one of my guiding days, a client who had taken a college entomology course suggested we take a break to conduct a little in-stream research. When we lifted a vegetation mat from the water, large brown leeches dropped out in surprising numbers. Further investigation of submerged rocks and debris revealed countless gelatinous larval cocoons — each containing a minute, writhing, wormlike infant leech — the progeny of hermaphroditic annelid parents.

The trout in this pond devoured my simple, easy-to-tie Angora goat leech pattern, and the DC Leech has since become a standard fly for local guides here and elsewhere on Rocky Mountain lakes and rivers.

My own river leech-fishing enlightenment occurred on the Grey Reef section of Wyoming's North Platte River. We were drifting through the public water just downstream from Lusby Landing when I hooked and netted a good-size rainbow. A stomach sample revealed several undigested brown leeches, along with the anticipated mix of midge pupae and larvae, Baetis nymphs, and scuds. The sample showed the importance of leeches in a trout diet, reaffirming the value of leech imitations as part of a well-rounded fly box.

Dead-drifting this fly below a strike indicator has also produced large trout on Colorado's White and Yampa rivers, and Montana's Bighorn.

Putting it to Work

The DC Leech's 4XL hook allows you to position the hook point well back in the pattern profile. I've found that on ponds and lakes, in particular, fish sometimes short-strike this fly. The longer shank produces more hookups.

When short strikes occur, resist the urge to lift the fly from the water and cast again. Instead, allow the fly to sink slowly for several seconds, as if injured, and then give it another short strip or two. Fish often return to the fly and hit it again.

In the same vein, don't strike by raising the rod tip, which can also move the fly out of the strike zone. A short strip-strike keeps the fly in close proximity to the first hit, increasing your odds of ultimately connecting.

On stillwaters, a slow strip-and-pause retrieve usually entices the most strikes. Fish the DC Leech on a floating line or with a clear sinking line. The small amount of weight behind the fly's head helps it undulate in the water. Use a non-slip loop knot to attach the fly to your tippet, further enhancing its animated leechlike movements.

Leeches are most active at low light, during early morning and late evening. At these times, fish often grocery shop along the edges of shallow, weeded, littoral zones of lakes and ponds. To maximize your fish-catching opportunities, be stealthy and work these areas with a systematic, fan-shaped casting pattern.

Tying Tips

The DC Leech is a quick tie once you've gotten the hang of it. Use a half-dollar-size wad of fiery brown or black Angora goat hair dubbing and twist it into a tight rope — of equal proportions — between the thumbs and forefingers of both hands.

Maintaining a good grip on the twisted hair rope with one hand, attach it to the hook shank behind the wire wraps with several tight thread wraps. This anchors any loose material into a manageable state.

I use UTC Ultra GSP 50-denier fly-tying thread for this pattern. The gel-spun thread makes it possible to exert a tremendous amount of pressure on the wraps without breaking the thread.

Once you've secured the dubbing rope with tight thread wraps, apply a small drop of Zap-A-Gap glue to the junction to prevent the body from rotating on the hook shank.

Angora goat hair is very slick, or "greasy," and it takes some effort to get it to stick to the thread. I use generous amounts of dubbing wax.

After wrapping the body, use Velcro hook material to tease out fibers from the goat-hair dubbing, and then sweep and meld the entire body together with a dubbing brush.

Natural leeches come in a variety of colors. In fact, most of them are not one solid color but mottled natural olive, brown, tan, and black. For a variegated look, simply hand-mix two or three colors of Angora without pre-blending. Blend the hair in a small coffee grinder for more monochromatic color schemes.
