High elevations: 53 – 58 degrees

Current Conditions

Ida came through mid week and dumped a ton of rain so streams are too high to fish right now. However, all that rain coupled with mild temperatures has dropped water temperatures a bunch.

Water is high everywhere but the North Carolina side of the park is in a little better shape. It will just take a couple of days to drop to workable levels. Across the board, expect fishing conditions to improve greatly by the latter part of the weekend.

Projected Conditions

Once water drops, we should be looking at a great week ahead! As mentioned above, water temperatures have dropped significantly which should have lower elevation streams turning on. Temperatures are expected to remain mild through the week. I’m sure we’ll have at least a couple more bouts with hot weather in the coming weeks but for now, enjoy this little fall teaser!

Tips

Over the next day or two, I’d stay off the streams unless you really know your way around Smokies streams. High water is dangerous and there will be a very limited amount of fishable water. As water continues to drop, use caution and focus flatter, “pooly” parts of the stream.

It will be mostly nymphing in the coming days… fish them heavy and deep. Check out Fishing High Water for a few tips. By Sunday or Monday we should begin seeing topwater activity pick up again.

Hatches/Fly Suggestions

While water is high, I’d focus mostly on nymphs. I’d fish a pair and try to diversify them. Have one bright and one drab or one big and the other small. Don’t be afraid to experiment. In addition to the standard nymphs mentioned below, I like worm patterns and big, rubber-legged stoneflies in higher water.

Once the water drops back to normal, you’ll still do a lot of pocket water fishing in the coming weeks. For that, it’s tough to beat a dry fly/dropper rig. For a dry fly, I like anything that floats well and that I can see, probably in the size #16-12 range. I prefer something yellow and probably foam. However, we will soon be transitioning into tans and oranges. But most any attractor will get you through most situations. Parachute Adams, Parachute Hares Ears, Thunderheads, Adams Wulffs and Royal Wulffs always do pretty well.

But as mentioned, you’ll want to be sure to have some dry flies in yellow, and soon orange and tan to best match hatching insects. A yellow, orange or tan Neversink in #16 – 14 is a staple for me. So is a yellow or orange Stimulator. I’d also carry some tan Elk Hair Caddis in #16-14. For nymphs, try Hares Ears, Pheasant Tails, Copper Johns, Tellico Nymphs and a favorite this time of year… George Nymphs.

Summer is winding down but terrestrials will still be an important food source for the next 6 weeks or so. Fish will continue feeding on ants and beetles. Inchworms are abundant as well and a Green Weenie can be a killer this time of year. It’s a great fly to drop off a dry fly.

Featured Fly

Isonychia nymphs are very active this time of year. While there are a number of specific Isonychia patterns, the George Nymph has always been one of my best imitations. So, while it’s a great generic nymph all year, I think the George Nymph is at its best in August and September!

Flies: Isonychias

The mayfly with the funny name is one worth knowing when it comes to fishing in the late summer and early fall. Actually, all mayflies have funny names, but most, over the years, have become known by some common name such as Light Cahill, Sulfur, March Brown, or Quill Gordon. But the Isonychia still proudly boasts its Latin name. Sure, there are those who might refer to them as Mahogany Duns, Slate Drakes, or even Leadwing Coachman, but none of those names ever stuck.

Probably the main reason is that those common names refer more to this insect in its adult stage, but to the trout (and trout fisherman), the nymph is by far the most important stage of this insect’s life. Isonychias, or Iso’s as some call them, don’t behave like most other mayflies when they hatch. Most mayflies will emerge to the surface and hatch in the water near the surface film. After hatching, they are often on the surface for a small amount of time, allowing their wings to dry before they fly off. This leaves most mayfly adults vulnerable to hungry trout and is the stage of the lifecycle that many dry flies represent.

But Iso’s behave more like a stonefly. The nymphs swim to rocks or woody debris and hatch out of the water. The trout never get a shot at the adult until it later returns to lay eggs. Take a closer look at exposed rocks in or around the stream this time of year and you’ll likely see some of their empty shucks.

In the Smokies, they typically hatch from August through October with peak emergence in September. If you want to try your luck imitating them with dry flies, try a dark bodied parachute in size #14-12. The body color will typically be anything from a deep mahogany to dark grey or even black. A good ol’ Parachute Adams is probably as effective as anything. When they return to the water to lay eggs (known as the spinner stage), their body color is more orange or rusty.

However, as mentioned above, the nymph is what you should be most concerned with. Also in sizes #14-12, the nymph is slender with a dark brown to black body. It has a very distinct white stripe down the back. You will sometimes find specific Isonychia nymph patterns but they are imitated well with common patterns. Prince nymphs or Zug Bugs are a couple of favorites. The late Eddy George was a well-known and highly respected fisherman and fly tyer in this area. He is probably best known for the George Nymph, a fly that I regularly tie and fish in the Smokies. Many people speculate what this fly might represent. With its slender, dark body and white poly-yarn back, it’s incredibly effective during Isonychia time!

Dark soft-hackled wet flies are very productive, too, as Isonychias are active swimmers and tend to be most active in the mornings and evenings. Any time of day is a good time to drop one of the above fly patterns off a dry fly. Early and late in the day, try fishing with one or a pair of these nymphs. Vary your typical dead-drift presentation to offer the occasional twitch or even swing. Check out the Active Nymphing article in this newsletter for more on that presentation.
