There isn’t a better feeling than to catch a trophy trout while basking under the gentle heat of the morning sun fly fishing in one the best streams or stillwaters in your area. It’s one of those moments that your heart swells with pride even if no one’s around to see it except Mother Nature. Among other factors, the right choice of nymphs is one of the determinants in making this happy fly fishing dream a reality.

Dave Hughes is an expert on fly fishing and when he gives advice and shares his tactics on using nymphs for streams and stillwaters you’ll want to listen. He is an author of more than 20 books about fly fishing for trout, including his latest book titled Nymphs for Streams and Stillwaters. He is also the editor of Fly Fishing and Tying Journal. He was the founding president of Oregon Trout in 1983 and has been awarded with a life membership in the Federation of Fly Fishers in 1985. He is also an accomplished amateur aquatic entomologist. Through his very busy schedule, he still finds time to go fly fishing time and again, but he says, “It’s never enough.”

Insects that have a larvae and pupae stage are insects that have complete metamorphosis, Dave says that nymphs don’t have a complete metamorphosis. “They go right straight from the nymph stage to the adult.” He added that nymphs look very similar to the adult. “You add wings, you’ve got the adults essentially.” Dave sites mayflies and stoneflies as examples.

In fly fishing terms, Dave defines nymphs as fly patterns that represent the larval, pupal, or the nymph stage of an insect or creature that goes underwater. To cut it short, Ed Angle puts it as “nymph imitation”. “They can represent leeches, slugs, scuttle bugs, and aquatic scuttle bugs,” commented Dave.

According to Dave, you can group your nymphs into three boxes: A box for searching nymphs, a box for imitating nymphs for moving water, and a box for imitating nymphs for stillwater. He explains that the purpose of having the third box is because “stillwater insects are a bit different from most moving water insects.”

Although nymphs are predominantly for trout fishing, Dave says that they can also be extremely effective for small mouth bass. “I went small mouth fishing and the fish just hammered them. They really were more effective than the streamers I typically use or the poppers,” he says.

As an observation from his past fly-fishing experiences, he says that the water temperature does not necessarily affect what nymph he will use. “I don’t think your nymph selection is based on water temperature. It’s more based on what I collect from the stream and making sure I have something on there that’s small. What I find in the stream would affect it.” He says that if the temperature is cold, he would make sure that he has a very small fly on. A size 14, 16, or 18 combination would be ideal.

According to Dave, under a natural drift, a nymph fly that has a flashy material can outperform one that doesn’t. “The reason is that a lot of insects, when they get ready to emerge, they exude nitrogen between the exoskeleton of the pupa on the outside, the nymph on the outside, and the adult which is already on the inside. So there’s some natural brightness on most of these insects that come up,” he explains. “The brightness attracts the fish’s attention.”

The most critical mistake an average angler has to make when fishing nymphs in streams, according to Dave, is not getting deep enough. “If you’re not getting your nymph on the bottom or within a few inches of it, then that’s the biggest mistake because you won’t be catching fish,” he says.

Western lakes and reservoirs have large chirominids, Callibeatis, scuds, damsels, and midges which are essentially the bread and butter nymphs for stillwaters. “All the literature on midge fishing comes out of Canada because the midges are bigger up there; if they’re bigger, they are easier to fish and more important,” Dave says.

However, he says, “What you’ve got to realize is that the insects are pretty much the same in all the lakes, but they are not all the same sizes. If you reduce the sizes of what those folks are talking about, it’s going to work for you very well.” Dave usually takes the stuff that they pioneered in Canada but he uses smaller nymphs instead.

During springtime when he doesn’t observe any insect or fish activities on stillwater, Dave fishes what he calls “the bottom of the shallows. “You go into shallow water because it warms up first. The bottom of the shallows are going to be anywhere from maybe 5 to 10 feet down or depending on the depth of your water. Whatever that depth is, I’m going to want my fly suspended one or two feet above that bottom.”
