Imitating the Nymph
In case you missed it, the large Salmonfly nymphs crawl out of the water on the banks to hatch. They don't
hatch in the water. They sometimes choose large boulders that protrude above the water line to crawl out
on to hatch.
During the hatch the trout are used to seeing the large nymphs move across the bottom to the banks. If
you have a clear area in which to do so, we suggest that you walk along the banks and present the nymph
imitation very close to the bank using very short cast in an upstream direction. This way you can cover a lot
of water without spooking the trout holding near the banks feeding on the Salmonfly nymphs.
Make sure you bring the nymph imitation all the way back to the bank. There isn’t much need to be casting
far out into the stream. Time is spent more productively presenting the nymph close to the banks where the
trout are obviously waiting on the nymphs to crawl out of the water.
If the banks are lined with trees or bushes and you must wade, we suggest you wade in the middle area so
that you can reach both banks. If the stream is too wide to do that, you should choose what you think is the
best bank and wade just far enough away from it to cover it well. Again, the idea is to keep the fly near the
bank. That's where the trout are used to seeing most terrestrial insects.
It's much better to make a lot of short cast with get short drifts than to try to make long cast and get a long
