I recently received this question via email from one of our readers and thought it would make a nice followup blog post.

Hi Matt,

 I just read this article on Callibaetis nymphs, and I have a question.  Don’t nymphs in stillwaters usually rise fairly straight up from the bottom?  How can I simulate that with nymph flies?  No worries on moving water, but I’m confused with this one.

Thanks so much.



Thanks for reading and reaching out!  Great question. I’d say that when they are emerging, Callibaetis nymphs will rise up at a semi-steep angle, but not completely vertically.  That said, the rising motion can definitely be a trigger to get the fish to eat.  Let me offer you 3 or 4 ways that you might accomplish this…

 1:  Floating fly line, long leader, and a weighted nymph.  Cast out and let the nymph sink down as deep as you think it needs to.  Maybe the top of the weeds if the area is shallow enough.  When you start your retrieve, the fly will naturally rise up at an angle following the leader up to the surface where the line floats.  When you’ve retrieved an amount of line about the equivalent to your leader length, stop, and let the fly sink back down again.  Repeat.  To detect takes, you need to watch the end of the floating fly line.  If it twitches, dives etc, set the hook.  You may not feel the take because the line isn’t drawing a straight line from you to the fly.  Pay attention while the fly is sinking back down too.  Sometimes that is the trigger!  It’s important that your leader not have coils in it so it is as straight a connection tot he fly as possible.  I’ve also incorporated a tiny strike indicator into this method at times, especially if there is a chop on the water that obscures my view of the tip of the flyline.  Foam pinch-ons work great for this.  Last tip, flourocarbon leaders sink faster than nylon mono leaders.

 2:  Intermediate sinking tip line (or intermediate sinking poly leader) and weighted or unweighted fly.  Basically this is the same approach as above, but with a sink tip to get the fly deeper initially.  If you are in say 10 to 15+ feet of water, the leader and weighted fly alone will be annoying or impossible to get that deep, especially if there is any wind.  Let it sink and then retrieve it up as before.  Then repeat.  Watch the color change of the line or where it enters the water for the take.  Also feel fro the grab.

 3:  Full sinking intermediate line and unweighted nymph. This line system draws the fly through the water horizontally for the most part and is my #1 way of searching for fish before, during, and after a Callibaetis hatch if I don’t see them rising in a way that allows me to effectively target them on the surface.  But, at the very end of the retrieve, when the fly is deep, and you begin stripping the last few yards of line up toward the surface, the fly does rise at an angle.  A lot of folks just pick up and cast again.  This is a mistake.  UK stillwater experts preach about “fishing the hang” at the end of a retrieve.  Focus on the last part of that rising retrieve.  Pause it, sink it, and raise it again.  Don’t strip the fly right to the rod tip, but leave a bit of line out and slowly raise the rod tip itself to make the fly ascend.  If you start getting fish only when the fly is rising, maybe you need to switch to one of the first 2 methods!

Take Care and Fish On,
