Tying for the Way You Actually Fish
Lesson: Match the Hatch Is Oversold on Freestone Water
okay. new module. we're not learning a new fly tonight — we're stepping back and talking about how to actually pick what to tie, because i think a lot of people get stuck buying or tying flies based on a system that doesn't really apply to the water most of us fish around here.
so. match the hatch. if you've read anything about fly fishing you've run into this idea — figure out exactly what bug is on the water, tie or buy something that looks just like it, present it well, catch fish. and on some water that's exactly right. slow, clear, technical water where trout get a long look at your fly and have all day to decide it's fake. spring creeks, tailwaters with glassy pools, that kind of thing.
that is not what we've got up american fork canyon. or on most of the freestone streams in utah county.
freestone water is fast. it drops off the mountain, it's got riffles and pocket water and broken current, and the trout in it are not getting a long, leisurely look at anything. a fish in a riffle has maybe half a second to decide whether that thing tumbling past is food. it's not comparing your fly's wing color to the naturals hatching that day. it's making a snap judgment based on size, silhouette, and whether it's moving through the water the way food moves.
so my actual opinion, and i know some people disagree with this pretty strongly: on fast local water, presentation and getting the fly down to where the fish are beats exact imitation nine times out of ten. i'd rather have the right size and the right drift than the right species.
what this means for your fly box
practically, it means you don't need six different mayfly patterns in slightly different shades of tan. you need:
- a couple of general nymphs in the right size range (this is why we spent so much time on the hare's ear and pheasant tail — they're not imitating one bug, they're imitating "bug")
- something buggy and dark for when the water's off-color
- a caddis dry that rides low and durable
- and the confidence to fish what's in your box instead of standing on the bank trying to identify the exact insect
that last part is the real skill. not entomology. drift.
a quick honest aside
i'll be straight with you — i'm not an entomologist. i can tell you the difference between a mayfly, a caddis, and a stonefly by looking at one, and i know roughly what stage of their life cycle turns them into food for a trout. but if you ask me to walk you through the full life cycle of a pmd hatch i'm going to get fuzzy pretty fast, and i'd rather tell you that than pretend otherwise.
which actually gets at something i think about a lot. i was at the fly shop a while back and got into it with a guy about whether a certain dubbing was actually synthetic or natural. i was right, technically — it was a synthetic blend marketed like it was natural fur. but i corrected him kind of firmly, in front of other people, over something that honestly didn't matter for how the fly fishes. he was polite about it. i drove home replaying the whole thing and deciding i probably didn't need to have said anything at all.
that's the trap with match-the-hatch thinking too. it turns fishing into a trivia contest. you can be technically right about the bug and still not catch anything, because you weren't paying attention to your drift.
how to actually pick a fly on the stream
here's the process i actually use, no entomology degree required:
- flip a rock or look at the bank for size and general color — are the bugs around here small and dark, or bigger and lighter. that's it. that's the level of detail you need.
- match that size roughly. a size 14 versus a size 18 matters more than the exact shade of brown.
- pick your fly based on the water, not the bug. riffle and pocket water — go with something that sinks and holds together, like the beadhead nymphs we tied. slower flat water — dry fly, and get the drift right.
- fish it with confidence. the flies in your box right now, from this course, cover almost everything you'll run into on a freestone stream. trust the box.
a caution, since we're talking about wading around to look at bugs
if you're flipping rocks to check what's living under them, watch your footing. freestone streambeds are round, wet rocks, and it's easy to get so focused on looking down that you don't notice the current pulling at your legs. take it slow, especially early season when the water's higher and colder from runoff.
before next time
think back through your fly box and notice how much of it is really "general bug shape in the right size" versus something you bought because it looked exactly like a photo in a magazine. next lesson we'll start building flies specifically with that durability-over-looks idea in mind.
