Tying for the Way You Actually Fish

Lesson: Building a Small, Durable Box for Local Streams

okay. we've done a bunch of individual patterns now. hare's ear, pheasant tail, elk hair caddis, the whole lineup. this lesson is different — we're not tying a new fly, we're talking about what actually goes in your box when you head up the canyon or down to the provo for a morning.

i see people show up to a stream with a giant fly box, four rows deep, every color of dubbing they've ever bought. it's not necessary. actually i'd argue it works against you. you end up standing in the water flipping through compartments instead of fishing.

what a small box actually needs

here's my real answer, based on what i tie and what i've caught fish on around here for years:

  • hare's ear nymph, sizes 14 and 16. this is your workhorse. buggy, sinks fine, looks like a dozen different bugs at once.
  • pheasant tail nymph, sizes 16 and 18. thinner profile, good for when the water's a little clearer or the fish have seen a lot of hare's ears already.
  • a beadhead version of one of the above, at least a few, for faster or deeper water.
  • elk hair caddis, sizes 14 and 16, maybe an 18 if you tie them small. your dry fly. holds up in riffles, which is the whole point of that fly.
  • something with a little flash or a slightly different silhouette as a change-up. i keep a couple of beadhead pheasant tails with a wire rib for this. nothing exotic, just something different enough to show the fish if the standard stuff isn't working.

that's it. that's the box. maybe fifteen to twenty flies total if you tie a couple sizes of each. technically you could fish an entire season on freestone water in utah county with just those five patterns and never feel undergunned.

why small is actually the strategy

i've said this before in this course and i'll say it again because it's the whole reason this module exists: fast freestone water doesn't give the trout much time to inspect your fly. they're committing fast or not at all. what matters way more than having the exact right bug is (1) getting the fly down to where the fish are and (2) having a fly that survives getting slammed through a riffle without falling apart.

that second one is why this lesson is about durability, not variety. a fly that looks great in your hand and unravels after two fish is worse than useless out here. it's actually a liability, because you'll keep fishing a broken fly for another ten minutes before you notice, and that's ten minutes you're not catching anything.

building for durability, practically

a few things that actually matter more than which materials you buy:

whip finish every fly, don't skip it. if you've been tying half-hitches to save time, stop. a proper whip finish under the head is the difference between a fly that survives a season and one that comes apart in the current.

check your thread tension on the last few wraps. most unraveling happens right at the head, where people get lazy because they think the fly's basically done. it's not done until the knot's tied and it's tied right.

don't overdress it. more material wrapped on doesn't mean more durable, it means bulkier and less likely to sink right. i went through this myself early on — my first flies all had these fat little heads because i thought more thread wraps meant more secure. my wife found one in a junk drawer two years later and asked me if it was a cat toy. it wasn't durability, it was just extra bulk that didn't need to be there.

dry your flies before you box them up. a wet fly sitting in a compartment for a week starts to rust at the hook point and the material mats down. takes thirty seconds to lay them out on a towel after a trip.

the scout troop flies

a guy in my ward found out i tied and asked if i could put together a few flies for his son's scout thing. i made a dozen — mostly hare's ears and a couple caddis, nothing fancy — and then i spent about ten minutes explaining barbless hooks and hook safety to a bunch of twelve year olds who mostly wanted to go fish. looking back i should've just handed over the box and said good luck. sometimes the instruction gets in the way of just letting people go use the thing. i think about that a fair amount when i'm teaching this class, honestly.

that said — if you're building flies for someone else, or for kids, do actually mention the hook point. it's not a lecture, it's one sentence: watch the barb, it's sharp, don't stick yourself pulling it out of the box. that one's worth saying every time.

before next time

pull together your own small box using the list above — doesn't have to be tied yet, even just sorting what you've already made into "keep," "retie," and "actually this one's for the junk drawer." we'll build off whatever gaps you find next lesson.
