Matching the Hatch

by Fred Rowe, Sierra Bright Dot

It’s both the holy grail of fly fishing and it’s a two-part solution. First, you need to know what the fish is feeding on. Second, you need to have an imitation of the insect that is perfect.

Hatches are seasonal and looked forward to with much anticipation by fly fishers. Here in the Eastern Sierra blue wing olives (BWO) are the first hatch of the season starting in early February. That hatch is followed by caddis, pale morning duns (PMD), little yellow stones, callibaetis, and summer hopper hatches. In the fall fly fishers look for the October caddis, the biggest caddis in the Sierra, and tricorythodes mayflies (Tricos), the smallest mayfly in the Sierra.

Once you have identified the hatch you need an imitation that is a perfect match of the insect. The fly pattern needs to incorporate the size, shape and color of the natural, and needs to be fished the way the insect behaves. Some patterns can be bought off the shelf but other patterns can only be duplicated by tying your own flies.

I got into the fly-fishing industry as a fly tier. I’ve gotten good at tying exact imitations of other fly fishers fly patterns and imitating the insects found in the waters of the Eastern Sierra. I’ve also fished the major hatches in the Sierra with reliable success. I’ve never seen the October caddis hatch in big enough numbers to have the trout feed selectively on them. I’ve fished the Trico hatch a few times with mixed results. Recently I was tapped for my fly tying skills by  a local fly fisher as he was looking for someone to tie a fly pattern that was not available at any of the Eastern Sierra tackle stores.

He had me look at some insects from a stomach pump sample and I recognized them instantly as Trico spinners. I told him I could tie up an imitation if I had a small enough hook. I figured that the natural was a size 28 or 30. The smallest dry fly hook I have is a size 24. There might be a smaller hook, but a size 24 is small.

As you can see in the photo, a size 24 Trico spinner fly tucked in with the naturals from a stomach sample shows that the fly pattern is bigger than the naturals.

I tied up some Trico spinners on the size 24 hooks and took them to the water to test them out. I attached a three-foot section of 6X tippet to my leader and tied a spinner on with a turle knot. I watched several trout rise to insects on the water that were so small I could not see them. I cast over the fish with the confidence that I had the right fly. Cast after cast and the trout were not interested in my fly pattern. Several trout rose to the fly but would not take it off the surface.

Two variations of a Trico spinners tied up on a size 24 dry fly hook and an equivalent size 28 nymph hook.

I tried a Hot Creek trick I knew about getting a drag free drift. I cast the fly such that it landed in a puddle of tippet. This allowed the fly to naturally drift down stream. This resulted in several hits and a couple of eight to ten-inch brown trout being fooled. A stomach sample from the brown showed that the naturals were a couple of sizes smaller than my pattern.

A ten-inch brown trout that was fooled by a size 24 Trico spinner that was two sizes too big to match the naturals on the water.

My pattern was close, but it was not perfect so I’m back to the fly-tying table to try and come up with a pattern that is a perfect match. I tied up a few spinners on a scud hook, smallest hook I own, to see if I could get the size right and I need to take them to the water to give them a try.

I only got half of the formula for matching the hatch correct. My insect identifying skills were correct. My fly pattern is correct in shape and color. Size is off by 40 to 60% and is responsible for the fly not being the right fly.

This is the joy of being a fly fisher – fly tier in the Eastern Sierra. I will continue to return to the water until I can get the formula correct. When I do every trout in the creek will rise to take my Trico spinner off the surface.

I went up to 12,500 at Ski Apache in Ruidoso, N.M. My head nearly exploded.

Yep. I feel so amazing in high altitudes.

Very well done. I’ve never been over 12,000 and that just about ended me.

Why cant we post pics on this site anymore?

Been there a couple of times. Better than Whitney

Congratulations!

BEAUTIFUL

I like those kinds of places. You can get a natural high. I think I've been there before. Hope to get back there soon. <3

Badassery

Great photo! Looking great @ 14k+ ❤️

Definitely has a great view

...would have done it 40 years ago

How come females look so good after bagging a peak, but guys look tuckered out?

Mammoth parade starts at 11:00

Always head up to Whites Mountain for Ancient Bristol Cone Forest.

Awesome

Been up there.

My friend Jack McBroom from Hemet climbed the highest 14 peaks on California in about four and a half days. Not sure that is still the record but I know it was for awhile. Sports Illustrated did an article about him.

Comment on Facebook We love seeing folks...

Thank you for doing your part. Just get used to it, we're in it for the long haul. It doesn't hurt to err on the side of caution. I would.

Best little town in the West. I hope you're all hanging in there. Stay safe so I can visit this fall!

I love Bishop because of it’s proximity to Death Valley and the Sierras. On a motorcycle!

A family hiking out in the mountains on a warm summer day..... with masks on. This has to be the stupidest photo on FB all day.

Ah, wearing a mask outdoors in the Sierra's. They're obeying their globalist masters. Good little sheep.

What a sad picture that this family appears to be out in the countryside ,away from people, wearing a mask..

You don’t need masks if you are outside hiking with your family.

Makes no sense to go up to the mountains for fresh mountain air just to breathe in your own co2

The masks with the exhale feature on it does not block your droplets from exiting and infecting the people around you.

That is not the Bishop I grew up in. We didn’t live in fear‼️ Bishop as lost it’s way. Sad fir a beautiful area ,

What time does the 4th of July parade start ?

masks are nonsense,, please stop

I really miss living there. Be back soon.

Enough of this bs. No way I would go hiking in the mtns and wear a mask. Just may as well stay in the cesspool known as LA County and breathe the air here with a mask on.

Hopefully the mask wearing works, cause the social distancing and all the sanitizing isn’t...

Wearing masks in fresh mountain air & sunshine. Just can't fix stupid.

More crying 😢 about wearing a mask. Pitiful little babies!!

Guess I won’t go this year👎

Jeeping this 4th of July!

More sheep

Looking good!

Yellow star,mask..same thing advocated by the same types of people.

No more masks.

Missing hometown

Lived in Bishop early 90's. Can't believe what houses cost there now!!!
