“What are the best soft hackles (or wet flies) for fishing the Hendrickson hatch?” is one of those questions I get a lot this time of year. As always, the best flies are the ones in which you have the most confidence. I should also make this clarification: technically, with Hendricksons you’re fishing wet flies under the hatch. On the Farmington River, prime time for swinging Hendrickson wets is generally in the 11 am-to-3 pm window. Every day is different. Once you see duns on the water, and trout snapping at them, the wet fly game is all but over. But if you want to catch more trout, you should be swinging wets in this pre-hatch time frame. (Of course, you’re fishing a team of three wets. Here’s how to build a wet fly leader.) And so, in no particular order, these are some of my favorite Hendrickson wet fly and soft-hackled patterns.
Monday’s Hendrickson hatch in the lower end of the Permanent TMA was a solid 8 out of 10. (The pre-hatch bite was slow, and the duration of the duns-on-the-surface feeding frenzy was brief, otherwise I would have graded it higher.) So I headed back yesterday to see what secrets the river would reveal. Crowds continue to be a factor; if you’re looking for solitude within the Permanent TMA, you will be disappointed. I chatted up my new buddies from yesterday, Andy and Bob, who were likewise back for more, and when some water opened up — people do leave — I jumped on it. Conditions were as nice as you could hope for, with a clear flow of 275cfs and hazy sun and far less wind than Monday.
The section I fished was perfect wet fly water: moving at a brisk pace, mottled, multiple current seams. Wet fly continues to be a highly productive method for fishing under the Hendrickson hatch, especially when it appears as though nothing is going on. While many other anglers are lounging on the river bank, or standing mid-stream like statues, I am working the water with a team of three wet flies. Wet fly anglers will always discover that something is afoot subsurface before dry fly anglers, and that was proved again yesterday. Around 1pm, I had an intense flurry of activity for 15 minutes, including hits on four consecutive casts. Then the action slowed.
Then, just like that, it was over. I added a shot above my middle dropper to see if I could tight line nymph up some trout, but they weren’t having it. (This is something I teach my clients: when you walk into a pool, you simply don’t know what’s been happening. The trout may have had the feed bags on for the previous hour, and now they’re simply just done.) So I got out of the river to warm up a bit. With the pool rested and my legs a little less frozen, I waded back in around 2pm.
Since I was hoping to find the fish that were already looking up, I switched out the bead head on point for a fly I’d never fished before. It was the Old Blue Dun, one of Leisenring’s favorite twelve. I’d always thought it would make a fine Hendrickson, and since to this point I’d seen more olives in the air than Hendricksons, it seemed like a proper why not? moment. It was a good decision, as a rugby ball-shaped survivor strain brown hammered the fly on the dangle.
On Monday, the Hendrickson duns were on the surface thick by 3pm. That was not the case yesterday; we probably had about two-thirds less mayflies. Still, I brought several trout to net on Hendrickson Usuals and Comparaduns, two patterns I like in choppy water as they provide a good profile when viewed from below. I had to be off the water by 3:30, so reluctantly, I pulled myself away from pleasure and headed off toward responsibility.
