Hex Mayflies
Hexagenia limbata

The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

I caught a nice brookie a few weeks earlier in this pool at the junction of a split channel in the stream. The huge fallen tree is great cover.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Nymphed hard for the first 4 hours and only resulted in the lone smalmouth. Wind made upstream cast very difficult and flow required 5-8 BB shot to get to the bottom (on top of heavily weighted nymphs).

Mayflies started to get going around 1900 and the frustration began. This wasn't the typical frustration of not being able to get fish to take but instead seeing so many bugs on the water and absolutly nothing working them. Finally around 2015 a few fish started to roll on some duns and I was able to hook and land a very fat and fiest bow before losing light to wade by.
Overall a beautiful but very disappointing day.
Forecast is for rain and an east wind on the Raritan bay tomorrow hopefully the rockfish will be cooperative.
