Baetis

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

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.

Hello Jason,

I stumbled onto your Instagram page by accident. Nice little streams. The initial picture surely looks like Paradise Valley near Livingston.

Thanks. I've been meaning to update my Instagram with some more pictures but it just hasn't been a priority.

I'll send you a private message about this creek -- it's not Paradise Valley.
