I spent a couple of hours on the Souhegan early on Friday morning. No trout pictures unfortunately; but I did catch two small (native?) brookies about 6-7" on the fly shown in one of the images below. It's a peacock herl-body parachute designed to be bright so I can see it. The white puffy stuff in the parachute picture is the reflection of the clouds.
The black and fl. green dragonfly is a variety that I have only seen on a couple of my local streams (the Souhegan and especially on the Squannacock). The one pictured here was the only specimen I saw Friday.
