Do not borrow species or access expectations from far downstream Connecticut River sections. This is an upper-river planning page near Pittsburg.
The Connecticut River below Indian Stream is an upper Connecticut River reach near Pittsburg, New Hampshire. For fly anglers, the useful framing is a northern coldwater trout reach with rules, access, and conditions that can differ from other Connecticut River sections.
Before fishing, confirm the current NH Fish and Game freshwater rules, use the USGS below-Indian-Stream gauge, and verify public access. This page intentionally avoids broad lower-river species claims and focuses on what an angler can responsibly check for this reach.
