About Squannacook River
A 16-mile cold-water freestone stream in northern Massachusetts that drains a forested, spring-fed watershed through Groton before joining the Nashua River. It offers exceptional diversity — fast freestone runs, deep pools, and spring-fed tributaries filled with native brook trout — and supports naturally reproducing trout populations that survive year-round in its cold water. Often overlooked by out-of-state anglers, it is a reliable four-season fishery with both stocked and wild fish throughout its length.
Regulations
Standard Massachusetts trout regulations apply: season opens April 1. MassWildlife stocks brown, rainbow, and brook trout each spring and fall; many cold tributaries hold self-sustaining wild brook trout year-round. No designated fly-only or mandatory C&R sections on the main stem.
