The Natchaug River is one of Connecticut's hidden gems for trout fishing, flowing through the northeastern portion of the state from its formation at the convergence of the Still River and Bigelow Brook near Eastford down to Mansfield Hollow Lake. Despite being one of the least fished but most heavily stocked rivers in Connecticut, the Natchaug offers exceptional trout fishing opportunities in a beautiful, evergreen-lined setting. The name "Natchaug" comes from the Wabbaquasset Native American language, meaning "Land between the rivers," referring to its two main tributaries. This freestone stream flows for its entire length as a designated Trophy Trout Stream by Connecticut's DEP, featuring excellent public access through conservation easements established by the former Natchaug Chapter of Trout Unlimited.
