Rapid River (Maine)

The Rapid River is a short, swift-flowing river located in Oxford County, Maine, USA. It connects Umbagog Lake, the source of the Androscoggin River, to Lower Richardson Lake. Known for its exceptionally clear and cold water, the Rapid River is a popular destination for fly fishing, particularly for landlocked salmon and brook trout.

The river flows through a remote, heavily forested area, making it a relatively undisturbed ecosystem. Its rapid currents and numerous pools and riffles create ideal habitat for a variety of aquatic species. Several historic logging dams remain along the river's course, remnants of the region's past as a significant timber producing area. The Rapid River is considered one of the premier fly fishing streams in New England and is a popular destination for anglers seeking a wilderness fishing experience. It is also a notable example of a river that benefits from strict conservation efforts aimed at preserving its pristine water quality and natural habitat.
