    river in Maine

    Flowing from West Grand Lake to Big Lake, Grand Lake Stream is a unique and historic fishery.

The stream is also famous for its robust population of smallmouth bass, particularly in the warmer months, offering diverse fly fishing opportunities. Many sections are fly-fishing only.
