Big Flat Brook is a picturesque trout stream located in the northwest corner of New Jersey, flowing south approximately 28 miles before joining the Delaware River. Considered one of New Jersey's finest trout waters, this beautiful stream features varied water types from fast pocket water in its upper sections to slower pools and runs in its lower reaches. Its clear waters flow over a bottom primarily consisting of larger rocks and shale, providing ideal habitat for various trout species and supporting diverse aquatic insect populations. The stream's setting amid the natural beauty of Stokes State Forest and the Delaware Water Gap National Recreation Area makes fishing Big Flat Brook not just about the catch but also about enjoying the serene natural environment of northwestern New Jersey.
