The 2026 Digest lists no special regulation for this stream, so the statewide trout rules apply: season dates, daily limits and minimum sizes.

Check before you fish. Access, stocking and rules come from New Jersey's own data and can be out of date. Posted signs and landowners' wishes come first, and private land needs permission. You need a valid fishing license.
