Without exception, national wildlife refuges follow state and federal fishing regulations, including license requirements. Refuge fishing programs change frequently. Before fishing at a refuge, always check with the refuge staff regarding species, season dates, other regulations, special conditions and maps of fishing area. Be aware that most refuge offices and visitor centers are closed on federal holidays. In addition, refuge-specific sport fishing regulations appear in 50 CFR 32.20 through 32.72.
