The Lehigh River is a scenic 105.7-mile-long waterway flowing through eastern Pennsylvania, originating in the Pocono Plateau and emptying into the Delaware River at Easton. This navigable river carves its way through varied terrain including a 1,000-foot-deep gorge in the Lehigh Gorge State Park, creating diverse habitats for numerous fish species. The Lehigh is characterized by its clear, flowing waters that range from swift rapids to calm pools, making it a versatile fishing destination. The river's water quality has dramatically improved over recent decades thanks to conservation efforts addressing historical industrial pollution, transforming it into one of Pennsylvania's most underrated fisheries. The river offers opportunities for trout, smallmouth bass, and other species throughout its course, with fishing conditions varying significantly by season and section.
