The Millstone River in New Jersey offers anglers a rich and diverse fishing experience across its 38-mile length. Flowing through multiple counties including Somerset, Middlesex, and Mercer, this tributary of the Raritan River contains over fifty fish species and provides excellent fishing opportunities for both novice and experienced anglers. With its varied habitats ranging from shallow riffles to deep, slow-moving pools, the Millstone River has established itself as one of central New Jersey's most underrated fisheries. The river is further enhanced by dam removal projects that have reconnected historic migratory pathways, particularly benefiting anadromous fish species like American Shad.
