About Black River (Lamington River)

Known as the Black River in its upper reaches through Morris County's Hacklebarney State Park and as the Lamington River downstream, this freestone stream is one of NJ's most scenic and underrated trout fisheries. The gorge section through Hacklebarney is tight, rocky, and holds wild brown trout in its cold, shaded pools. Access through the state park is excellent and pressure is lighter than the South Branch.
