About this water

The Musconetcong — the 'Musky' to everyone who fishes it — is northern New Jersey's long, hardworking trout river, running down through Hunterdon and Warren counties with Year-Round Trout Conservation Area reaches at Point Mountain and around Stephens that hold stocked browns and a satisfying number of wild and holdover fish. It's a freestone with a limestone influence in places, fertile and decently hatchy, and the conservation-area water rewards anglers who fish it thoughtfully across the whole year. Like all New Jersey trout water it warms in summer, so the cooler months and the cold-water reaches are where the better fish ride it out. Mind the thermometer and fish the special-reg water with the care it's set aside for.
