3. Round Valley Reservoir
Formed in 1960, this is the largest reservoir in the state of New Jersey. The reservoir offers some excellent fishing including bass, pickerel, catfish, eel, perch, and two types of trout. It is also claimed to be the most southern body of water where lake trout naturally reproduce.
The reservoir is known for its crystal clear blue water. Camping, swimming, a scuba diving facility, a boat ramp and plenty of hiking and biking trail can all be found in this reservoir. Interestingly, it is occasionally called the bermuda Triangle of New Jersey as 26 people have drowned there since 1971, of which six have never been found.
