Lebanon, NJ (Round Valley) fishing report
Round Valley Reservoir is a deep, clear New Jersey impoundment known for cold-water gamefish — it holds lake trout and rainbow trout along with strong smallmouth and largemouth bass populations. Trout fishing is best in the colder months and early season when fish hold higher in the water column; as summer warms the surface, trout slide deep to the cool layer while bass turn on in the shallows and along the rocky structure. Fall brings another active feeding window before winter.
For trout, fish deep once the water stratifies — troll or jig the thermocline and follow the bait down as summer pushes fish into the cold layer. Smallmouth relate to rocky points, drop-offs, and humps; work tubes, drop-shots, and crankbaits along that structure. Largemouth hold in the shallower cover and warm-water edges. Water temperature is the master dial here: it sets how deep the trout suspend and when the bass move shallow to feed, so let the temperature guide your depth.
