Atlantic County Lake Quality
New Jersey, 5 lakes, average grade B (Good)
Atlantic County has 5 graded lakes — a thin enough sample that one or two stressed lakes can move the county average noticeably. Use the per-lake pages below for what actually matters. With an average grade of B, Atlantic County sits comfortably above the New Jersey median.
Most of the county's monitored lakes are shallow — under 50 feet — which means wind keeps the water column mixed all summer and sediment-bound phosphorus releases back into the surface layer whenever the bottom is disturbed. Lake Lenape (A) is the cleanest in the county.
