Green Pond is the name of both a lake and of a private lakeside residential community in northern New Jersey. The lakeside community is managed by two corporations, Green Pond Corporation and Lake End Corporation. Despite a name suggestive of a small lily pad and algae-coated pool, Green Pond lake is moderately large (approximately 2 miles (3.2 km) long and ½ mile in breadth at its widest point - 465 acres (1.88 km2) total), and the water clarity is high due to the lake's source (underground cold-water springs).
