Green Pond is the name of both a lake and of a private lakeside residential unincorporated community within Rockaway Township in Morris County, New Jersey, United States. 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 fairly large (approximately 2.5 mi long and 0.5 mi mile in breadth at its widest point - 465 acres (0.72 sq mi) total), and the water clarity is high due to the lake's source (underground cold-water springs).
