Lake Pocotopaug is an unincorporated village and census-designated place (CDP) in the town of East Hampton in Middlesex County, Connecticut, United States.

[6] According to local legend, some time long before the area was settled by whites, the tribe living there felt they were being cursed by their irritable Great Spirit.

To try to appease him, the main chief agreed to sacrifice his daughter, who willingly threw herself into the lake and drowned.

The Wangunk were also said to have hunted on Spellman's Point, now a quaint street lined with cottages, using loud noises to scare the animals to the end of the peninsula, and thereby an effective way to gather food.

[citation needed] Sears Park is located at the lake and has various swimming, boating and recreational facilities for residents.

In recent years the lake has become a place of ecological study due to the large-scale algae blooms that started appearing in 2000.

[citation needed] The lake has scattered rock hazards, including one marked by a small memorial lighthouse in its southeast portion.

Lake Pocotopaug is in northeastern Middlesex County, in the northern part of the town of East Hampton.

It is bordered to the south by the village of East Hampton and to the west by Meshomasic State Forest.
