Winnapaug Pond (also known as Brightman Pond[2]) is a breached saltwater lagoon in Westerly, Rhode Island, United States, connected to Block Island Sound by the Weekapaug Breachway, which was constructed during the mid-1950s.

[3][4] The 2.5-mile (4.0 km) lake is separated from the Atlantic by a large sandbar.

[7] Winnapaug is relatively small and shallow, and is favorable for kayaking.

[2] It is one of nine coastal lagoons, referred to as "salt ponds" by locals, in southern Rhode Island.
