Lake Cochituate is an open body of water in Natick, Wayland, and Framingham, Massachusetts. Originally a reservoir serving Boston, it no longer serves that function, and is now a local recreational resource and home to Cochituate State Park and site of the Wayland One Mile Swim and 3 Mile Challenge held annually in June.
Lake Cochituate consists of three linked ponds known as North Pond, Middle Pond, and South Pond. A large peninsula in South Pond is the site of the US Army Soldier Systems Center, and the eastern shore holds the trails of Pegan Cove Park. Middle Pond is home to Cochituate State Park, which includes boat ramps and a picnic area. North Pond is the site of both Wayland Town Beach and Saxonville Beach of Framingham.
