Connecticut's Department of Energy and Environmental Protection says the body was pulled Tuesday from Lake Lillinonah in Bridgewater after a homeowner spotted it from a dock.
The body was transferred to the chief medical examiner for identification.
Police have been searching for 33-year-old Eric Langlois of New Milford since he went missing a week ago. He had told his wife he was heading to the Housatonic (hoos-uh-TAH'-nihk) River to retrieve a lost bicycle.
Police say Langlois crashed a mountain bike on June 10 in the river, which was swollen from heavy rains. But he managed to swim to shore. He told his wife he was going back the next day to look for the bicycle.
