Town officials say they’re receiving an unprecedented number of reports regarding turtles out and about in recent weeks—a phenomenon that experts attribute to an unusually high water table. Officer Allyson Halm, head of the New Canaan Police Department’s Animal Control section, said in 15 years she’s never seen such high activity. Though Animal Control keeps no formal count of snapping and painted turtle sightings, Halm said they’ve come in recently from areas including Long Lots Road, Carter Street, Greenley Road and Chichester Road. A concerned resident on Huckleberry Hill Road on Wednesday stood out to protect a turtle as it crossed Valley Road, she said. Dara Reid of Wildlife In Crisis, a 30-year-old nonprofit organization that serves Fairfield County, said she’s seeing about double the number of snapping turtles hit by cars than usual, including one that’s about 50 years old.
