Newtown Underwater Search & Rescue recently conducted boat maneuvers on Lake Lillinonah.  While outdoor temperatures over the weekend reached into the 70s, the water was still only 50 degrees. While the first responders were out, they saw many kayakers and canoeists, very few wearing life jackets.  While NUSAR officials say they are prepared to respond to recovery calls, they prefer to meet boaters in a different way.
