The Day County Sheriff's Office posted about the incidents and said a deputy was able to get the man to safety. GFP officials are reminding those on the lake to be mindful of the ever-changing ice conditions and do not travel on the ice at night or in poor visibility if you are not familiar with the lake you are on.
