Big Lake officials are urging residents to move their possessions to higher ground and to think about evacuating.  The board of trustees says rising water on the Missouri River could force residents out of their homes for a long period of time.  Residents are urged to take essential items and all their pets, to secure their homes, and to check on neighbors who may need assistance.  Evacuees who need a place to stay can contact Paul Grant at the Red Cross shelter located in the First Christian Church in Mound City.  That phone number is 660.442.3104.  If you have room to house evacuees you can call the Village offices at 660.442.3566.
