Cecil has one of many good questions I would ask befor " moving the fish and water" How Big is the first lake? How do you plan on moving the water? How do you plan on moving the fish? With the water flow or by seining and transferring by tanks? Yes you do have to move the entire pond (incliding the food chain) with the bass. Will you cause and extreme water turbidity by moving this water to the new pond? Be very careful of the weather forecast when planning this event. Heat, rainfall, cloudy calm conditions ... anything that may cause additional stress to your fish. Does he plan on redoing the first pond? Why not have two!!!
