Unless the soil is like pottery clay, the bank probably will not stay 3' deep right off the edge for long. Lining the pond 2 or 3 wide then 1 or 2 wide on top of that to make a "step" to get out of the pond in case anybody goes in might be a good idea, plus it might hold the banks in place for a longer period of time.
