I have a small pond 6ft by 4ft which is 3ft deep can anyone recommend from
personal experience a good small yellow water lily that won't take over the
whole pond.

It also depends on how much sun the pond gets. The water lily will only
open its flowers in sunshine, and a vigorous variety will not grow so
vigorously in a pond which is shaded part of the day.
