Obviously concrete ponds work since concrete swimming pools work. In
fact all of the native fish hatcheries around here use concrete ponds.
Our pond is a very old concrete swimming pool (over 50 years old) with
the deep end filled in with clay so that it is about 3' deep.

I wonder why you didn't leave it deep?


Because water lilies don't grow in deeper water very well. We have
about a dozen water lilies. Also, I can use wadders in cold weather
when I am sinking the pots for the winter or putting the pots back out
for the summer.
My largest and most prolific lilies grow in 48" of water.
