Once you get a possible height, make a wall that high out of some foam
insullation board and look at it for a few days to see how it feels. You
might want to paint it a color approximating the brick rather than leaving
it white or blue.

We are building a 20'x20' formal koi pond (concrete block and liner
inside, brick outside above ground), 6' deep with a 6' radius
semi-circle upper pond/falls. The brick will be capped with a 2"
Bluestone or Limestone coping.

We can't decide how far above the ground to extend the main pond.
Most importantly, we want it to be structurally sound (water/ice
pressure in Upstate NY). Also, we want it too look nice (i.e, not too
much brick showing so as to be overwhelming across the 20' expanse).
Finally, we want it to be functional for sitting next to and in order
for adults and children to view the plants, feed the koi, etc. We
will make the upper pond 1' higher than the lower one.

I am not speaking from actual experience...just gut reaction...I'd stack
some bricks on the ground and sit on them...Look for a comfortable height
that your little ones can climb up on, but high enough that an adult can
sit
fairly comfortable. My gut say 18-22 inches.
