If the entire area is clay then we really shouldn't have to "plaster" it, on the sides of anything, should we?


I believe they are talking about the top 2-3 feet that you said is sand. The water will rise up to that level and then soak/bleed out into the sand, never reaching the surface level of your topography. That might be ok if you also removed horrendous amount of dirt around the edges of the pond so it would have a nice walkable slope down to the waters edge. BUT why? Just take some of the clay that comes out of the bowl and pack down in the rim where there is sand and you will get the water to rise all the way up.
