Thanks Wyomiles,
But those links just talk about the process of gleying as I had learned about it in school- the process of water-logged soils becoming oxygen depleted and thereby turning grey from the iron and such. The only way I can see this possibly helping seal a
pond is that clay particulate settle to a particular horizon in the soil profile. However, this clay is not compacted or anything - it's just there in larger quantities than when it's spread over the entire soil. I guess that's better than nothing, but you still get leakage and what gleying is supposed to do is prevent that.
So far I am becoming less convinced that gleying really has the affect of sealing the pond from
water loss. I think if I have to seal a pond, I'll go for compacted clay.
I appreciate your help.
