Update.... I gained an inch! Yeah.... Actually gaining is better than loosing I guess in the middle of a drought.

I did have two different locations where it was damp while filling on the bottom. Wasn't really wet, just damp enough to to have a little darker shade. Is there a better way to evenly spread bentonite? I have a large area so do you whip it with a shovel, try a broadcast spreader, sprinkle out of a cup? What is the best way for good even coverage?

Like I said though, oddly enough I jumped an inch out of no where with a tenth of an inch of rain last week so that was great. Just need a lot more rain. Almost all the ponds around here are very low.
