Meadowlark,
I'm pretty confident... This is the guy that the County Extension Office guy recommended and had do his pond. He say's he's done hundreds and never had a "dry hole". He did a "test hole" to see how it looked and said it would be fine. Looks like my middle is going to be about 8-10' deep.
Yes, bahia grows VERY well around here. Will probably germinate immediately. We've got at least a month before the first frost. I'm hoping the goats will help keep it down. The only shade is the willow that I had moved close to a corner of the pond, oh, maybe 5 or so feet from the edge. I gave each tree 30 gallons of water yesterday and will again today hoping to keep them alive.
Thanks for the responses...
