Sunil, I made two trips last night, on the first trip I filled a 5 gallon bucket 1/2 full, within 5 minutes I had it filled to within 3" of the top with BG and water. They were gasping for air even before I got out of the ditch, I went much lighter on the second load which I took picures of. So between the two trips I have already salvaged 3 gallons of 2" BG without any water. My best guess is that that my salvage test put back 700-800 BG back into the pond and thats only a very small fraction of whats still in the 120 yard long drainage ditch.
