ymurf, I no longer have any standing water at the toe of my dam but the ground is still a little damp. Went from about .5 inches loss a day to a little over .25 inches per day. Still waiting on the rain to bring the water level back up to see if it holds. I plan on ordering another 6 gallons even though I'm not absolutely sure it fixed the leak......because it does a pretty good job of clearing the water and does not cost that much more than the equivalent amount of alum.

Seems like belkins456 had good results.

I would be interested to find out if anyone else has tried DB-100 and what their results are also.
