I'm not sure what to make of it but the leakage on the dam has been reduced quite a bit. After applying DB 100 last summer the leak slowed but then seemed to increase almost the same amount as previously thru the fall.
I,ve been watching it since the snow melted off and as the ground dries the leak is much reduced from last year, it hasn't stopped but I am impressed.
Why can't things be simple! ;\)
