OK WATERGIRL HAVE YOU TRIED IT? if so how many bads did it take?

that is right down the road from where i was born in Toledo Ohio.
yuk Ohio. Really what i am trying to find out is there any substance i can use without draining the pond that has good results?

I do not see any water behind my dam which is 2/3 of the circumference of an approx 80 foot diameter pond but is very deep and has steep banks.

it leaks an 1 inch or a little more a day and this Texas dought has not helped and i think it is contributing to the quickness of the leak. I believe this is a seep due to the steepens of the banks or slope on the sides of the pond - do not break the 3 by 1 pond rule is the thing to watch out for.
