Littlestfish, you have waxed eloquent regarding a very common problem which tears at men's hearts. Very detailed, vivid explanation. I plan on doing similar on a larger scale. I have bought a 10" X 10" tamper and intend on using it on one side of my pond which is sandy. I will put down bentonite and ruin myself tamping. You have given me great ideas on how to discover sources of leaks.
What brand of baseball bat do you use, eh; also the weight and length. \:\)
