I think it may make a mess initially but gravity always has it's way with objects. In a week or so it would find it's way down to the bottom and hopefully plug up some leaks?? Farmer rick i'm like you...we have had soo much rain that it's difficult to monitor. I do notice a quick loss though once it gets above the current level. I'll keep fingers crossed and see what happens over the winter! I've heard of putting saw dust in transmissions to keep them from slipping! If it will fix a transmission surely It will fix a leaky pond? ha
