Do some internet searching for something to put in the pond to slow the
leaks down. Maybe there is a clay or something that will suspend itself in
the water and clog the cracks up as it runs out the hole,

Water will always react with clay as any sculptor will verify, all clay
ponds, (referred to as bogs in our village) dry out in the summer.
What some people think are clay ponds, are actually gravel pits,as in most
quarries.
