Bob :

If you can id where the front side leaks are you could do a front side patch with good clay and some bentonite added in to the clay. This could be done with the pond lowered but not drained all the way. If so you may be able to save the fish. But it depends on iding the location of the leak. Since we high jacked the thread the least I could do is find a few similar threads below.
