The hole is in the bottom of the liner-- it's a one inch long slit.

What I would do...
1. Find a temporary solution. Put a piece of liner down over the hole,
with a heavy rock or plant on it. This won't stop the flow, but it may
slow it enough.
2. Find a temp solution for housing the fish, hospital tank, etc. Be
sure to provide proper filtration, oxygenation, screen over top to
prevent jumping, etc.
3. When pond person comes to patch pond, move fish to hospital tank.
4. After patch is in place, do some a partial water changes 30-50%.
5. Toss a few fish in at a time. The ones you like the least go in
first.
