Pretty easy to isolate a water fall thats leaking.........but as Dan
stated, don;t leave it off longer than necessary........You can use a
heavy creame like half and half in a turkey baster and go along the
edges of the pond and watch for current flow, which will be pulling
the cream towards the leak.........I know of some folks that have used
food coloring as well for this purpose.....They make a fish safe dye
block, but its still going to mean shutting down all aerationa and
water movement so youy can watch for current flow pulling the dye.

I would recheck that waterfall and possibly temporary route any lines
so the water fall is out of the picture, and if the pond doe snot leak
its got to be the waterfall.......Waterfalls are perhaps the biggest
problem when it comes to leaks..
