Perhaps I didn't word that correctly. Cats are more water averse and can swim that distance if they decide it is really necessary. Foxes are quite happy to swim and will do so on a regular basis. Even if there was some disincentive to foxes, once one reaches the island then it is likely to stay to cause greater havoc with the birds before overcoming its disincentive to leave. I suspect overall there would be no advantage.

But surely a 100m swim would reduce the number of visits, even if it
doesn't eliminate them.

If the major problem is people then constructing islands
might help.  If
it is foxes or cats then don't bother.  Both can swim at
least 1 to 2 km
if they decide it is necessary.  A few hundred metres (in an 18
hectare dam) is not even a barrier.   Plus if the water level goes
down then the
distance becomes even less.
