Have you considered putting a microphone (or hydrophone) into the
water.  It could work similar to a glass break sensor, sending a
signal when unusually loud and harsh noses are in the water, such as
someone falling in or swimming.  The only trouble would be to find a
sensor to work with the hydrophone.

Perhaps a simple glassbreak could be modified to be a "waterbreak".
The important thing would be to test it to see if its over sensitive
or under sensitive.
