Tell us more about this underwater camera. Who, what, where and most
importantly HOW? Random shots, x/hour, motion activated? And as autumn
is
descending on So. Cal which means that overnight temps are going to be
down
to the 50's, how can I still hear my pond in my bedroom overnight???


I doubt motion activated would be that great, most are infrared based,
some are ultrasound, but I suspect neither would work well in a pond.
Maybe you can find a microwave motion sensor.

iirc, microwaves (at least at the frequencies permitted for this sort of
application) work even less well in water.
