I have a net OVER the pond now for the winter in Portland, Oregon (Zone 8)
and I keep the system running all winter and even tho the max depth is 30
inches I have no problems with freezing. I did get a 1 inch crust of ice
but the pump was circulating and the waterfall was falling and now things
have thawed and all is well. My wife worries about the stupid kids and so
do I. Our county codes say that ponds or pools 36 inches deep would qualify
for fencing and I have a million dollar liability rider on my homeowners
insurance (for the idiots and stupids and lawyers, or is that an oxymoron?)
What about the netting underwater rather than the metal grid. I can see
that there could be a problem with the solid metal grid.

I'm going to cross post this to rec.pond where you will get
more answers I think. I would think rebar would rust right
away.... "

it would take a couple years, but a kid can drown in less than
an inch of water... how deep is the pond, what dimensions &
how stupid are the kids? my grandparents had a lilypond about
6'x3' & we sailed boats in it & tried to jump across it all
the time (well, jumping across happened mostly when we were
all dressed up fancy for church or something...and we never
quite made the jump. got yelled at alot g). it couldn't have
been deeper than 3', i guess since we could climb right out. i
know they worried about us falling in & drowning, but we never
did. my grandpa ended up filling the pond in after we grew up
because the neighbor kids were apparently dumber than we were,
or maybe thier mom had less of a sense of humor about wet
muddy kids...
