Just a thought here... What is the temp of your ground say about 6" or a
foot down? If it is lower than the pond temp you could run 100' or so of
3/4 or 1" pipe buried under your grass, even in a shady spot if you have it.
Then when you want to cool the water divert your flow through this piping.
Moisten the ground if it is very dry as water will dissipate heat faster
than air. Same idea as heating pool water by piping it up on the roof -
just opposite.

Does anyone know if there are any pond pumps that also refrigerate the
water
that passes through it? It's getting really hot here in the Sacramento
Valley.
The pond got to 80 today and could get hotter. Throwing the contents of
the ice
maker into the pond only lowers the temperature by one degree. Not really
much
help.
