I just called my local Mosquito Control folks: they said that they use the
bacillus thurensis directly in water, but spray malathion from the trucks at
night that cruise the streets. She said the amount they use won't hurt the
fish, and I understand that *certain* amounts of malathion can be used in
the pond for various critter control. I also ususally keep several pounds of
activated charcoal in my waterfall setup as a "just in case" first line of
defense against toxins. In your opinion, is this sufficient?

You need to check with your locals about what they are spraying with.
Many localities are spraying with Bacillus thurensis, which is harmless to
plants and animals, save of course mosquito larvae.
Happy ponding,
Greg

With the hysteria over West Nile virus, localities are spraying to kill
mosquitos. How does this spraying affect ponds, if at all?
