Gmax,

Just remember mixing the water column in a trout pond can be a Catch-22. That is, you could warm up the water column and make it too warm for the trout. On the other hand they won't make it in the cold water if the oxygen gets depleted.

Hopefully your pond is far enough north and/or doesn't have any of these issues to concern you.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
