Whoo Whee. This a classic "it depends". grin

It all depends on if the water is stratified, the ambient temp, pond temp, etc., etc.

For instance. If the pond did have a thermocline, and you pumped cool bottom water over an artificial stream and the ambient temp was greater than the water temp, it'd warm it up.
