Also consider the minerals you are going to add to your pond from the well water. It might change your chemistry more than you might like or it could be a big help.
I have a spring adding water to our pond system and it is a God send. Even during the hottest and driest parts of the summer I notice a great help. Even though it does not keep up with evaporation, it helps a lot. My ponds do not go down like my neighbor's ponds.
