If you have a dam I would strongly suggest against planting any trees along its edge, as the roots will cause holes and your pond will leak or worst. If on the other hand you're not planting by the dam, at 10-15' from the ponds edge the roots will enter into the sides of your pond causing possible leakage as well, not to say anything about sucking the pond dry during times of drought "causing lower water levels" pine needles are also VERY MESSY.
Gene13, a perfect summary of what I have experienced also...except to add that pine trees may well be the worst in terms of structural damage done.
