You will have a prevailing wind most of the time, probably from the southwest. I plant trees pines, spruces on this side so there are no leaves bowing into the water. On the other side I plant trees with leaves that will mostly blow away from the pond. However I love Weeping Willows and have planted one along with the pines and spruces. They have small leaves and have much less impact then large leaves would have blowing into the pond.
