and here is the last one, it shows just how high the berm is for the falls. we did virtually no planting in the pond or around it (homeowners request). we put the falls in the downhill spot so that it is visible from 3 rooms on the house. from the house it was hard to tell that the berm really is so high, however from the side or back its really about 2-3' raised over grade.
