Backyard Getaway, I didn't know that lava rock decomposes. Thanks for that tip. Will have to do away w/the lava rock another way. We are very handy and so will attempt to do this ourselves. Yes it is the waterfall that leaks in the back, but I like that part of it, though it wasn't really done well to begin with. So maybe we will knock it down and create a different type of water feature. I have accumulated several pottery style lamps (minus the electrical parts)in various heights and shapes. I have painted them and was going to use them as a varied level water feature. I was going to put them in front of the raised garden in the front yard and eliminate that plastic pond liner there, but maybe I'll just put them on top of the river rock fill in and make it a focal point.....hmmm, you have me thinking now. Thanks for all your helpful comments.
