Is it possible to create a water garden by means of a deep basin pond that would force the water back up hill to a small pond at the top and cascade the water down falls back to the larger basin pond? If so how could I possibly do this?
No Pump Water Garden
ummmm, gravety might just keep the water from wanting to flow up hill.
If electricity is the issue, you can use solar pumps (there are a lot on Ebay).
No, water will seek to level itself. So if you were to attempt some sort of underground tap into a deep basin pond from a lower pond what you end up with is 2 small ponds because the deep one would basically drain into the other until they were the same level.
