Step 17: Hide the stream trough and fill up the pond
To make the stream look a lot more natural I added some more of the plentiful rocks on top of it.
Covering it up also helps to reduce the amount of evaporation from the flowing water.
I placed a few of the rocks on the bottom of the trough as well as over the top, to cause some sections to over flow down the back wall. You can see the effect in the photo.
Once the rocks are all in position, fill up the pond from whatever supply you feel is appropriate. I filled my from the tap as it was before I had my water towers.
