Yesterday, I decided to start from scratch with "Mount Rushmore", so I dug it out and now the waterfall mountain is a large upper pond which is the same width of the orginal pond, but half the length, it also be the same depth as the orginal. As seen in the picture it still needs 1 more row of block and the front of the upper pond still needs constructed. There will be some small fish in the upper pond, however if they seem to flow to the lower pond they will be removed. The inside will be lined with the old pond liner, and the outside of the upper pond will be covered with rocks and plants.
