This illustration shows how the bottom rock is inset and the water level comes up halfway on that rock. We did it like this except we ran the pond liner up higher behind the second rock so that the level of the water comes up to nearly the same height as the surrounding dirt. In fact on the patio side of the pond we put the liner across a shelf and up high behind the rocks which border the patio. This is now filled with dirt contained with plastic ground cloth so that we can plant bog loving water plants there. The papyrus and the sealing wax palms are two of the bog-loving plants.
I hope everyone isn't completely bored with these updates of our pond project. I took a picture of Laurie right after she finished hiding the liner edge with rocks.
Now the only thing left to do is for me to fix the leak in the bio-filter tank and fill it with stones so we can turn our waterfall on and start the filtration process. I'm also getting a little excited about planting water lilies and lotus flowers. They are really pretty flowers. They open every morning and close at night. I'm not really a gardener. Laurie does all the planting. I usually just build the infra-structure and maybe plant an occasional useful plant like a fruit tree or a papaya. But these water lilies are really fun to watch bloom. You also don't have to do any weeding. Having a lot of lilies and lotus flowers will limit the type of fish that we can put in the pond though. Koi will eat the lilies and root around in your underwater pots damaging them. I think we may just stick with some of the amazing varieties of gold fish. Large orange gold fish and black moor gold fish swimming around will be beautiful and the just eat dog food like our other small fish that we put in to make sure there would be no mosquito larvae.
