I have all sun yard front and back. I am putting in a waterfall rock wall and want to know if I need to have a drain in the bottom? The ponds and falls I have seen don't need them!The last question is will filtering be enough to keep the water clean? Thank-you for your time.

If you live in an area which will freeze over the pond, you should go with the drain. If you plan on using thick poly to hold the water, you may not need the drain. Your all Sun yard will produce a considerable amount of algae. There are chemicals to reduce the algal growth but most will do harm to any finny friends.
