Well, now I received a response from an email I sent to http://www.pondusa.com and they said that the OASE does function as a bottom drain - it just rests on the bottom of the pond and does not require a liner.

Now I am between the OASE BIOsys 5 Pond Filtration System: http://www.pondusa.com/filter5a.htm (the link has a neat little picture of how it works, it even has a satellite) versus the Aqua Ultraviolet ULTIMA II 6000: http://www.pondusa.com/filter6j.htm, which is a pressurized filter. If I purchased teh AU system, I could have a "true" bottom drain or just set the pump up so that water is pumped from the bottom.

When I was in San Diego earlier this week for a conference, I went to the zoo for a "luxury" and took a few pictures of their koi water feature. The poor koi were huge and only had about 24" max for their water. They didn't look too great. The pond feature itself was nicely laid out though, I loved their pagodas.
