Koi Ponds...

Just wondering if anyone else has a koi pond? I used to install them a few years ago and had one at my old place, now we are putting in the first half of a 2 stage pond. Gona make it about 13'longx5' wide for half of it, and 7' wide for the other half(kidney shape). average about 4'deep. We have a 2 level front yard and this pond will be on the upper level and will eventually flow into a much larger pond below that might or might not get built this year. If anyone has a pond could they share pics? Ill post pics when Im done, wont be for a few weeks for sure!
