since your pond will be a lot bigger than this one. there will be much more pressure of water load. not sure if similar setup with no mortar will hold up.
also, from the pix, looks like solid blocks were used. it has more weights density so it hold up more than the hollow 16x8x8 cinder blocks. I assume you are using cinder blocks. anyhow, if I was you, I would use mortar to keep them together.

This is what I originally had in mind. Regenmeneer...what can I do so I dont have to worry about ground collapse? I also think I will use the 16X8X8 blocks instead of the 6" ones. I have found the larger size locally...so I will go with them.
