Pond building has been discussed in the last 3 issues of Pond Boss Magazine. If you're not a subscriber you ought to buy the back issues. Probably learn a lot. I only see a couple of difficulties. First, you have to pack the dam dirt, layer by layer, while you're stacking it. I mean really pack it. Also, the 8n loader bucket won't carry much at a time. If you have a loader bucket on the hoe, it will work better. I think most people here are do-it-your-selfers when possible. Have fun.
