You know I forgot to mention about my koi pond. My first shovel full of dirt had bricks in it. My second shovel had old nails. After that I found old glass mason jars, electrical insulators, charcoal, and my favorite the hardware from an old door, 2 hinges and a door knob. It was about this time I starting cursing the previous owners, how lazy do you have to be to dump garbage in your yard and bury it? But the next shovel I drove into the ground hit a rock. It was big, I dug around it and it was a perfect tan flagstone block. Over the course of the month as I dug I found enough flagstone to landscape the entire pond. Everything you see in the picture I posted was free, and found inside the whole that is now filled with water. I tried to convince my wife that this was a sign from above that we were meant to be koi owners, she didn't really buy it, but she was glad we save a couple hundred dollars on rock. That's the best story I have so far about my project, well aside from hitting the house's old well, but that's a story for another day.
