I bought a 22 acre piece of property in a forest, overlooking two mountain ranges. Over time, I put up my house. The forest birds are amazing looking, so I got into birding. Birds are attracted by running water, so I thought of putting in a water feature for them.
Also, the mountain west is extremely dry, especially after five years of less-than-average rain and snowpack. So, people in the woods are extremely concerned by the possibility of fire. I thought if I had a pond, I would have a source of water already pumped up out of the ground (since electricity usually fails in a fire) that could be used to defend the property. Some people do this with a giant ugly tank on their property--I thought I'd be more aesthetic about it.
Once my 7000 gallon water feature was in place, the birds came. (Including a herd of about 50 wild turkeys which I have subsequently learned were placed in these woods by none other than our own Dan Blatt!)
I got excited about the idea of putting some fish in the water to make it "active." People recommended koi, which seemed prettier than goldfish. I was not sure where to buy koi, so I got on the internet, and for grins, typed in
www.koi.com, which landed me at Pan Intercorp, which just happens to be in my neighborhood. There endeth my sanity.
Now, I am working on a pond which is going inside my 15 x 32 foot greenhouse (so I can control the temperature and the predators...) I am grateful to have Koi-Bito magazine (bought all of the back issues) and the experts on these boards to help me do this right. Brian--I got serious inspiration for the design from the Momotaro DVD about putting parts of the filtration under the floor. This helps me actually have some, er, plants in the greenhouse too, which was the plan for that before it got hijacked by my koi-kichiness.
