Ok, so, I guess I'll start!
This is our pond, no telling how many gallons, but several anyway. It was dug out by dozer and backhoe, is unlined, and sinks to a depth of 14 feet at the center. It's fed by natural springs that have been channelled to drain into it from the top, and rainwater. This is almost about as full as it gets; earlier in the spring it was about 6 inches higher, but with the heat and summer coming on, the water level will drop considerably, going down several feet lower by the end of October before the rains start again.
The ugly aluminum protrusion in the middle is the intake pipe for the pump we installed, and from this end, you can just make out our Poseidon stature that guards the small upper pond at the top.
Next is the pump inside its "house." We wanted a really nice, loud waterfall from the upper pond to the main one, both for the sound and for oxygenation, so this thing puts out 1800 gallons per minute. Diameter of the aluminum input pipe is 12 inches; the output pipe measures 10 inches in diameter. At the very left of the pic is an electric oil-filled heater to keep water in the impeller housing from freezing in winter when the pump is off, and the pump house is insulated with 3/4 inch thick foam pads.
Here's the small upper pond at the very top. It serves mainly as a reservoir for the waterfall. Poseidon stands 6 ft tall, and we still haven't found a good pitchfork for him yet. Since we live right smack in the belly button of the bible belt, we couldn't find a Poseidon without a ridiculous fig leaf covering his privates, but that's the way it goes. I really need to do a ton of work here, getting rid of the vines and saplings and crap that have grown all through the rocks. Bruce and I cemented in I don't know how many tons of rock to create this thing, and I swear to God, I'll never do it again. Major pain and backache!
The whole point of all this labor and expense was to create this waterfall. It looks a ton better without all the greenery at the left, since the cascade extends quite a bit under that canopy of vines and stuff. In late fall, when the water level of the main pond is several feet lower, the falling water makes a wonderful roar when it hits the rocks we put in below it.
Finally, since this is, after all, Arkansas, though koi and swans would be nice, we don't have koi or swans. Instead, we's gottum catfish and geese! These catfish are monsters--some over two feet--since we feed 'em dry dog food spring, summer, and fall, and they'll eat out of your hand. I tried petting one a few weeks ago but the sucker bit the **** out of my finger; anyone who says catfish don't have teeth doesn't know catfish. These are mostly channel cats but there are some blues, and their teeth are like extremely sharp files.
So there you have it, our pond, a little wild, a little woolly, but we like it a lot, snapping turtles, water snakes, catfish, crayfish that dig silly little holes in the mud on the banks, all of it.
So what's your pond look like? How did you build it? What made you decide to go to the trouble?
We want to know!
