Aaron showed me the "environmental art installation" deep in the woods behind the honors house.
I still consider it a "pond", even if I have completed my requirements for a degree in Art.
I think its very cool, but I do see a few small issues-- not in aesthetics, but in the engineering.
Anyhow, to keep the pond from stagnating, a little aqua-culture wouldn't be a bad idea.
I'd hate to step on anyone's toes. But you know, a stagnant pond filled with rotting vegetation and mosquitoes isn't anyones idea of aesthetics.
A quick first step would be making a natural bio-filter. It sounds complicated, but its not. Having water trickle through a pile of pumice (volcanic rock/lava rock) works as an excellent biofiter. Its naturally very porous. The pond is fed by a drain pipe. We'd just have to place a pile of volcanic rock inside the bottom of the pipe. A cubic foot of volcanic rock would work, and its available at Lowes for $4.
Having plants and animals inside the pond will also keep it in a natural balance and prevent it from becoming a stagnant cesspool.
At first, I thought about goldfish. But my dad said native catfish would survive the winter better. Fortunately, there's a company in newtown, ohio:
http://www.jonesfish.com/content/estore.asp that sells catfish for ponds and for farming. Plus catfish are bottom-feeders and will eat anything and are very self sufficient. Mosquito fish are also an option, and they sell them too.
The fish need oxygen, so a couple of plants will help too. I see that jone's fish sell plants, so they'll know what grows in ponds here.
I know Taro growns well .... I see it everywhere in Lousiana-- very prolific. However, i found that it's only tolerant to zone 8, so thats not an option...
