I live just over a mile from that pond near State St. & 70th. It belongs to the property owners of the little rural subdivsion next to it. We were home shopping about ten years ago and what I learned from the realtor was that rather than the homes having individual septic systems, they all fed into one system with a large drain field. Guess where the drain field drains too. :shock: I'm not saying the pond has raw sewage, but I don't think I would want to swim in it or eat any fish out of it. But not to poop on the potential, it could be decent C&R spot if you can get permission. Be sure to wash your hands.
I found the Aumsville ponds on accident this last September when I followed some signs to a yard sale. The main pond is called Young Lake and is the most northerly one. It is public (owned by Marion County), has good parking, and even a restroom. Like a lot of small ponds, it is pretty weedy near the edges late in the year. Easy access close to the parking area, but just a handfull of places around other parts of the lake where it looked like bank fishermen (er, persons), beat the brush to get to. We took our canoe out and caught some small bluegill and perch. I saw a bass in weeds that was probably around 12 inches. I plan to hit it again this coming spring and maybe catch some bass. I hope there are some crappie in it, but don't know.
