Theo, it's a little tough to tell just by eyeballing it, but I'm guessing it will be about 12-15 feet at the dam and around 100-125 feet in diameter. It's going to be very long and very narrow. I'm guessing the average diameter across the upper half of the pond would be around 50 or 60 feet. It should be fun to fish from a tube or bass buggy. The banks are steep and heavily wooded, so it might be tough to fish artificials from the shore. But that's why I have the other pond. I like both types, although they are very different. I'm thinking I will have a harder time keeping rough fish out of this second pond as the creek probably has it's origin somewhere in the Wichita Mountains 20 miles away. Once the pond is mature, I would hope that the bass could stay ahead of any small rough fish arrivals. Is there any sort of screen or fence that is effective in keeping larger fish from washing in? I would think that limbs and bark would quickly occlude nearly anything you installed to block the entry of larger rough fish after a big rain.
