Dam. What Could Have Been.
What remains here appears to be the remnants of the Ballville Dam. The river left side seems to have portions that act like a small low-head dam—though it’s unclear whether this is part of the original structure or a natural ledge the dam was built on. The river right side has a much gentler gradient. I haven’t investigated it much, so more exploration is needed.
That said, there are surf opportunities at the right levels if you’re willing to experiment. Just keep an eye out for changes in flow and always scout before you drop in.
