This appears to be a 12" Flannelmouth sucker. It had not been here all that long.
There was no contiguous running water to this point.
This was at least 10 miles via ECC to get to the Blue Ridge Reservoir.
There were no obvious signs that it'd been carried here by a bird or mammal.
It must have swam up here during the last high water event and caught in a now dry pool.
