 You know, this dam, like all dams, is a barrier to aquatic connectivity, so fish, mussels, you know, hellbenders, they can't make it through this dam. Hill joins Dalton on the bank, and the pair submerges. It's not long before they find a hellbender under a large rock, about four feet underwater. It's just far enough down. You can see the entrances on that side. Looks like a small adult.
