@gpserror A creek like vein of surface water is visible on the West side of I-77 and a broader water area from I-77 to  from the OSIP III 6 inch layer. I'll visit the Kroger Wetlands and try to survey from the Drayer Spur Trail to see if I can view a culvert to connect the water on both sides of I-77 to Duck Creek on the East side. I haven't spent that much time in the Kroger Wetlands (though I live in Marietta if you need on the ground surveying elsewhere). I've added the visible water in https://www.openstreetmap.org/changeset/135344475
