Before the dam closed, surveyors mapped the valley: every creek bend, road, pond dam and farmstead. Everything on that sheet is still down there — and a roadbed or a pond dam from 1940 is structure today.
Pre-Lake Topo lays those sheets over your lake so you can follow the old creek channels and roads under the water you fish.
