1933 Map of Lacon

About this map

The Illinois River corridor dominates this 1933 survey, defining a landscape of expansive backwater lakes and riverfront settlements in Marshall Co and Putnam counties. The eastern bank is anchored by Lacon, where the Alton railroad terminates near the river, while across the water at Sparland, the Chicago Rock Island and Pacific tracks follow the western shore. This era represents a complex aquatic ecosystem of sloughs and basins like Senachwine Lake, Sawmill Lake, and Goose Lake, which provided both natural resources and navigation challenges before modern channelization.
