1904 Map of Dayton

The infrastructure of the Great Miami River basin is prominently featured, including the Taylorsville Dam and Huffman Dam, crucial for flood control. To the east, the village of Osborn and nearby Fairfield sit at the confluence of the Mad River and Mud Run, illustrating the region's complex water network before later urban expansions. Large thoroughfares like the National Road and Dayton and Troy Turnpike intersect small communities such as Ginghamsburg and Phoneton, reflecting the era's transition from water and rail to early automotive routes.
