Decatur Waterworks: then and now

DeKalb County Parks has an aerial photograph of the old Decatur waterworks on its website, and who could resist comparing it to how the area looks today?

Using the railroad tracks for orientation, it is then easy to match some of the ruins. On the archive photo, note the now-gone dam and lot of water under the elevated part of the railroad track. The dip in the land is still perceivable except now it is densely forested. Click to enlarge.

For some photos of the area, at ground level, see this older post as well as photos posted by CHCA [ PATH construction | Waterworks ]. Additional information is available in the County's Mason Mill Park page.

In Peachtree Creek: A Natural and Unnatural History of Atlanta's Watershed, David R. Kaufman reserves a chapter for the South Fork of Peachtree Creek, and gives us some history of the waterworks and the Medlock area. Courtesy of Google Books, you can read this chapter online.
