From an atlas of Cambria County published by Caldwell in 1890. The atlas was about to go to press when the Flood occurred. All the

copies were hand-painted in watercolor to show the path of the Flood. The dam and lake are to the right of center at the top of the map. Johnstown is in the foreground. Blue areas are the main flood wave. Orange marks where the flood wave divided at Franklin St. Methodist

Church. Pink marks the backwash off Westmont Hill up the Stoneycreek to Kernville.

Topographical view of 1889 Floodpath

From an atlas of Cambria County published by Caldwell in 1889. The atlas was about to go to press when the Flood occurred. All

the copies were hand-painted in watercolor to show the areas that were destroyed in the Flood. The area of downtown Johnstown that was ruined is shown in blue. Most of the buildings shown as black rectangles were crushed by floodwaters.

The Flood came down the Little Conemaugh River, which enters the map from above. The Stone Bridge is just off the left edge of the map. This map makes it easy to see how the Stone Bridge’s dam of debris created a filthy lake covering most of Johnstown.
