Title: Map of the Waterways
Date: June 1878
Source: Colonel F.U. Farquhar
Description: Engineer Farquhar prepared this map of the Falls and its waterways in June 1878, after the falls had been reconstructed to be preserved.
- If the lightest color of blue represents the highest water level, how many times does the water level drop by the time it flows past the falls?
- What might be the purpose of the first drop the water level takes by the upper dams?
- What do you think the dark rectangles along the covered canal are supposed to represent on the map?
- If the lightest blue shows the highest water and the darkest shows the lowest, how might the high water in the covered canal (at the bottom) reach the lower water?
