Fig. 1. Falls of Niagara, Canadian Branch, 1890. (By permission of Baker Art Gallery, Colombus, Ohio.) Sheet of water to the right of line bb (west side) has since been curtailed 415 feet, on account of power diversion. The falls to the left of line aa are being drained by the diversion, which, when it reaches the franchise amount, will leave 800 feet of bare rock on the Goat Island or eastern side, thus throwing the remaining falls entirely into Canadian territory.
