In Niagara Falls and opposite the Greenhouse has been there since August 6, 1918. It is a mute reminder of near tragedy and a spectacular rescue. The steel barge, loaded with rock and with three men aboard, was being towed to the upper river by a Hydro tug when its tow line broke and it set adrift. Fortunately, the men thought to open the dumping hatches in the bottom of the craft and the scow was grounded 767 m from the brink of the falls. Frantic efforts were made to rescue the men all that night and until late the next day. Finally a breeches-buoy was rigged from a powerhouse on shore to the rig. After several attempts were made to throw a line across to the rig the line became tangled, preventing the buoy from reaching the barge. William "Red" Hill Sr., a famous Niagara River daredevil volunteered to swing himself out to the obstruction hand-over-hand above the raging water. The breeches-buoy finally reached the scow and the men aboard were rescued. index American Falls Height 184 ft (56 m) Width 1060 ft (320 m) Volume of flow 10% of total Horseshoe Falls Height 176 ft (54m) Width 2200 ft (675m) Volume of flow 90% of total Total Flow Over Falls April 1-Sept 15: 100,000 cu ft/sec (2830 cu m/sec) (8am-10pm) Sept. 16-Oct. 31: 100,000 cu ft/sec (2830 cu m/sec) (8am-8pm) All other times: 50,000 cu ft/sec (1415 cu m/sec) Total Average Flow of Niagara River (before diversion for electricity) 202,000 cu ft/sec (5720 cu m/sec)
