However, it has been estimated that in 1924 and 1925 alone over 2,000,000 cubic yards of material were removed. These figures indicate that the rate has been less since 1906 than it was during the preceding 60 plus years. Power was first delivered from the constructed station, Edward Dean Adams Station, in 1895. At this point, the river is shallow and about 7,000 feet in width; however, the steep slope and rapid current in the area make the term "pool" a misnomer.

Also, it was noted that the rate of recession varies with the volume of water flowing over the Falls; that is, the greater the volume, more the recession. However, the weir caused a small decrease in the flow over the Horseshore Falls, thus making the conditions at the flanks of the Horseshoe somewhat less satisfactory. This increase in diversion highlighted the need for such a weir. In 1954, units of the Sir Adam Beck No. As the river leaves the gorge, at Queenston, Ontario, it widens out.
