First Welland Canal reason for the error is not known. On July 4, 1818, Merritt organized a meeting in St. Catharines. The outcome was a petition sent to Upper Canada Legislature to provide for construction of a canal between the Twelve Mile Creek and Welland River. Unlike Merritt's original water-canal plan, the petition included plans for allowing boats to cross the Niagara Escarpment. In 1823, Hiram Tibbetts, an engineer, was employed to make a formal survey for the route. He suggested to dig a channel below the surface level of Welland River between present-day Port Robinson and Allanburg, and then follow the Twelve
First Welland Canal Wainfleet, and had made significant progress before Deep Cut work was resumed the following April. However, the rains continued. On November 9, 1828, just two weeks' worth of work before completion of the Deep Cut, the banks of the cut near Port Robinson collapsed into the excavated channel, killing an unknown number of workers below. More landslides followed, and it soon became evident that making a cut deep enough as to use the Welland River as the source of canal water would not be possible. An alternate, sufficiently high source of water was necessary. Since the construction of a channel
