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 of the Welland Canal. In 1818, William Hamilton Merritt borrowed an instrument called a water level from Samuel Beckett, a mill owner in St. Johns. Along with George Keefer, John DeCew, and a couple of other neighbours he set out to survey a potential route for a water canal. From the headwaters of the Twelve Mile Creek near present-day Allanburg, they planned a line three kilometers south to meet with the Welland River. A ridge was encountered along the way, and using the instrument, the surveyors calculated it to be 10 meters high. It was actually double that height; the
