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

The Feeder connected directly to Lake Erie, but it was long, and, not intended as a ship canal, of insufficient capacity. Over the course of the canal's first full navigation season in 1830, it became evident that a more direct route was necessary. In March 1831, a location called Gravelly Bay (now Port Colborne) was chosen as the new Lake Erie terminus for the canal. It was one of the closest
