 Although an Act was passed in May 1730, it was met by opposition by a number of millers on the river who would have seen changes in water powering their mills.These millers were given rights over the water usage, which would effectively allow them to shut the navigation for two months per year.This, coupled with the fact that the Act specified for the river to be made navigable (and not for the construction of a separate canal), meant that Hore's recommendations were never realised.
