Control of Pollution Act 1974

48 Power of water authorities to exclude unregistered vessels from rivers etc.

(1) Where it appears to a water authority to be appropriate to do so for the purpose of preventing the pollution of streams in its area, the authority may make byelaws providing that vessels shall not be on any such streams which are specified in the byelaws unless the vessels are registered by the authority in accordance with the byelaws or are exempted by the byelaws from registration; and a person who causes or knowingly permits a vessel to be on a stream in contravention of byelaws made by virtue of this subsection shall be guilty of an offence and liable on summary conviction to a fine not exceeding £50.

(2) Byelaws made by a water authority in pursuance of the preceding subsection may authorise the authority to make reasonable charges in respect of the registration of vessels in pursuance of the byelaws; and no charges shall be payable, by persons in or from vessels registered by the authority in pursuance of the byelaws, in respect of the use by those persons of facilities provided in pursuance of the preceding section by or by arrangement with the authority.
