Thames Navigation Commission

The Oxford-Burcot Commission was reasonably successful. Thus, the permanent Thames Navigation Commissioners were appointed through a further act under King George II in 1751, the (24 Geo. 2. c. 8). This commission had similar powers covering the whole of the river down to Staines as far as a point marked by the London Stone; below this point the rights and responsibilities for managing the Thames were vested in the City of London Corporation. Earlier commissions had been created by acts as early as 1695, although these had limited terms.

The Thames Conservancy was established in 1857 to take over duties from the City of London because of falling revenue from boat traffic. Not long after, in 1866, it was considered best to have the navigation of the whole river under a single management, so the Thames Navigation Commission was subsumed by the Thames Conservancy.
