Control of the Cut passed to the British Transport Commission with the nationalisation of the railways. The cut was damaged by the floods of 1953, which affected much of the East Coast, and the Transport Commission attempted to close it in 1954. Local opposition was strong, particularly from the yachting community, and control of it passed to the East Suffolk and Norfolk River Board in 1957. Subsequently, the Anglian Water Authority, and in 1995 the Environment Agency, took over this role.
